The input is a function `func` with some parameters, the\n * last parameter must be a callback function that `func` calls when it is\n * done.\n *\n * The output of `bindCallback` is a function that takes the same parameters\n * as `func`, except the last one (the callback). When the output function\n * is called with arguments it will return an Observable. If function `func`\n * calls its callback with one argument the Observable will emit that value.\n * If on the other hand the callback is called with multiple values the resulting\n * Observable will emit an array with said values as arguments.\n *\n * It is very important to remember that input function `func` is not called\n * when the output function is, but rather when the Observable returned by the output\n * function is subscribed. This means if `func` makes an AJAX request, that request\n * will be made every time someone subscribes to the resulting Observable, but not before.\n *\n * The last optional parameter - {@link Scheduler} - can be used to control when the call\n * to `func` happens after someone subscribes to Observable, as well as when results\n * passed to callback will be emitted. By default, the subscription to  an Observable calls `func`\n * synchronously, but using `Scheduler.async` as the last parameter will defer the call to `func`,\n * just like wrapping the call in `setTimeout` with a timeout of `0` would. If you use the async Scheduler\n * and call `subscribe` on the output Observable all function calls that are currently executing\n * will end before `func` is invoked.\n *\n * By default results passed to the callback are emitted immediately after `func` invokes the callback.\n * In particular, if the callback is called synchronously the subscription of the resulting Observable\n * will call the `next` function synchronously as well.  If you want to defer that call,\n * you may use `Scheduler.async` just as before.  This means that by using `Scheduler.async` you can\n * ensure that `func` always calls its callback asynchronously, thus avoiding terrifying Zalgo.\n *\n * Note that the Observable created by the output function will always emit a single value\n * and then complete immediately. If `func` calls the callback multiple times, values from subsequent\n * calls will not appear in the stream. If you need to listen for multiple calls,\n *  you probably want to use {@link fromEvent} or {@link fromEventPattern} instead.\n *\n * If `func` depends on some context (`this` property) and is not already bound the context of `func`\n * will be the context that the output function has at call time. In particular, if `func`\n * is called as a method of some objec and if `func` is not already bound, in order to preserve the context\n * it is recommended that the context of the output function is set to that object as well.\n *\n * If the input function calls its callback in the \"node style\" (i.e. first argument to callback is\n * optional error parameter signaling whether the call failed or not), {@link bindNodeCallback}\n * provides convenient error handling and probably is a better choice.\n * `bindCallback` will treat such functions the same as any other and error parameters\n * (whether passed or not) will always be interpreted as regular callback argument.\n *\n *\n * @example <caption>Convert jQuery's getJSON to an Observable API</caption>\n * // Suppose we have jQuery.getJSON('/my/url', callback)\n * var getJSONAsObservable = bindCallback(jQuery.getJSON);\n * var result = getJSONAsObservable('/my/url');\n * result.subscribe(x => console.log(x), e => console.error(e));\n *\n *\n * @example <caption>Receive an array of arguments passed to a callback</caption>\n * someFunction((a, b, c) => {\n *   console.log(a); // 5\n *   console.log(b); // 'some string'\n *   console.log(c); // {someProperty: 'someValue'}\n * });\n *\n * const boundSomeFunction = bindCallback(someFunction);\n * boundSomeFunction().subscribe(values => {\n *   console.log(values) // [5, 'some string', {someProperty: 'someValue'}]\n * });\n *\n *\n * @example <caption>Compare behaviour with and without async Scheduler</caption>\n * function iCallMyCallbackSynchronously(cb) {\n *   cb();\n * }\n *\n * const boundSyncFn = bindCallback(iCallMyCallbackSynchronously);\n * const boundAsyncFn = bindCallback(iCallMyCallbackSynchronously, null, Rx.Scheduler.async);\n *\n * boundSyncFn().subscribe(() => console.log('I was sync!'));\n * boundAsyncFn().subscribe(() => console.log('I was async!'));\n * console.log('This happened...');\n *\n * // Logs:\n * // I was sync!\n * // This happened...\n * // I was async!\n *\n *\n * @example <caption>Use bindCallback on an object method</caption>\n * const boundMethod = bindCallback(someObject.methodWithCallback);\n * boundMethod.call(someObject) // make sure methodWithCallback has access to someObject\n * .subscribe(subscriber);\n *\n *\n * @see {@link bindNodeCallback}\n * @see {@link from}\n * @see {@link fromPromise}\n *\n * @param {function} func A function with a callback as the last parameter.\n * @param {Scheduler} [scheduler] The scheduler on which to schedule the\n * callbacks.\n * @return {function(...params: *): Observable} A function which returns the\n * Observable that delivers the same values the callback would deliver.\n * @name bindCallback\n */\nexport function bindCallback(callbackFunc, resultSelector, scheduler) {\n    if (resultSelector) {\n        if (isScheduler(resultSelector)) {\n            scheduler = resultSelector;\n        }\n        else {\n            // DEPRECATED PATH\n            return function () {\n                var args = [];\n                for (var _i = 0; _i < arguments.length; _i++) {\n                    args[_i] = arguments[_i];\n                }\n                return bindCallback(callbackFunc, scheduler).apply(void 0, args).pipe(map(function (args) { return isArray(args) ?

The input is a function `func` with some parameters, but the\n * last parameter must be a callback function that `func` calls when it is\n * done. The callback function is expected to follow Node.js conventions,\n * where the first argument to the callback is an error object, signaling\n * whether call was successful. If that object is passed to callback, it means\n * something went wrong.\n *\n * The output of `bindNodeCallback` is a function that takes the same\n * parameters as `func`, except the last one (the callback). When the output\n * function is called with arguments, it will return an Observable.\n * If `func` calls its callback with error parameter present, Observable will\n * error with that value as well. If error parameter is not passed, Observable will emit\n * second parameter. If there are more parameters (third and so on),\n * Observable will emit an array with all arguments, except first error argument.\n *\n * Note that `func` will not be called at the same time output function is,\n * but rather whenever resulting Observable is subscribed. By default call to\n * `func` will happen synchronously after subscription, but that can be changed\n * with proper {@link Scheduler} provided as optional third parameter. Scheduler\n * can also control when values from callback will be emitted by Observable.\n * To find out more, check out documentation for {@link bindCallback}, where\n * Scheduler works exactly the same.\n *\n * As in {@link bindCallback}, context (`this` property) of input function will be set to context\n * of returned function, when it is called.\n *\n * After Observable emits value, it will complete immediately. This means\n * even if `func` calls callback again, values from second and consecutive\n * calls will never appear on the stream. If you need to handle functions\n * that call callbacks multiple times, check out {@link fromEvent} or\n * {@link fromEventPattern} instead.\n *\n * Note that `bindNodeCallback` can be used in non-Node.js environments as well.\n * \"Node.js-style\" callbacks are just a convention, so if you write for\n * browsers or any other environment and API you use implements that callback style,\n * `bindNodeCallback` can be safely used on that API functions as well.\n *\n * Remember that Error object passed to callback does not have to be an instance\n * of JavaScript built-in `Error` object. In fact, it does not even have to an object.\n * Error parameter of callback function is interpreted as \"present\", when value\n * of that parameter is truthy. It could be, for example, non-zero number, non-empty\n * string or boolean `true`. In all of these cases resulting Observable would error\n * with that value. This means usually regular style callbacks will fail very often when\n * `bindNodeCallback` is used. If your Observable errors much more often then you\n * would expect, check if callback really is called in Node.js-style and, if not,\n * switch to {@link bindCallback} instead.\n *\n * Note that even if error parameter is technically present in callback, but its value\n * is falsy, it still won't appear in array emitted by Observable.\n *\n *\n * @example <caption>Read a file from the filesystem and get the data as an Observable</caption>\n * import * as fs from 'fs';\n * var readFileAsObservable = bindNodeCallback(fs.readFile);\n * var result = readFileAsObservable('./roadNames.txt', 'utf8');\n * result.subscribe(x => console.log(x), e => console.error(e));\n *\n *\n * @example <caption>Use on function calling callback with multiple arguments</caption>\n * someFunction((err, a, b) => {\n *   console.log(err); // null\n *   console.log(a); // 5\n *   console.log(b); // \"some string\"\n * });\n * var boundSomeFunction = bindNodeCallback(someFunction);\n * boundSomeFunction()\n * .subscribe(value => {\n *   console.log(value); // [5, \"some string\"]\n * });\n *\n * @example <caption>Use on function calling callback in regular style</caption>\n * someFunction(a => {\n *   console.log(a); // 5\n * });\n * var boundSomeFunction = bindNodeCallback(someFunction);\n * boundSomeFunction()\n * .subscribe(\n *   value => {}             // never gets called\n *   err => console.log(err) // 5\n * );\n *\n *\n * @see {@link bindCallback}\n * @see {@link from}\n * @see {@link fromPromise}\n *\n * @param {function} func Function with a Node.js-style callback as the last parameter.\n * @param {Scheduler} [scheduler] The scheduler on which to schedule the\n * callbacks.\n * @return {function(...params: *): Observable} A function which returns the\n * Observable that delivers the same values the Node.js callback would\n * deliver.\n * @name bindNodeCallback\n */\nexport function bindNodeCallback(callbackFunc, resultSelector, scheduler) {\n    if (resultSelector) {\n        if (isScheduler(resultSelector)) {\n            scheduler = resultSelector;\n        }\n        else {\n            // DEPRECATED PATH\n            return function () {\n                var args = [];\n                for (var _i = 0; _i < arguments.length; _i++) {\n                    args[_i] = arguments[_i];\n                }\n                return bindNodeCallback(callbackFunc, scheduler).apply(void 0, args).pipe(map(function (args) { return isArray(args) ?

