## Instance Methods

Retrieves an aggregated list of all operations.

Retrieves the next page of results.

Close httplib2 connections.

Deletes the specified Operations resource.

Retrieves the specified Operations resource.

Retrieves a list of Operation resources contained within the specified project.

Retrieves the next page of results.

Waits for the specified Operation resource to return as `DONE` or for the request to approach the 2 minute deadline, and retrieves the specified Operation resource. This method differs from the `GET` method in that it waits for no more than the default deadline (2 minutes) and then returns the current state of the operation, which might be `DONE` or still in progress. This method is called on a best-effort basis. Specifically: - In uncommon cases, when the server is overloaded, the request might return before the default deadline is reached, or might return after zero seconds. - If the default deadline is reached, there is no guarantee that the operation is actually done when the method returns. Be prepared to retry if the operation is not `DONE`.

### Method Details

`aggregatedList(project, filter=None, includeAllScopes=None, maxResults=None, orderBy=None, pageToken=None, returnPartialSuccess=None, x__xgafv=None)`

    Retrieves an aggregated list of all operations.

    Args:
      project: string, Project ID for this request. (required)
      filter: string, A filter expression that filters resources listed in the response. The expression must specify the field name, an operator, and the value that you want to use for filtering. The value must be a string, a number, or a boolean. The operator must be either `=`, `!=`, `>`, `<`, `<=`, `>=` or `:`. For example, if you are filtering Compute Engine instances, you can exclude instances named `example-instance` by specifying `name != example-instance`. The `:` operator can be used with string fields to match substrings. For non-string fields it is equivalent to the `=` operator. The `:*` comparison can be used to test whether a key has been defined. For example, to find all objects with `owner` label use: ``` labels.owner:* ``` You can also filter nested fields. For example, you could specify `scheduling.automaticRestart = false` to include instances only if they are not scheduled for automatic restarts. You can use filtering on nested fields to filter based on resource labels. To filter on multiple expressions, provide each separate expression within parentheses. For example: ``` (scheduling.automaticRestart = true) (cpuPlatform = "Intel Skylake") ``` By default, each expression is an `AND` expression. However, you can include `AND` and `OR` expressions explicitly. For example: ``` (cpuPlatform = "Intel Skylake") OR (cpuPlatform = "Intel Broadwell") AND (scheduling.automaticRestart = true) ```
      includeAllScopes: boolean, Indicates whether every visible scope for each scope type (zone, region, global) should be included in the response. For new resource types added after this field, the flag has no effect as new resource types will always include every visible scope for each scope type in response. For resource types which predate this field, if this flag is omitted or false, only scopes of the scope types where the resource type is expected to be found will be included.
      maxResults: integer, The maximum number of results per page that should be returned. If the number of available results is larger than `maxResults`, Compute Engine returns a `nextPageToken` that can be used to get the next page of results in subsequent list requests. Acceptable values are `0` to `500`, inclusive. (Default: `500`)
      orderBy: string, Sorts list results by a certain order. By default, results are returned in alphanumerical order based on the resource name. You can also sort results in descending order based on the creation timestamp using `orderBy="creationTimestamp desc"`. This sorts results based on the `creationTimestamp` field in reverse chronological order (newest result first). Use this to sort resources like operations so that the newest operation is returned first. Currently, only sorting by `name` or `creationTimestamp desc` is supported.
      pageToken: string, Specifies a page token to use. Set `pageToken` to the `nextPageToken` returned by a previous list request to get the next page of results.
      returnPartialSuccess: boolean, Opt-in for partial success behavior which provides partial results in case of failure. The default value is false.
      x__xgafv: string, V1 error format.
        Allowed values
          1 - v1 error format
          2 - v2 error format

`list_next(previous_request, previous_response)`

    Retrieves the next page of results.

    Args:
      previous_request: The request for the previous page. (required)
      previous_response: The response from the request for the previous page. (required)

    Returns:
      A request object that you can call 'execute()' on to request the next
      page. Returns None if there are no more items in the collection.

`wait(project, operation, x__xgafv=None)`

    Waits for the specified Operation resource to return as `DONE` or for the request to approach the 2 minute deadline, and retrieves the specified Operation resource. This method differs from the `GET` method in that it waits for no more than the default deadline (2 minutes) and then returns the current state of the operation, which might be `DONE` or still in progress. This method is called on a best-effort basis. Specifically: - In uncommon cases, when the server is overloaded, the request might return before the default deadline is reached, or might return after zero seconds. - If the default deadline is reached, there is no guarantee that the operation is actually done when the method returns. Be prepared to retry if the operation is not `DONE`.

    Args:
      project: string, Project ID for this request. (required)
      operation: string, Name of the Operations resource to return. (required)
      x__xgafv: string, V1 error format.
        Allowed values
          1 - v1 error format
          2 - v2 error format

    Returns:
      An object of the form:

        { # Represents an Operation resource. Google Compute Engine has three Operation resources: * [Global](/compute/docs/reference/rest/beta/globalOperations) * [Regional](/compute/docs/reference/rest/beta/regionOperations) * [Zonal](/compute/docs/reference/rest/beta/zoneOperations) You can use an operation resource to manage asynchronous API requests. For more information, read Handling API responses. Operations can be global, regional or zonal. - For global operations, use the `globalOperations` resource. - For regional operations, use the `regionOperations` resource. - For zonal operations, use the `zonalOperations` resource. For more information, read Global, Regional, and Zonal Resources.
