// AUTO-GENERATED DOCUMENTATION AND SERVICE
/**
 * Service Description: An intent represents a mapping between input from a user and an action to be
 * taken by your application. When you pass user input to the
 * [DetectIntent][google.cloud.dialogflow.v2.Sessions.DetectIntent] (or
 * [StreamingDetectIntent][google.cloud.dialogflow.v2.Sessions.StreamingDetectIntent]) method, the
 * Dialogflow API analyzes the input and searches for a matching intent. If no match is found, the
 * Dialogflow API returns a fallback intent (`is_fallback` = true).
 *
 * <p>You can provide additional information for the Dialogflow API to use to match user input to an
 * intent by adding the following to your intent.
 *
 * <p>&#42; &#42;&#42;Contexts&#42;&#42; - provide additional context for intent analysis. For
 * example, if an intent is related to an object in your application that plays music, you can
 * provide a context to determine when to match the intent if the user input is “turn it off”. You
 * can include a context that matches the intent when there is previous user input of "play music",
 * and not when there is previous user input of "turn on the light".
 *
 * <p>&#42; &#42;&#42;Events&#42;&#42; - allow for matching an intent by using an event name instead
 * of user input. Your application can provide an event name and related parameters to the
 * Dialogflow API to match an intent. For example, when your application starts, you can send a
 * welcome event with a user name parameter to the Dialogflow API to match an intent with a
 * personalized welcome message for the user.
 *
 * <p>&#42; &#42;&#42;Training phrases&#42;&#42; - provide examples of user input to train the
 * Dialogflow API agent to better match intents.
 *
 * <p>For more information about intents, see the [Dialogflow
 * documentation](https://dialogflow.com/docs/intents).
 *
 * <p>This class provides the ability to make remote calls to the backing service through method
 * calls that map to API methods. Sample code to get started:
 *
 * <pre>
 * <code>
 * try (IntentsClient intentsClient = IntentsClient.create()) {
 *   IntentName name = IntentName.of("[PROJECT]", "[INTENT]");
 *   Intent response = intentsClient.getIntent(name);
 * }
 * </code>
 * </pre>
 *
 * <p>Note: close() needs to be called on the intentsClient object to clean up resources such as
 * threads. In the example above, try-with-resources is used, which automatically calls close().
 *
 * <p>The surface of this class includes several types of Java methods for each of the API's
 * methods:
 *
 * <ol>
 *   <li> A "flattened" method. With this type of method, the fields of the request type have been
 *       converted into function parameters. It may be the case that not all fields are available as
 *       parameters, and not every API method will have a flattened method entry point.
 *   <li> A "request object" method. This type of method only takes one parameter, a request object,
 *       which must be constructed before the call. Not every API method will have a request object
 *       method.
 *   <li> A "callable" method. This type of method takes no parameters and returns an immutable API
 *       callable object, which can be used to initiate calls to the service.
 * </ol>
 *
 * <p>See the individual methods for example code.
 *
 * <p>Many parameters require resource names to be formatted in a particular way. To assist with
 * these names, this class includes a format method for each type of name, and additionally a parse
 * method to extract the individual identifiers contained within names that are returned.
 *
 * <p>This class can be customized by passing in a custom instance of IntentsSettings to create().
 * For example:
 *
 * <p>To customize credentials:
 *
 * <pre>
 * <code>
 * IntentsSettings intentsSettings =
 *     IntentsSettings.newBuilder()
 *         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
 *         .build();
 * IntentsClient intentsClient =
 *     IntentsClient.create(intentsSettings);
 * </code>
 * </pre>
 *
 * To customize the endpoint:
 *
 * <pre>
 * <code>
 * IntentsSettings intentsSettings =
 *     IntentsSettings.newBuilder().setEndpoint(myEndpoint).build();
 * IntentsClient intentsClient =
 *     IntentsClient.create(intentsSettings);
 * </code>
 * </pre>