If no input Observables are provided, resulting stream will complete\n * immediately.\n *\n * `forkJoin` will wait for all passed Observables to complete and then it will emit an array with last\n * values from corresponding Observables. So if you pass `n` Observables to the operator, resulting\n * array will have `n` values, where first value is the last thing emitted by the first Observable,\n * second value is the last thing emitted by the second Observable and so on. That means `forkJoin` will\n * not emit more than once and it will complete after that. If you need to emit combined values not only\n * at the end of lifecycle of passed Observables, but also throughout it, try out {@link combineLatest}\n * or {@link zip} instead.\n *\n * In order for resulting array to have the same length as the number of input Observables, whenever any of\n * that Observables completes without emitting any value, `forkJoin` will complete at that moment as well\n * and it will not emit anything either, even if it already has some last values from other Observables.\n * Conversely, if there is an Observable that never completes, `forkJoin` will never complete as well,\n * unless at any point some other Observable completes without emitting value, which brings us back to\n * the previous case. Overall, in order for `forkJoin` to emit a value, all Observables passed as arguments\n * have to emit something at least once and complete.\n *\n * If any input Observable errors at some point, `forkJoin` will error as well and all other Observables\n * will be immediately unsubscribed.\n *\n * Optionally `forkJoin` accepts project function, that will be called with values which normally\n * would land in emitted array. Whatever is returned by project function, will appear in output\n * Observable instead. This means that default project can be thought of as a function that takes\n * all its arguments and puts them into an array.

Note that this fallback Observable is not checked for timeouts\n * itself, so it can emit values and complete at arbitrary points in time.

You can pass either an array of\n * Observables, or put them directly as arguments. Passing an empty array will result\n * in Observable that completes immediately.\n *\n * `concat` will subscribe to first input Observable and emit all its values, without\n * changing or affecting them in any way.

When last input Observable completes,\n * `concat` will complete as well. At any given moment only one Observable passed to operator\n * emits values. If you would like to emit values from passed Observables concurrently, check out\n * {@link merge} instead, especially with optional `concurrent` parameter. As a matter of fact,\n * `concat` is an equivalent of `merge` operator with `concurrent` parameter set to `1`.\n *\n * Note that if some input Observable never completes, `concat` will also never complete\n * and Observables following the one that did not complete will never be subscribed.

This sets up the\n * `InjectionToken` using this factory as a provider as if it was defined explicitly in the\n * application's root injector. If the factory function, which takes zero arguments, needs to inject\n * dependencies, it can do so using the `inject` function. See below for an example.\n *\n * Additionally, if a `factory` is specified you can also specify the `providedIn` option, which\n * overrides the above behavior and marks the token as belonging to a particular `@NgModule`.

hooks (depending on the node\n// flags in lifecycle). Unlike ngDoCheck, ngOnChanges and ngOnInit, which are\n// called during a pre-order traversal of the view tree (that is calling the\n// parent hooks before the child hooks) these events are sent in using a\n// post-order traversal of the tree (children before parents). This changes the\n// meaning of initIndex in the view state. For ngOnInit, initIndex tracks the\n// expected nodeIndex which a ngOnInit should be called. When sending\n// ngAfterContentInit and ngAfterViewInit it is the expected count of\n// ngAfterContentInit or ngAfterViewInit methods that have been called. This\n// ensure that despite being called recursively or after picking up after an\n// exception, the ngAfterContentInit or ngAfterViewInit will be called on the\n// correct nodes. Consider for example, the following (where E is an element\n// and D is a directive)\n//  Tree:       pre-order index  post-order index\n//    E1        0                6\n//      E2      1                1\n//       D3     2                0\n//      E4      3                5\n//       E5     4                4\n//        E6    5                2\n//        E7    6                3\n// As can be seen, the post-order index has an unclear relationship to the\n// pre-order index (postOrderIndex === preOrderIndex - parentCount +\n// childCount). Since number of calls to ngAfterContentInit and ngAfterViewInit\n// are stable (will be the same for the same view regardless of exceptions or\n// recursion) we just need to count them which will roughly correspond to the\n// post-order index (it skips elements and directives that do not have\n// lifecycle hooks).\n//\n// For example, if an exception is raised in the E6.onAfterViewInit() the\n// initIndex is left at 3 (by shouldCallLifecycleInitHook() which set it to\n// initIndex + 1). When checkAndUpdateView() is called again D3, E2 and E6 will\n// not have their ngAfterViewInit() called but, starting with E7, the rest of\n// the view will begin getting ngAfterViewInit() called until a check and\n// pass is complete.\n//\n// This algorthim also handles recursion. Consider if E4's ngAfterViewInit()\n// indirectly calls E1's ChangeDetectorRef.detectChanges(). The expected\n// initIndex is set to 6, the recusive checkAndUpdateView() starts walk again.\n// D3, E2, E6, E7, E5 and E4 are skipped, ngAfterViewInit() is called on E1.\n// When the recursion returns the initIndex will be 7 so E1 is skipped as it\n// has already been called in the recursively called checkAnUpdateView().\nfunction callLifecycleHooksChildrenFirst(view, lifecycles) {\n    if (!(view.def.nodeFlags & lifecycles)) {\n        return;\n    }\n    var nodes = view.def.nodes;\n    var initIndex = 0;\n    for (var i = 0; i < nodes.length; i++) {\n        var nodeDef = nodes[i];\n        var parent_1 = nodeDef.parent;\n        if (!parent_1 && nodeDef.flags & lifecycles) {\n            // matching root node (e.g. a pipe)\n            callProviderLifecycles(view, i, nodeDef.flags & lifecycles, initIndex++);\n        }\n        if ((nodeDef.childFlags & lifecycles) === 0) {\n            // no child matches one of the lifecycles\n            i += nodeDef.childCount;\n        }\n        while (parent_1 && (parent_1.flags & 1 /* TypeElement */) &&\n            i === parent_1.nodeIndex + parent_1.childCount) {\n            // last child of an element\n            if (parent_1.directChildFlags & lifecycles) {\n                initIndex = callElementProvidersLifecycles(view, parent_1, lifecycles, initIndex);\n            }\n            parent_1 = parent_1.parent;\n        }\n    }\n}\nfunction callElementProvidersLifecycles(view, elDef, lifecycles, initIndex) {\n    for (var i = elDef.nodeIndex + 1; i <= elDef.nodeIndex + elDef.childCount; i++) {\n        var nodeDef = view.def.nodes[i];\n        if (nodeDef.flags & lifecycles) {\n            callProviderLifecycles(view, i, nodeDef.flags & lifecycles, initIndex++);\n        }\n        // only visit direct children\n        i += nodeDef.childCount;\n    }\n    return initIndex;\n}\nfunction callProviderLifecycles(view, index, lifecycles, initIndex) {\n    var providerData = asProviderData(view, index);\n    if (!providerData) {\n        return;\n    }\n    var provider = providerData.instance;\n    if (!provider) {\n        return;\n    }\n    Services.setCurrentNode(view, index);\n    if (lifecycles & 1048576 /* AfterContentInit */ &&\n        shouldCallLifecycleInitHook(view, 512 /* InitState_CallingAfterContentInit */, initIndex)) {\n        provider.ngAfterContentInit();\n    }\n    if (lifecycles & 2097152 /* AfterContentChecked */) {\n        provider.ngAfterContentChecked();\n    }\n    if (lifecycles & 4194304 /* AfterViewInit */ &&\n        shouldCallLifecycleInitHook(view, 768 /* InitState_CallingAfterViewInit */, initIndex)) {\n        provider.ngAfterViewInit();\n    }\n    if (lifecycles & 8388608 /* AfterViewChecked */) {\n        provider.ngAfterViewChecked();\n    }\n    if (lifecycles & 131072 /* OnDestroy */) {\n        provider.ngOnDestroy();\n    }\n}\n/**\n * @license\n * Copyright Google Inc.

