Description:
 def get_operation( self, name, retry=gapic_v1.method.DEFAULT, timeout=gapic_v1.method.DEFAULT ):
 """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. Example: Args: name (str):
 The name of the operation resource. retry (google.api_core.retry.Retry):
 The retry strategy to use when invoking the RPC. If unspecified, the default retry from the client configuration will be used. If ``None``, then this method will not retry the RPC at all. timeout (float):
 The amount of time in seconds to wait for the RPC to complete. Note that if ``retry`` is used, this timeout applies to each individual attempt and the overall time it takes for this method to complete may be longer. If unspecified, the the default timeout in the client configuration is used. If ``None``, then the RPC method will not time out. Returns: google.longrunning.operations_pb2.Operation: The state of the operation. Raises: google.api_core.exceptions.GoogleAPICallError: If an error occurred while invoking the RPC, the appropriate ``GoogleAPICallError`` subclass will be raised. """
