### Method Details

`cancel(name, x__xgafv=None)`

    Cancels a transfer. Use the get method to check whether the cancellation succeeded or whether the operation completed despite cancellation.

    Args:
      name: string, The name of the operation resource to be cancelled. (required)
      x__xgafv: string, V1 error format.
        Allowed values
          1 - v1 error format
          2 - v2 error format

    Returns:
      An object of the form:

        { # A generic empty message that you can re-use to avoid defining duplicated
          # empty messages in your APIs. A typical example is to use it as the request
          # or the response type of an API method. For instance:
          #
          #     service Foo {
          #       rpc Bar(google.protobuf.Empty) returns (google.protobuf.Empty);
          #     }
          #
          # The JSON representation for `Empty` is empty JSON object `{}`.
      }

`get(name, x__xgafv=None)`

    Gets the latest state of a long-running operation.  Clients can use this
    method to poll the operation result at intervals as recommended by the API
    service.

    Args:
      name: string, The name of the operation resource. (required)
      x__xgafv: string, V1 error format.
        Allowed values
          1 - v1 error format
          2 - v2 error format

    Returns:
      An object of the form:

          # network API call.

        },
        "done": True or False, # If the value is `false`, it means the operation is still in progress.

            # available.
        "response": { # The normal response of the operation in case of success.  If the original
            # method returns no data on success, such as `Delete`, the response is

            # `Get`/`Create`/`Update`, the response should be the resource.  For other
            # methods, the response should have the type `XxxResponse`, where `Xxx`
            # is the original method name.  For example, if the original method name

`list(name, filter=None, pageToken=None, pageSize=None, x__xgafv=None)`

    Lists transfer operations.

    Args:
      name: string, Required. The value `transferOperations`. (required)
      filter: string, Required. A list of query parameters specified as JSON text in the form of: {"project<span>_</span>id":"my_project_id",
     "job_names":["jobid1","jobid2",...],
     "operation_names":["opid1","opid2",...],
     "transfer_statuses":["status1","status2",...]}.
    Since `job_names`, `operation_names`, and `transfer_statuses` support multiple values, they must be specified with array notation. `project`<span>`_`</span>`id` is required. `job_names`, `operation_names`, and `transfer_statuses` are optional. The valid values for `transfer_statuses` are case-insensitive: IN_PROGRESS, PAUSED, SUCCESS, FAILED, and ABORTED.
      pageToken: string, The list page token.
      pageSize: integer, The list page size. The max allowed value is 256.
      x__xgafv: string, V1 error format.
        Allowed values
          1 - v1 error format
          2 - v2 error format