If however after that 100ms passes without a second value being emitted,\n * stream will end with an error and source Observable will be unsubscribed.\n * These checks are performed throughout whole lifecycle of Observable - from the moment\n * it was subscribed to, until it completes or errors itself. Thus every value must be\n * emitted within specified period since previous value.\n *\n * If provided argument was Date, returned Observable behaves differently. It throws\n * if Observable did not complete before provided Date. This means that periods between\n * emission of particular values do not matter in this case. If Observable did not complete\n * before provided Date, source Observable will be unsubscribed. Other than that, resulting\n * stream behaves just as source Observable.\n *\n * `timeout` accepts also a Scheduler as a second parameter.

You do\n * **not** need to add a special selector to activate it.\n *\n * ### How to use select controls with form directives\n *\n * To use a select in a template-driven form, simply add an `ngModel` and a `name`\n * attribute to the main `<select>` tag.\n *\n * If your option values are simple strings, you can bind to the normal `value` property\n * on the option.  If your option values happen to be objects (and you'd like to save the\n * selection in your form as an object), use `ngValue` instead:\n *\n * {@example forms/ts/selectControl/select_control_example.ts region='Component'}\n *\n * In reactive forms, you'll also want to add your form directive (`formControlName` or\n * `formControl`) on the main `<select>` tag. Like in the former example, you have the\n * choice of binding to the  `value` or `ngValue` property on the select's options.\n *\n * {@example forms/ts/reactiveSelectControl/reactive_select_control_example.ts region='Component'}\n *\n * ### Caveat: Option selection\n *\n * Angular uses object identity to select option. It's possible for the identities of items\n * to change while the data does not. This can happen, for example, if the items are produced\n * from an RPC to the server, and that RPC is re-run. Even if the data hasn't changed, the\n * second response will produce objects with different identities.\n *\n * To customize the default option comparison algorithm, `<select>` supports `compareWith` input.\n * `compareWith` takes a **function** which has two arguments: `option1` and `option2`.\n * If `compareWith` is given, Angular selects option by the return value of the function.\n *\n * #### Syntax\n *\n * ```\n * <select [compareWith]=\"compareFn\"  [(ngModel)]=\"selectedCountries\">\n *     <option *ngFor=\"let country of countries\" [ngValue]=\"country\">\n *         {{country.name}}\n *     </option>\n * </select>\n *\n * compareFn(c1: Country, c2: Country): boolean {\n *     return c1 && c2 ?

c1.id === c2.id : c1 === c2;\n * }\n * ```\n *\n *\n */\nvar SelectMultipleControlValueAccessor = /*@__PURE__*/ (function () {\n    function SelectMultipleControlValueAccessor(_renderer, _elementRef) {\n        this._renderer = _renderer;\n        this._elementRef = _elementRef;\n        /** @internal */\n        this._optionMap = new Map();\n        /** @internal */\n        this._idCounter = 0;\n        this.onChange = function (_) { };\n        this.onTouched = function () { };\n        this._compareWith = ɵlooseIdentical;\n    }\n    Object.defineProperty(SelectMultipleControlValueAccessor.prototype, \"compareWith\", {\n        set: function (fn) {\n            if (typeof fn !== 'function') {\n                throw new Error(\"compareWith must be a function, but received \" + JSON.stringify(fn));\n            }\n            this._compareWith = fn;\n        },\n        enumerable: true,\n        configurable: true\n    });\n    SelectMultipleControlValueAccessor.prototype.writeValue = function (value) {\n        var _this = this;\n        this.value = value;\n        var optionSelectedStateSetter;\n        if (Array.isArray(value)) {\n            // convert values to ids\n            var ids_1 = value.map(function (v) { return _this._getOptionId(v); });\n            optionSelectedStateSetter = function (opt, o) { opt._setSelected(ids_1.indexOf(o.toString()) > -1); };\n        }\n        else {\n            optionSelectedStateSetter = function (opt, o) { opt._setSelected(false); };\n        }\n        this._optionMap.forEach(optionSelectedStateSetter);\n    };\n    SelectMultipleControlValueAccessor.prototype.registerOnChange = function (fn) {\n        var _this = this;\n        this.onChange = function (_) {\n            var selected = [];\n            if (_.hasOwnProperty('selectedOptions')) {\n                var options = _.selectedOptions;\n                for (var i = 0; i < options.length; i++) {\n                    var opt = options.item(i);\n                    var val = _this._getOptionValue(opt.value);\n                    selected.push(val);\n                }\n            }\n            else {\n                var options = _.options;\n                for (var i = 0; i < options.length; i++) {\n                    var opt = options.item(i);\n                    if (opt.selected) {\n                        var val = _this._getOptionValue(opt.value);\n                        selected.push(val);\n                    }\n                }\n            }\n            _this.value = selected;\n            fn(selected);\n        };\n    };\n    SelectMultipleControlValueAccessor.prototype.registerOnTouched = function (fn) { this.onTouched = fn; };\n    SelectMultipleControlValueAccessor.prototype.setDisabledState = function (isDisabled) {\n        this._renderer.setProperty(this._elementRef.nativeElement, 'disabled', isDisabled);\n    };\n    /** @internal */\n    /** @internal */\n    SelectMultipleControlValueAccessor.prototype._registerOption = /** @internal */\n        function (value) {\n            var id = (this._idCounter++).toString();\n            this._optionMap.set(id, value);\n            return id;\n        };\n    /** @internal */\n    /** @internal */\n    SelectMultipleControlValueAccessor.prototype._getOptionId = /** @internal */\n        function (value) {\n            try {\n                for (var _a = __values(Array.from(this._optionMap.keys())), _b = _a.next(); !_b.done; _b = _a.next()) {\n                    var id = _b.value;\n                    if (this._compareWith(this._optionMap.get(id)._value, value))\n                        return id;\n                }\n            }\n            catch (e_1_1) {\n                e_1 = { error: e_1_1 };\n            }\n            finally {\n                try {\n                    if (_b && !_b.done && (_c = _a.return))\n                        _c.call(_a);\n                }\n                finally {\n                    if (e_1)\n                        throw e_1.error;\n                }\n            }\n            return null;\n            var e_1, _c;\n        };\n    /** @internal */\n    /** @internal */\n    SelectMultipleControlValueAccessor.prototype._getOptionValue = /** @internal */\n        function (valueString) {\n            var id = _extractId$1(valueString);\n            return this._optionMap.has(id) ?

Example:\n *\n * ```ts\n * const ctrl = new FormControl('some value');\n * console.log(ctrl.value);     // 'some value'\n *```\n *\n * You can also initialize the control with a form state object on instantiation,\n * which includes both the value and whether or not the control is disabled.\n * You can't use the value key without the disabled key; both are required\n * to use this way of initialization.\n *\n * ```ts\n * const ctrl = new FormControl({value: 'n/a', disabled: true});\n * console.log(ctrl.value);     // 'n/a'\n * console.log(ctrl.status);   // 'DISABLED'\n * ```\n *\n * The second `FormControl` argument can accept one of three things:\n * * a sync validator function\n * * an array of sync validator functions\n * * an options object containing validator and/or async validator functions\n *\n * Example of a single sync validator function:\n *\n * ```ts\n * const ctrl = new FormControl('', Validators.required);\n * console.log(ctrl.value);     // ''\n * console.log(ctrl.status);   // 'INVALID'\n * ```\n *\n * Example using options object:\n *\n * ```ts\n * const ctrl = new FormControl('', {\n *    validators: Validators.required,\n *    asyncValidators: myAsyncValidator\n * });\n * ```\n *\n * The options object can also be used to define when the control should update.\n * By default, the value and validity of a control updates whenever the value\n * changes. You can configure it to update on the blur event instead by setting\n * the `updateOn` option to `'blur'`.\n *\n * ```ts\n * const c = new FormControl('', { updateOn: 'blur' });\n * ```\n *\n * You can also set `updateOn` to `'submit'`, which will delay value and validity\n * updates until the parent form of the control fires a submit event.\n *\n * See its superclass, `AbstractControl`, for more properties and methods.\n *\n * * **npm package**: `@angular/forms`\n *\n *\n */\nvar FormControl = /*@__PURE__*/ (function (_super) {\n    __extends(FormControl, _super);\n    function FormControl(formState, validatorOrOpts, asyncValidator) {\n        if (formState === void 0) {\n            formState = null;\n        }\n        var _this = _super.call(this, coerceToValidator(validatorOrOpts), coerceToAsyncValidator(asyncValidator, validatorOrOpts)) || this;\n        /** @internal */\n        _this._onChange = [];\n        _this._applyFormState(formState);\n        _this._setUpdateStrategy(validatorOrOpts);\n        _this.updateValueAndValidity({ onlySelf: true, emitEvent: false });\n        _this._initObservables();\n        return _this;\n    }\n    /**\n     * Set the value of the form control to `value`.\n     *\n     * If `onlySelf` is `true`, this change will only affect the validation of this `FormControl`\n     * and not its parent component.

