SDK schema: 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 — response body
| Field | Type | Presence | Description and constraints |
|---|---|---|---|
$ | object | Root | This resource represents a long-running operation that is the result of a network API call. |
done | boolean | Optional | 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. |
error | Model | Optional | Expand 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 — response body — error The error result of the operation in case of failure or cancellation. |
metadata | object | Optional | 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. Additional keys: see wildcard field |
metadata.* | JSON | Additional keys | Properties of the object. Contains field @type with type URL. |
name | string | Optional | 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}`. |
response | object | Optional | The normal, successful response of the operation. 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`. Additional keys: see wildcard field |
