Class RegionInstancesClient (1.54.0)

GitHub RepositoryProduct Reference

Service Description: The RegionInstances 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 (RegionInstancesClient regionInstancesClient = RegionInstancesClient.create()) {
   String project = "project-309310695";
   String region = "region-934795532";
   BulkInsertInstanceResource bulkInsertInstanceResourceResource =
       BulkInsertInstanceResource.newBuilder().build();
   Operation response =
       regionInstancesClient
           .bulkInsertAsync(project, region, bulkInsertInstanceResourceResource)
           .get();
 }

Note: close() needs to be called on the RegionInstancesClient 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

BulkInsert

Creates multiple instances in a given region. Count specifies the number of instances to create.

Request object method variants only take one parameter, a request object, which must be constructed before the call.

  • bulkInsertAsync(BulkInsertRegionInstanceRequest request)

Methods that return long-running operations have "Async" method variants that return OperationFuture, which is used to track polling of the service.

  • bulkInsertAsync(String project, String region, BulkInsertInstanceResource bulkInsertInstanceResourceResource)

Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

  • bulkInsertOperationCallable()

  • bulkInsertCallable()

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 RegionInstancesSettings 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
 RegionInstancesSettings regionInstancesSettings =
     RegionInstancesSettings.newBuilder()
         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
         .build();
 RegionInstancesClient regionInstancesClient =
     RegionInstancesClient.create(regionInstancesSettings);

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
 RegionInstancesSettings regionInstancesSettings =
     RegionInstancesSettings.newBuilder().setEndpoint(myEndpoint).build();
 RegionInstancesClient regionInstancesClient =
     RegionInstancesClient.create(regionInstancesSettings);