It calculates its status by reducing the statuses\n * of its children. For example, if one of the controls in a group is invalid, the entire\n * group becomes invalid.\n *\n * `FormGroup` is one of the three fundamental building blocks used to define forms in Angular,\n * along with `FormControl` and `FormArray`.\n *\n * When instantiating a `FormGroup`, pass in a collection of child controls as the first\n * argument. The key for each child will be the name under which it is registered.\n *\n * ### Example\n *\n * ```\n * const form = new FormGroup({\n *   first: new FormControl('Nancy', Validators.minLength(2)),\n *   last: new FormControl('Drew'),\n * });\n *\n * console.log(form.value);   // {first: 'Nancy', last; 'Drew'}\n * console.log(form.status);  // 'VALID'\n * ```\n *\n * You can also include group-level validators as the second arg, or group-level async\n * validators as the third arg. These come in handy when you want to perform validation\n * that considers the value of more than one child control.\n *\n * ### Example\n *\n * ```\n * const form = new FormGroup({\n *   password: new FormControl('', Validators.minLength(2)),\n *   passwordConfirm: new FormControl('', Validators.minLength(2)),\n * }, passwordMatchValidator);\n *\n *\n * function passwordMatchValidator(g: FormGroup) {\n *    return g.get('password').value === g.get('passwordConfirm').value\n *       ? null : {'mismatch': true};\n * }\n * ```\n *\n * Like `FormControl` instances, you can alternatively choose to pass in\n * validators and async validators as part of an options object.\n *\n * ```\n * const form = new FormGroup({\n *   password: new FormControl('')\n *   passwordConfirm: new FormControl('')\n * }, {validators: passwordMatchValidator, asyncValidators: otherValidator});\n * ```\n *\n * The options object can also be used to set a default value for each child\n * control's `updateOn` property. If you set `updateOn` to `'blur'` at the\n * group level, all child controls will default to 'blur', unless the child\n * has explicitly specified a different `updateOn` value.\n *\n * ```ts\n * const c = new FormGroup({\n *    one: new FormControl()\n * }, {updateOn: 'blur'});\n * ```\n *\n * * **npm package**: `@angular/forms`\n *\n *\n */\nvar FormGroup = /*@__PURE__*/ (function (_super) {\n    __extends(FormGroup, _super);\n    function FormGroup(controls, validatorOrOpts, asyncValidator) {\n        var _this = _super.call(this, coerceToValidator(validatorOrOpts), coerceToAsyncValidator(asyncValidator, validatorOrOpts)) || this;\n        _this.controls = controls;\n        _this._initObservables();\n        _this._setUpdateStrategy(validatorOrOpts);\n        _this._setUpControls();\n        _this.updateValueAndValidity({ onlySelf: true, emitEvent: false });\n        return _this;\n    }\n    /**\n     * Registers a control with the group's list of controls.\n     *\n     * This method does not update the value or validity of the control, so for most cases you'll want\n     * to use {@link FormGroup#addControl addControl} instead.\n     */\n    /**\n       * Registers a control with the group's list of controls.\n       *\n       * This method does not update the value or validity of the control, so for most cases you'll want\n       * to use {@link FormGroup#addControl addControl} instead.\n       */\n    FormGroup.prototype.registerControl = /**\n       * Registers a control with the group's list of controls.\n       *\n       * This method does not update the value or validity of the control, so for most cases you'll want\n       * to use {@link FormGroup#addControl addControl} instead.\n       */\n        function (name, control) {\n            if (this.controls[name])\n                return this.controls[name];\n            this.controls[name] = control;\n            control.setParent(this);\n            control._registerOnCollectionChange(this._onCollectionChange);\n            return control;\n        };\n    /**\n     * Add a control to this group.\n     */\n    /**\n       * Add a control to this group.\n       */\n    FormGroup.prototype.addControl = /**\n       * Add a control to this group.\n       */\n        function (name, control) {\n            this.registerControl(name, control);\n            this.updateValueAndValidity();\n            this._onCollectionChange();\n        };\n    /**\n     * Remove a control from this group.\n     */\n    /**\n       * Remove a control from this group.\n       */\n    FormGroup.prototype.removeControl = /**\n       * Remove a control from this group.\n       */\n        function (name) {\n            if (this.controls[name])\n                this.controls[name]._registerOnCollectionChange(function () { });\n            delete (this.controls[name]);\n            this.updateValueAndValidity();\n            this._onCollectionChange();\n        };\n    /**\n     * Replace an existing control.\n     */\n    /**\n       * Replace an existing control.\n       */\n    FormGroup.prototype.setControl = /**\n       * Replace an existing control.\n       */\n        function (name, control) {\n            if (this.controls[name])\n                this.controls[name]._registerOnCollectionChange(function () { });\n            delete (this.controls[name]);\n            if (control)\n                this.registerControl(name, control);\n            this.updateValueAndValidity();\n            this._onCollectionChange();\n        };\n    /**\n     * Check whether there is an enabled control with the given name in the group.\n     *\n     * It will return false for disabled controls.

For example, if one of\n * the controls in a `FormArray` is invalid, the entire array becomes invalid.\n *\n * `FormArray` is one of the three fundamental building blocks used to define forms in Angular,\n * along with `FormControl` and `FormGroup`.\n *\n * When instantiating a `FormArray`, pass in an array of child controls as the first\n * argument.\n *\n * ### Example\n *\n * ```\n * const arr = new FormArray([\n *   new FormControl('Nancy', Validators.minLength(2)),\n *   new FormControl('Drew'),\n * ]);\n *\n * console.log(arr.value);   // ['Nancy', 'Drew']\n * console.log(arr.status);  // 'VALID'\n * ```\n *\n * You can also include array-level validators and async validators. These come in handy\n * when you want to perform validation that considers the value of more than one child\n * control.\n *\n * The two types of validators can be passed in separately as the second and third arg\n * respectively, or together as part of an options object.\n *\n * ```\n * const arr = new FormArray([\n *   new FormControl('Nancy'),\n *   new FormControl('Drew')\n * ], {validators: myValidator, asyncValidators: myAsyncValidator});\n * ```\n *\n * The options object can also be used to set a default value for each child\n * control's `updateOn` property. If you set `updateOn` to `'blur'` at the\n * array level, all child controls will default to 'blur', unless the child\n * has explicitly specified a different `updateOn` value.\n *\n * ```ts\n * const c = new FormArray([\n *    new FormControl()\n * ], {updateOn: 'blur'});\n * ```\n *\n * ### Adding or removing controls\n *\n * To change the controls in the array, use the `push`, `insert`, or `removeAt` methods\n * in `FormArray` itself. These methods ensure the controls are properly tracked in the\n * form's hierarchy. Do not modify the array of `AbstractControl`s used to instantiate\n * the `FormArray` directly, as that will result in strange and unexpected behavior such\n * as broken change detection.\n *\n * * **npm package**: `@angular/forms`\n *\n *\n */\nvar FormArray = /*@__PURE__*/ (function (_super) {\n    __extends(FormArray, _super);\n    function FormArray(controls, validatorOrOpts, asyncValidator) {\n        var _this = _super.call(this, coerceToValidator(validatorOrOpts), coerceToAsyncValidator(asyncValidator, validatorOrOpts)) || this;\n        _this.controls = controls;\n        _this._initObservables();\n        _this._setUpdateStrategy(validatorOrOpts);\n        _this._setUpControls();\n        _this.updateValueAndValidity({ onlySelf: true, emitEvent: false });\n        return _this;\n    }\n    /**\n     * Get the `AbstractControl` at the given `index` in the array.\n     */\n    /**\n       * Get the `AbstractControl` at the given `index` in the array.\n       */\n    FormArray.prototype.at = /**\n       * Get the `AbstractControl` at the given `index` in the array.\n       */\n        function (index) { return this.controls[index]; };\n    /**\n     * Insert a new `AbstractControl` at the end of the array.\n     */\n    /**\n       * Insert a new `AbstractControl` at the end of the array.\n       */\n    FormArray.prototype.push = /**\n       * Insert a new `AbstractControl` at the end of the array.\n       */\n        function (control) {\n            this.controls.push(control);\n            this._registerControl(control);\n            this.updateValueAndValidity();\n            this._onCollectionChange();\n        };\n    /** Insert a new `AbstractControl` at the given `index` in the array. */\n    /** Insert a new `AbstractControl` at the given `index` in the array. */\n    FormArray.prototype.insert = /** Insert a new `AbstractControl` at the given `index` in the array. */\n        function (index, control) {\n            this.controls.splice(index, 0, control);\n            this._registerControl(control);\n            this.updateValueAndValidity();\n        };\n    /** Remove the control at the given `index` in the array. */\n    /** Remove the control at the given `index` in the array. */\n    FormArray.prototype.removeAt = /** Remove the control at the given `index` in the array. */\n        function (index) {\n            if (this.controls[index])\n                this.controls[index]._registerOnCollectionChange(function () { });\n            this.controls.splice(index, 1);\n            this.updateValueAndValidity();\n        };\n    /**\n     * Replace an existing control.\n     */\n    /**\n       * Replace an existing control.\n       */\n    FormArray.prototype.setControl = /**\n       * Replace an existing control.\n       */\n        function (index, control) {\n            if (this.controls[index])\n                this.controls[index]._registerOnCollectionChange(function () { });\n            this.controls.splice(index, 1);\n            if (control) {\n                this.controls.splice(index, 0, control);\n                this._registerControl(control);\n            }\n            this.updateValueAndValidity();\n            this._onCollectionChange();\n        };\n    Object.defineProperty(FormArray.prototype, \"length\", {\n        /**\n         * Length of the control array.\n         */\n        get: /**\n           * Length of the control array.\n           */ function () { return this.controls.length; },\n        enumerable: true,\n        configurable: true\n    });\n    /**\n     *  Sets the value of the `FormArray`.

