Class ServicesClient (0.1.2)

public class ServicesClient implements BackgroundResource

Service Description: Cloud Run Service Control Plane 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:


 try (ServicesClient servicesClient = ServicesClient.create()) {
   ServiceName name = ServiceName.of("[PROJECT]", "[LOCATION]", "[SERVICE]");
   Service response = servicesClient.getService(name);
 }
 

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().

The surface of this class includes several types of Java methods for each of the API's methods:

  1. A "flattened" method. With this type of method, the fields of the request type have been converted into function parameters. It may be the case that not all fields are available as parameters, and not every API method will have a flattened method entry point.
  2. A "request object" method. This type of method only takes one parameter, a request object, which must be constructed before the call. Not every API method will have a request object method.
  3. A "callable" method. This type of method takes no parameters and returns an immutable API callable object, which can be used to initiate calls to the service.

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:


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

To customize the endpoint:


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