Class Operation (2.3.0)

This resource represents a long-running operation that is the result of a network API call.

If the value is false , it means the operation is still in progress. If true , the operation is completed, and either error or response is available.

The error result of the operation in case of failure or cancellation.

Service-specific metadata associated with the operation. It typically contains progress information and common metadata such as create time. Some services might not provide such metadata. Any method that returns a long-running operation should document the metadata type, if any.

The server-assigned name, which is only unique within the same service that originally returns it. If you use the default HTTP mapping, the name should be a resource name ending with operations/{unique_id} .

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 google.protobuf.Empty . If the original method is standard 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 is TakeSnapshot() , the inferred response type is TakeSnapshotResponse .