You don't need to add a special selector.\n *\n * You can export the directive into a local template variable using `ngForm` as the key\n * (ex: `#myForm=\"ngForm\"`). This is optional, but useful.  Many properties from the underlying\n * `FormGroup` instance are duplicated on the directive itself, so a reference to it\n * will give you access to the aggregate value and validity status of the form, as well as\n * user interaction properties like `dirty` and `touched`.\n *\n * To register child controls with the form, you'll want to use `NgModel` with a\n * `name` attribute.  You can also use `NgModelGroup` if you'd like to create\n * sub-groups within the form.\n *\n * You can listen to the directive's `ngSubmit` event to be notified when the user has\n * triggered a form submission.

Conversely,\n * any values written to the DOM element through user input will be reflected in the\n * `FormControl` instance (view -> model).\n *\n * Use this directive if you'd like to create and manage a `FormControl` instance directly.\n * Simply create a `FormControl`, save it to your component class, and pass it into the\n * `FormControlDirective`.\n *\n * This directive is designed to be used as a standalone control.  Unlike `FormControlName`,\n * it does not require that your `FormControl` instance be part of any parent\n * `FormGroup`, and it won't be registered to any `FormGroupDirective` that\n * exists above it.\n *\n * **Get the value**: the `value` property is always synced and available on the\n * `FormControl` instance. See a full list of available properties in\n * `AbstractControl`.\n *\n * **Set the value**: You can pass in an initial value when instantiating the `FormControl`,\n * or you can set it programmatically later using {@link AbstractControl#setValue setValue} or\n * {@link AbstractControl#patchValue patchValue}.\n *\n * **Listen to value**: If you want to listen to changes in the value of the control, you can\n * subscribe to the {@link AbstractControl#valueChanges valueChanges} event.  You can also listen to\n * {@link AbstractControl#statusChanges statusChanges} to be notified when the validation status is\n * re-calculated.\n *\n * ### Example\n *\n * {@example forms/ts/simpleFormControl/simple_form_control_example.ts region='Component'}\n *\n * * **npm package**: `@angular/forms`\n *\n * * **NgModule**: `ReactiveFormsModule`\n *\n * ### Use with ngModel\n *\n * Support for using the `ngModel` input property and `ngModelChange` event with reactive\n * form directives has been deprecated in Angular v6 and will be removed in Angular v7.\n *\n * Now deprecated:\n * ```html\n * <input [formControl]=\"control\" [(ngModel)]=\"value\">\n * ```\n *\n * ```ts\n * this.value = 'some value';\n * ```\n *\n * This has been deprecated for a few reasons. First, developers have found this pattern\n * confusing. It seems like the actual `ngModel` directive is being used, but in fact it's\n * an input/output property named `ngModel` on the reactive form directive that simply\n * approximates (some of) its behavior. Specifically, it allows getting/setting the value\n * and intercepting value events. However, some of `ngModel`'s other features - like\n * delaying updates with`ngModelOptions` or exporting the directive - simply don't work,\n * which has understandably caused some confusion.\n *\n * In addition, this pattern mixes template-driven and reactive forms strategies, which\n * we generally don't recommend because it doesn't take advantage of the full benefits of\n * either strategy. Setting the value in the template violates the template-agnostic\n * principles behind reactive forms, whereas adding a `FormControl`/`FormGroup` layer in\n * the class removes the convenience of defining forms in the template.\n *\n * To update your code before v7, you'll want to decide whether to stick with reactive form\n * directives (and get/set values using reactive forms patterns) or switch over to\n * template-driven directives.\n *\n * After (choice 1 - use reactive forms):\n *\n * ```html\n * <input [formControl]=\"control\">\n * ```\n *\n * ```ts\n * this.control.setValue('some value');\n * ```\n *\n * After (choice 2 - use template-driven forms):\n *\n * ```html\n * <input [(ngModel)]=\"value\">\n * ```\n *\n * ```ts\n * this.value = 'some value';\n * ```\n *\n * By default, when you use this pattern, you will see a deprecation warning once in dev\n * mode.

First, developers have found this pattern\n * confusing. It seems like the actual `ngModel` directive is being used, but in fact it's\n * an input/output property named `ngModel` on the reactive form directive that simply\n * approximates (some of) its behavior. Specifically, it allows getting/setting the value\n * and intercepting value events. However, some of `ngModel`'s other features - like\n * delaying updates with`ngModelOptions` or exporting the directive - simply don't work,\n * which has understandably caused some confusion.\n *\n * In addition, this pattern mixes template-driven and reactive forms strategies, which\n * we generally don't recommend because it doesn't take advantage of the full benefits of\n * either strategy. Setting the value in the template violates the template-agnostic\n * principles behind reactive forms, whereas adding a `FormControl`/`FormGroup` layer in\n * the class removes the convenience of defining forms in the template.\n *\n * To update your code before v7, you'll want to decide whether to stick with reactive form\n * directives (and get/set values using reactive forms patterns) or switch over to\n * template-driven directives.\n *\n * After (choice 1 - use reactive forms):\n *\n * ```html\n * <form [formGroup]=\"form\">\n *   <input formControlName=\"first\">\n * </form>\n * ```\n *\n * ```ts\n * this.form.get('first').setValue('some value');\n * ```\n *\n * After (choice 2 - use template-driven forms):\n *\n * ```html\n * <input [(ngModel)]=\"value\">\n * ```\n *\n * ```ts\n * this.value = 'some value';\n * ```\n *\n * By default, when you use this pattern, you will see a deprecation warning once in dev\n * mode.

