Product Reference

Service Description: Manages services of an application.

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 (ServicesClient servicesClient = ServicesClient.create()) {
   GetServiceRequest request = GetServiceRequest.newBuilder().setName("name3373707").build();
   Service response = servicesClient.getService(request);
 }
 

Note: close() needs to be called on the ServicesClient 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
ListServices	Lists all the services in the application.	Request object method variants only take one parameter, a request object, which must be constructed before the call. listServices(ListServicesRequest request) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. listServicesPagedCallable() listServicesCallable()
GetService	Gets the current configuration of the specified service.	Request object method variants only take one parameter, a request object, which must be constructed before the call. getService(GetServiceRequest request) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. getServiceCallable()
UpdateService	Updates the configuration of the specified service.	Request object method variants only take one parameter, a request object, which must be constructed before the call. updateServiceAsync(UpdateServiceRequest request) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. updateServiceOperationCallable() updateServiceCallable()
DeleteService	Deletes the specified service and all enclosed versions.	Request object method variants only take one parameter, a request object, which must be constructed before the call. deleteServiceAsync(DeleteServiceRequest request) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. deleteServiceOperationCallable() deleteServiceCallable()

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 ServicesSettings 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
 ServicesSettings servicesSettings =
     ServicesSettings.newBuilder()
         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
         .build();
 ServicesClient servicesClient = ServicesClient.create(servicesSettings);
 

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
 ServicesSettings servicesSettings =
     ServicesSettings.newBuilder().setEndpoint(myEndpoint).build();
 ServicesClient servicesClient = ServicesClient.create(servicesSettings);
 

To use REST (HTTP1.1/JSON) transport (instead of gRPC) for sending and receiving requests over the wire:

 // 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
 ServicesSettings servicesSettings = ServicesSettings.newHttpJsonBuilder().build();
 ServicesClient servicesClient = ServicesClient.create(servicesSettings);
