Product Reference

Service Description: The RegionOperations API.

This class provides the ability to make remote calls to the backing service through method calls that map to API methods. Sample code to get started:

 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 try (RegionOperationsClient regionOperationsClient = RegionOperationsClient.create()) {
   String project = "project-309310695";
   String region = "region-934795532";
   String operation = "operation1662702951";
   DeleteRegionOperationResponse response =
       regionOperationsClient.delete(project, region, operation);
 }
 

Note: close() needs to be called on the RegionOperationsClient object to clean up resources such as threads. In the example above, try-with-resources is used, which automatically calls close().

Methods

Method	Description	Method Variants
Delete	Deletes the specified region-specific Operations resource.	Request object method variants only take one parameter, a request object, which must be constructed before the call. delete(DeleteRegionOperationRequest request) "Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method. delete(String project, String region, String operation) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. deleteCallable()
Get	Retrieves the specified region-specific Operations resource.	Request object method variants only take one parameter, a request object, which must be constructed before the call. get(GetRegionOperationRequest request) "Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method. get(String project, String region, String operation) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. getCallable()
List	Retrieves a list of Operation resources contained within the specified region.	Request object method variants only take one parameter, a request object, which must be constructed before the call. list(ListRegionOperationsRequest request) "Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method. list(String project, String region) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. listPagedCallable() listCallable()
Wait	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.	Request object method variants only take one parameter, a request object, which must be constructed before the call. wait(WaitRegionOperationRequest request) "Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method. wait(String project, String region, String operation) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. waitCallable()

See the individual methods for example code.

Many parameters require resource names to be formatted in a particular way. To assist with these names, this class includes a format method for each type of name, and additionally a parse method to extract the individual identifiers contained within names that are returned.

This class can be customized by passing in a custom instance of RegionOperationsSettings to create(). For example:

To customize credentials:

 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 RegionOperationsSettings regionOperationsSettings =
     RegionOperationsSettings.newBuilder()
         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
         .build();
 RegionOperationsClient regionOperationsClient =
     RegionOperationsClient.create(regionOperationsSettings);
 

To customize the endpoint:

 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 RegionOperationsSettings regionOperationsSettings =
     RegionOperationsSettings.newBuilder().setEndpoint(myEndpoint).build();
 RegionOperationsClient regionOperationsClient =
     RegionOperationsClient.create(regionOperationsSettings);

wait(WaitRegionOperationRequest request)

public final Operation wait(WaitRegionOperationRequest request)

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.

Sample code:

 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