As a second argument it takes string that indicates\n * type of event we want to listen for. `fromEvent` supports selected types of event targets,\n * which are described in detail below. If your event target does not match any of the ones listed,\n * you should use {@link fromEventPattern}, which can be used on arbitrary APIs.\n * When it comes to APIs supported by `fromEvent`, their methods for adding and removing event\n * handler functions have different names, but they all accept a string describing event type\n * and function itself, which will be called whenever said event happens.\n *\n * Every time resulting Observable is subscribed, event handler function will be registered\n * to event target on given event type. When that event fires, value\n * passed as a first argument to registered function will be emitted by output Observable.\n * When Observable is unsubscribed, function will be unregistered from event target.\n *\n * Note that if event target calls registered function with more than one argument, second\n * and following arguments will not appear in resulting stream. In order to get access to them,\n * you can pass to `fromEvent` optional project function, which will be called with all arguments\n * passed to event handler. Output Observable will then emit value returned by project function,\n * instead of the usual value.\n *\n * Remember that event targets listed below are checked via duck typing. It means that\n * no matter what kind of object you have and no matter what environment you work in,\n * you can safely use `fromEvent` on that object if it exposes described methods (provided\n * of course they behave as was described above). So for example if Node.js library exposes\n * event target which has the same method names as DOM EventTarget, `fromEvent` is still\n * a good choice.\n *\n * If the API you use is more callback then event handler oriented (subscribed\n * callback function fires only once and thus there is no need to manually\n * unregister it), you should use {@link bindCallback} or {@link bindNodeCallback}\n * instead.\n *\n * `fromEvent` supports following types of event targets:\n *\n * **DOM EventTarget**\n *\n * This is an object with `addEventListener` and `removeEventListener` methods.\n *\n * In the browser, `addEventListener` accepts - apart from event type string and event\n * handler function arguments - optional third parameter, which is either an object or boolean,\n * both used for additional configuration how and when passed function will be called. When\n * `fromEvent` is used with event target of that type, you can provide this values\n * as third parameter as well.\n *\n * **Node.js EventEmitter**\n *\n * An object with `addListener` and `removeListener` methods.\n *\n * **JQuery-style event target**\n *\n * An object with `on` and `off` methods\n *\n * **DOM NodeList**\n *\n * List of DOM Nodes, returned for example by `document.querySelectorAll` or `Node.childNodes`.\n *\n * Although this collection is not event target in itself, `fromEvent` will iterate over all Nodes\n * it contains and install event handler function in every of them. When returned Observable\n * is unsubscribed, function will be removed from all Nodes.\n *\n * **DOM HtmlCollection**\n *\n * Just as in case of NodeList it is a collection of DOM nodes. Here as well event handler function is\n * installed and removed in each of elements.\n *\n *\n * @example <caption>Emits clicks happening on the DOM document</caption>\n * var clicks = fromEvent(document, 'click');\n * clicks.subscribe(x => console.log(x));\n *\n * // Results in:\n * // MouseEvent object logged to console every time a click\n * // occurs on the document.\n *\n *\n * @example <caption>Use addEventListener with capture option</caption>\n * var clicksInDocument = fromEvent(document, 'click', true); // note optional configuration parameter\n *                                                                          // which will be passed to addEventListener\n * var clicksInDiv = fromEvent(someDivInDocument, 'click');\n *\n * clicksInDocument.subscribe(() => console.log('document'));\n * clicksInDiv.subscribe(() => console.log('div'));\n *\n * // By default events bubble UP in DOM tree, so normally\n * // when we would click on div in document\n * // \"div\" would be logged first and then \"document\".\n * // Since we specified optional `capture` option, document\n * // will catch event when it goes DOWN DOM tree, so console\n * // will log \"document\" and then \"div\".\n *\n * @see {@link bindCallback}\n * @see {@link bindNodeCallback}\n * @see {@link fromEventPattern}\n *\n * @param {FromEventTarget<T>} target The DOM EventTarget, Node.js\n * EventEmitter, JQuery-like event target, NodeList or HTMLCollection to attach the event handler to.\n * @param {string} eventName The event name of interest, being emitted by the\n * `target`.\n * @param {EventListenerOptions} [options] Options to pass through to addEventListener\n * @return {Observable<T>}\n * @name fromEvent\n */\nexport function fromEvent(target, eventName, options, resultSelector) {\n    if (isFunction(options)) {\n        // DEPRECATED PATH\n        resultSelector = options;\n        options = undefined;\n    }\n    if (resultSelector) {\n        // DEPRECATED PATH\n        return fromEvent(target, eventName, options).pipe(map(function (args) { return isArray(args) ? resultSelector.apply(void 0, args) : resultSelector(args); }));\n    }\n    return new Observable(function (subscriber) {\n        function handler(e) {\n            if (arguments.length > 1) {\n                subscriber.next(Array.prototype.slice.call(arguments));\n            }\n            else {\n                subscriber.next(e);\n            }\n        }\n        setupSubscription(target, eventName, handler, subscriber, options);\n    });\n}\nfunction setupSubscription(sourceObj, eventName, handler, subscriber, options) {\n    var unsubscribe;\n    if (isEventTarget(sourceObj)) {\n        var source_1 = sourceObj;\n        sourceObj.addEventListener(eventName, handler, options);\n        unsubscribe = function () { return source_1.removeEventListener(eventName, handler, options); };\n    }\n    else if (isJQueryStyleEventEmitter(sourceObj)) {\n        var source_2 = sourceObj;\n        sourceObj.on(eventName, handler);\n        unsubscribe = function () { return source_2.off(eventName, handler); };\n    }\n    else if (isNodeStyleEventEmitter(sourceObj)) {\n        var source_3 = sourceObj;\n        sourceObj.addListener(eventName, handler);\n        unsubscribe = function () { return source_3.removeListener(eventName, handler); };\n    }\n    else if (sourceObj && sourceObj.length) {\n        for (var i = 0, len = sourceObj.length; i < len; i++) {\n            setupSubscription(sourceObj[i], eventName, handler, subscriber, options);\n        }\n    }\n    else {\n        throw new TypeError('Invalid event target');\n    }\n    subscriber.add(unsubscribe);\n}\nfunction isNodeStyleEventEmitter(sourceObj) {\n    return sourceObj && typeof sourceObj.addListener === 'function' && typeof sourceObj.removeListener === 'function';\n}\nfunction isJQueryStyleEventEmitter(sourceObj) {\n    return sourceObj && typeof sourceObj.on === 'function' && typeof sourceObj.off === 'function';\n}\nfunction isEventTarget(sourceObj) {\n    return sourceObj && typeof sourceObj.addEventListener === 'function' && typeof sourceObj.removeEventListener === 'function';\n}\n//# sourceMappingURL=fromEvent.js.map\n",null]}

You can achieve this in two\n     * following ways.\n     *\n     * The first way is creating an object that implements {@link Observer} interface. It should have methods\n     * defined by that interface, but note that it should be just a regular JavaScript object, which you can create\n     * yourself in any way you want (ES6 class, classic function constructor, object literal etc.). In particular do\n     * not attempt to use any RxJS implementation details to create Observers - you don't need them. Remember also\n     * that your object does not have to implement all methods. If you find yourself creating a method that doesn't\n     * do anything, you can simply omit it. Note however, that if `error` method is not provided, all errors will\n     * be left uncaught.\n     *\n     * The second way is to give up on Observer object altogether and simply provide callback functions in place of its methods.\n     * This means you can provide three functions as arguments to `subscribe`, where first function is equivalent\n     * of a `next` method, second of an `error` method and third of a `complete` method. Just as in case of Observer,\n     * if you do not need to listen for something, you can omit a function, preferably by passing `undefined` or `null`,\n     * since `subscribe` recognizes these functions by where they were placed in function call. When it comes\n     * to `error` function, just as before, if not provided, errors emitted by an Observable will be thrown.\n     *\n     * Whatever style of calling `subscribe` you use, in both cases it returns a Subscription object.\n     * This object allows you to call `unsubscribe` on it, which in turn will stop work that an Observable does and will clean\n     * up all resources that an Observable used. Note that cancelling a subscription will not call `complete` callback\n     * provided to `subscribe` function, which is reserved for a regular completion signal that comes from an Observable.\n     *\n     * Remember that callbacks provided to `subscribe` are not guaranteed to be called asynchronously.\n     * It is an Observable itself that decides when these functions will be called. For example {@link of}\n     * by default emits all its values synchronously.

The context\n * for each instantiated template inherits from the outer context with the given loop variable\n * set to the current item from the iterable.\n *\n * ### Local Variables\n *\n * `NgForOf` provides several exported values that can be aliased to local variables:\n *\n * - `$implicit: T`: The value of the individual items in the iterable (`ngForOf`).\n * - `ngForOf: NgIterable<T>`: The value of the iterable expression. Useful when the expression is\n * more complex then a property access, for example when using the async pipe (`userStreams |\n * async`).\n * - `index: number`: The index of the current item in the iterable.\n * - `first: boolean`: True when the item is the first item in the iterable.\n * - `last: boolean`: True when the item is the last item in the iterable.\n * - `even: boolean`: True when the item has an even index in the iterable.\n * - `odd: boolean`: True when the item has an odd index in the iterable.\n *\n * ```\n * <li *ngFor=\"let user of userObservable | async as users; index as i; first as isFirst\">\n *    {{i}}/{{users.length}}. {{user}} <span *ngIf=\"isFirst\">default</span>\n * </li>\n * ```\n *\n * ### Change Propagation\n *\n * When the contents of the iterator changes, `NgForOf` makes the corresponding changes to the DOM:\n *\n * * When an item is added, a new instance of the template is added to the DOM.\n * * When an item is removed, its template instance is removed from the DOM.\n * * When items are reordered, their respective templates are reordered in the DOM.\n * * Otherwise, the DOM element for that item will remain the same.\n *\n * Angular uses object identity to track insertions and deletions within the iterator and reproduce\n * those changes in the DOM. This has important implications for animations and any stateful\n * controls (such as `<input>` elements which accept user input) that are present. Inserted rows can\n * be animated in, deleted rows can be animated out, and unchanged rows retain any unsaved state\n * such as user input.\n *\n * It is possible for the identities of elements in the iterator to change while the data does not.\n * This can happen, for example, if the iterator produced from an RPC to the server, and that\n * RPC is re-run. Even if the data hasn't changed, the second response will produce objects with\n * different identities, and Angular will tear down the entire DOM and rebuild it (as if all old\n * elements were deleted and all new elements inserted). This is an expensive operation and should\n * be avoided if possible.\n *\n * To customize the default tracking algorithm, `NgForOf` supports `trackBy` option.\n * `trackBy` takes a function which has two arguments: `index` and `item`.\n * If `trackBy` is given, Angular tracks changes by the return value of the function.\n *\n * ### Syntax\n *\n * - `<li *ngFor=\"let item of items; index as i; trackBy: trackByFn\">...</li>`\n *\n * With `<ng-template>` element:\n *\n * ```\n * <ng-template ngFor let-item [ngForOf]=\"items\" let-i=\"index\" [ngForTrackBy]=\"trackByFn\">\n *   <li>...</li>\n * </ng-template>\n * ```\n *\n * ### Example\n *\n * See a [live demo](http://plnkr.co/edit/KVuXxDp0qinGDyo307QW?p=preview) for a more detailed\n * example.\n *\n *\n */\nvar NgForOf = /*@__PURE__*/ (function () {\n    function NgForOf(_viewContainer, _template, _differs) {\n        this._viewContainer = _viewContainer;\n        this._template = _template;\n        this._differs = _differs;\n        this._differ = null;\n    }\n    Object.defineProperty(NgForOf.prototype, \"ngForTrackBy\", {\n        get: function () { return this._trackByFn; },\n        set: function (fn) {\n            if (isDevMode() && fn != null && typeof fn !== 'function') {\n                // TODO(vicb): use a log service once there is a public one available\n                if (console && console.warn) {\n                    console.warn(\"trackBy must be a function, but received \" + JSON.stringify(fn) + \". \" +\n                        \"See https://angular.io/docs/ts/latest/api/common/index/NgFor-directive.html#!#change-propagation for more information.\");\n                }\n            }\n            this._trackByFn = fn;\n        },\n        enumerable: true,\n        configurable: true\n    });\n    Object.defineProperty(NgForOf.prototype, \"ngForTemplate\", {\n        set: function (value) {\n            // TODO(TS2.1): make TemplateRef<Partial<NgForRowOf<T>>> once we move to TS v2.1\n            // The current type is too restrictive; a template that just uses index, for example,\n            // should be acceptable.\n            if (value) {\n                this._template = value;\n            }\n        },\n        enumerable: true,\n        configurable: true\n    });\n    NgForOf.prototype.ngOnChanges = function (changes) {\n        if ('ngForOf' in changes) {\n            // React on ngForOf changes only once all inputs have been initialized\n            var value = changes['ngForOf'].currentValue;\n            if (!this._differ && value) {\n                try {\n                    this._differ = this._differs.find(value).create(this.ngForTrackBy);\n                }\n                catch (e) {\n                    throw new Error(\"Cannot find a differ supporting object '\" + value + \"' of type '\" + getTypeNameForDebugging(value) + \"'.

Typically the:\n *  - `then` template is the inline template of `ngIf` unless bound to a different value.\n *  - `else` template is blank unless it is bound.\n *\n * ## Most common usage\n *\n * The most common usage of the `ngIf` directive is to conditionally show the inline template as\n * seen in this example:\n * {@example common/ngIf/ts/module.ts region='NgIfSimple'}\n *\n * ## Showing an alternative template using `else`\n *\n * If it is necessary to display a template when the `expression` is falsy use the `else` template\n * binding as shown. Note that the `else` binding points to a `<ng-template>` labeled `#elseBlock`.\n * The template can be defined anywhere in the component view but is typically placed right after\n * `ngIf` for readability.\n *\n * {@example common/ngIf/ts/module.ts region='NgIfElse'}\n *\n * ## Using non-inlined `then` template\n *\n * Usually the `then` template is the inlined template of the `ngIf`, but it can be changed using\n * a binding (just like `else`). Because `then` and `else` are bindings, the template references can\n * change at runtime as shown in this example.\n *\n * {@example common/ngIf/ts/module.ts region='NgIfThenElse'}\n *\n * ## Storing conditional result in a variable\n *\n * A common pattern is that we need to show a set of properties from the same object. If the\n * object is undefined, then we have to use the safe-traversal-operator `?.` to guard against\n * dereferencing a `null` value. This is especially the case when waiting on async data such as\n * when using the `async` pipe as shown in following example:\n *\n * ```\n * Hello {{ (userStream|async)?.last }}, {{ (userStream|async)?.first }}!\n * ```\n *\n * There are several inefficiencies in the above example:\n *  - We create multiple subscriptions on `userStream`. One for each `async` pipe, or two in the\n *    example above.\n *  - We cannot display an alternative screen while waiting for the data to arrive asynchronously.\n *  - We have to use the safe-traversal-operator `?.` to access properties, which is cumbersome.\n *  - We have to place the `async` pipe in parenthesis.\n *\n * A better way to do this is to use `ngIf` and store the result of the condition in a local\n * variable as shown in the the example below:\n *\n * {@example common/ngIf/ts/module.ts region='NgIfAs'}\n *\n * Notice that:\n *  - We use only one `async` pipe and hence only one subscription gets created.\n *  - `ngIf` stores the result of the `userStream|async` in the local variable `user`.\n *  - The local `user` can then be bound repeatedly in a more efficient way.\n *  - No need to use the safe-traversal-operator `?.` to access properties as `ngIf` will only\n *    display the data if `userStream` returns a value.\n *  - We can display an alternative template while waiting for the data.\n *\n * ### Syntax\n *\n * Simple form:\n * - `<div *ngIf=\"condition\">...</div>`\n * - `<ng-template [ngIf]=\"condition\"><div>...</div></ng-template>`\n *\n * Form with an else block:\n * ```\n * <div *ngIf=\"condition; else elseBlock\">...</div>\n * <ng-template #elseBlock>...</ng-template>\n * ```\n *\n * Form with a `then` and `else` block:\n * ```\n * <div *ngIf=\"condition; then thenBlock else elseBlock\"></div>\n * <ng-template #thenBlock>...</ng-template>\n * <ng-template #elseBlock>...</ng-template>\n * ```\n *\n * Form with storing the value locally:\n * ```\n * <div *ngIf=\"condition as value; else elseBlock\">{{value}}</div>\n * <ng-template #elseBlock>...</ng-template>\n * ```\n *\n *\n */\nvar NgIf = /*@__PURE__*/ (function () {\n    function NgIf(_viewContainer, templateRef) {\n        this._viewContainer = _viewContainer;\n        this._context = new NgIfContext();\n        this._thenTemplateRef = null;\n        this._elseTemplateRef = null;\n        this._thenViewRef = null;\n        this._elseViewRef = null;\n        this._thenTemplateRef = templateRef;\n    }\n    Object.defineProperty(NgIf.prototype, \"ngIf\", {\n        set: function (condition) {\n            this._context.$implicit = this._context.ngIf = condition;\n            this._updateView();\n        },\n        enumerable: true,\n        configurable: true\n    });\n    Object.defineProperty(NgIf.prototype, \"ngIfThen\", {\n        set: function (templateRef) {\n            assertTemplate('ngIfThen', templateRef);\n            this._thenTemplateRef = templateRef;\n            this._thenViewRef = null; // clear previous view if any.\n            this._updateView();\n        },\n        enumerable: true,\n        configurable: true\n    });\n    Object.defineProperty(NgIf.prototype, \"ngIfElse\", {\n        set: function (templateRef) {\n            assertTemplate('ngIfElse', templateRef);\n            this._elseTemplateRef = templateRef;\n            this._elseViewRef = null; // clear previous view if any.\n            this._updateView();\n        },\n        enumerable: true,\n        configurable: true\n    });\n    NgIf.prototype._updateView = function () {\n        if (this._context.$implicit) {\n            if (!this._thenViewRef) {\n                this._viewContainer.clear();\n                this._elseViewRef = null;\n                if (this._thenTemplateRef) {\n                    this._thenViewRef =\n                        this._viewContainer.createEmbeddedView(this._thenTemplateRef, this._context);\n                }\n            }\n        }\n        else {\n            if (!this._elseViewRef) {\n                this._viewContainer.clear();\n                this._thenViewRef = null;\n                if (this._elseTemplateRef) {\n                    this._elseViewRef =\n                        this._viewContainer.createEmbeddedView(this._elseTemplateRef, this._context);\n                }\n            }\n        }\n    };\n    return NgIf;\n}());\nvar NgIfContext = /*@__PURE__*/ (function () {\n    function NgIfContext() {\n        this.$implicit = null;\n        this.ngIf = null;\n    }\n    return NgIfContext;\n}());\nfunction assertTemplate(property, templateRef) {\n    var isTemplateRefOrNull = !!(!templateRef || templateRef.createEmbeddedView);\n    if (!isTemplateRefOrNull) {\n        throw new Error(property + \" must be a TemplateRef, but received '\" + ɵstringify(templateRef) + \"'.\");\n    }\n}\n/**\n * @license\n * Copyright Google Inc.

This is done by subscribing to each Observable in order and,\n * whenever any Observable emits, collecting an array of the most recent\n * values from each Observable. So if you pass `n` Observables to operator,\n * returned Observable will always emit an array of `n` values, in order\n * corresponding to order of passed Observables (value from the first Observable\n * on the first place and so on).\n *\n * Static version of `combineLatest` accepts either an array of Observables\n * or each Observable can be put directly as an argument. Note that array of\n * Observables is good choice, if you don't know beforehand how many Observables\n * you will combine. Passing empty array will result in Observable that\n * completes immediately.\n *\n * To ensure output array has always the same length, `combineLatest` will\n * actually wait for all input Observables to emit at least once,\n * before it starts emitting results. This means if some Observable emits\n * values before other Observables started emitting, all that values but last\n * will be lost. On the other hand, is some Observable does not emit value but\n * completes, resulting Observable will complete at the same moment without\n * emitting anything, since it will be now impossible to include value from\n * completed Observable in resulting array. Also, if some input Observable does\n * not emit any value and never completes, `combineLatest` will also never emit\n * and never complete, since, again, it will wait for all streams to emit some\n * value.\n *\n * If at least one Observable was passed to `combineLatest` and all passed Observables\n * emitted something, resulting Observable will complete when all combined\n * streams complete. So even if some Observable completes, result of\n * `combineLatest` will still emit values when other Observables do. In case\n * of completed Observable, its value from now on will always be the last\n * emitted value. On the other hand, if any Observable errors, `combineLatest`\n * will error immediately as well, and all other Observables will be unsubscribed.\n *\n * `combineLatest` accepts as optional parameter `project` function, which takes\n * as arguments all values that would normally be emitted by resulting Observable.\n * `project` can return any kind of value, which will be then emitted by Observable\n * instead of default array. Note that `project` does not take as argument that array\n * of values, but values themselves. That means default `project` can be imagined\n * as function that takes all its arguments and puts them into an array.\n *\n *\n * @example <caption>Combine two timer Observables</caption>\n * const firstTimer = Rx.Observable.timer(0, 1000);

That being said, if you need to schedule task asynchronously, but\n * as soon as possible, `asap` scheduler is your best bet.\n *\n * @example <caption>Compare async and asap scheduler</caption>\n *\n * Rx.Scheduler.async.schedule(() => console.log('async')); // scheduling 'async' first...\n * Rx.Scheduler.asap.schedule(() => console.log('asap'));\n *\n * // Logs:\n * // \"asap\"\n * // \"async\"\n * // ... but 'asap' goes first!\n *\n * @static true\n * @name asap\n * @owner Scheduler\n */\nexport var asap = /*@__PURE__*/ new AsapScheduler(AsapAction);\n//# sourceMappingURL=asap.js.map\n",null]}

It might be useful, if you do not have control over\n * internal scheduler of a given Observable, but want to control when its values are emitted nevertheless.\n *\n * Returned Observable emits the same notifications (nexted values, complete and error events) as the source Observable,\n * but rescheduled with provided scheduler. Note that this doesn't mean that source Observables internal\n * scheduler will be replaced in any way. Original scheduler still will be used, but when the source Observable emits\n * notification, it will be immediately scheduled again - this time with scheduler passed to `observeOn`.\n * An anti-pattern would be calling `observeOn` on Observable that emits lots of values synchronously, to split\n * that emissions into asynchronous chunks. For this to happen, scheduler would have to be passed into the source\n * Observable directly (usually into the operator that creates it). `observeOn` simply delays notifications a\n * little bit more, to ensure that they are emitted at expected moments.\n *\n * As a matter of fact, `observeOn` accepts second parameter, which specifies in milliseconds with what delay notifications\n * will be emitted. The main difference between {@link delay} operator and `observeOn` is that `observeOn`\n * will delay all notifications - including error notifications - while `delay` will pass through error\n * from source Observable immediately when it is emitted. In general it is highly recommended to use `delay` operator\n * for any kind of delaying of values in the stream, while using `observeOn` to specify which scheduler should be used\n * for notification emissions in general.\n *\n * @example <caption>Ensure values in subscribe are called just before browser repaint.</caption>\n * const intervals = Rx.Observable.interval(10); // Intervals are scheduled\n *                                               // with async scheduler by default...\n *\n * intervals\n * .observeOn(Rx.Scheduler.animationFrame)       // ...but we will observe on animationFrame\n * .subscribe(val => {                           // scheduler to ensure smooth animation.\n *   someDiv.style.height = val + 'px';\n * });\n *\n * @see {@link delay}\n *\n * @param {SchedulerLike} scheduler Scheduler that will be used to reschedule notifications from source Observable.\n * @param {number} [delay] Number of milliseconds that states with what delay every notification should be rescheduled.\n * @return {Observable<T>} Observable that emits the same notifications as the source Observable,\n * but with provided scheduler.\n *\n * @method observeOn\n * @owner Observable\n */\nexport function observeOn(scheduler, delay) {\n    if (delay === void 0) {\n        delay = 0;\n    }\n    return function observeOnOperatorFunction(source) {\n        return source.lift(new ObserveOnOperator(scheduler, delay));\n    };\n}\nvar ObserveOnOperator = /*@__PURE__*/ (function () {\n    function ObserveOnOperator(scheduler, delay) {\n        if (delay === void 0) {\n            delay = 0;\n        }\n        this.scheduler = scheduler;\n        this.delay = delay;\n    }\n    ObserveOnOperator.prototype.call = function (subscriber, source) {\n        return source.subscribe(new ObserveOnSubscriber(subscriber, this.scheduler, this.delay));\n    };\n    return ObserveOnOperator;\n}());\nexport { ObserveOnOperator };\n/**\n * We need this JSDoc comment for affecting ESDoc.\n * @ignore\n * @extends {Ignored}\n */\nvar ObserveOnSubscriber = /*@__PURE__*/ (function (_super) {\n    tslib_1.__extends(ObserveOnSubscriber, _super);\n    function ObserveOnSubscriber(destination, scheduler, delay) {\n        if (delay === void 0) {\n            delay = 0;\n        }\n        var _this = _super.call(this, destination) || this;\n        _this.scheduler = scheduler;\n        _this.delay = delay;\n        return _this;\n    }\n    /** @nocollapse */\n    ObserveOnSubscriber.dispatch = function (arg) {\n        var notification = arg.notification, destination = arg.destination;\n        notification.observe(destination);\n        this.unsubscribe();\n    };\n    ObserveOnSubscriber.prototype.scheduleMessage = function (notification) {\n        this.add(this.scheduler.schedule(ObserveOnSubscriber.dispatch, this.delay, new ObserveOnMessage(notification, this.destination)));\n    };\n    ObserveOnSubscriber.prototype._next = function (value) {\n        this.scheduleMessage(Notification.createNext(value));\n    };\n    ObserveOnSubscriber.prototype._error = function (err) {\n        this.scheduleMessage(Notification.createError(err));\n    };\n    ObserveOnSubscriber.prototype._complete = function () {\n        this.scheduleMessage(Notification.createComplete());\n    };\n    return ObserveOnSubscriber;\n}(Subscriber));\nexport { ObserveOnSubscriber };\nvar ObserveOnMessage = /*@__PURE__*/ (function () {\n    function ObserveOnMessage(notification, destination) {\n        this.notification = notification;\n        this.destination = destination;\n    }\n    return ObserveOnMessage;\n}());\nexport { ObserveOnMessage };\n//# sourceMappingURL=observeOn.js.map\n",null]}
