// AUTO-GENERATED DOCUMENTATION AND SERVICE
/**
 * Service Description: The Group API lets you inspect and manage your
 * [groups](#google.monitoring.v3.Group).
 *
 * <p>A group is a named filter that is used to identify a collection of monitored resources. Groups
 * are typically used to mirror the physical and/or logical topology of the environment. Because
 * group membership is computed dynamically, monitored resources that are started in the future are
 * automatically placed in matching groups. By using a group to name monitored resources in, for
 * example, an alert policy, the target of that alert policy is updated automatically as monitored
 * resources are added and removed from the infrastructure.
 *
 * <p>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:
 *
 * <pre>
 * <code>
 * try (GroupServiceClient groupServiceClient = GroupServiceClient.create()) {
 *   GroupName name = GroupName.of("[PROJECT]", "[GROUP]");
 *   Group response = groupServiceClient.getGroup(name);
 * }
 * </code>
 * </pre>
 *
 * <p>Note: close() needs to be called on the groupServiceClient object to clean up resources such
 * as threads. In the example above, try-with-resources is used, which automatically calls close().
 *
 * <p>The surface of this class includes several types of Java methods for each of the API's
 * methods:
 *
 * <ol>
 *   <li> 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.
 *   <li> 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.
 *   <li> 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.
 * </ol>
 *
 * <p>See the individual methods for example code.
 *
 * <p>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.
 *
 * <p>This class can be customized by passing in a custom instance of GroupServiceSettings to
 * create(). For example:
 *
 * <p>To customize credentials:
 *
 * <pre>
 * <code>
 * GroupServiceSettings groupServiceSettings =
 *     GroupServiceSettings.newBuilder()
 *         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
 *         .build();
 * GroupServiceClient groupServiceClient =
 *     GroupServiceClient.create(groupServiceSettings);
 * </code>
 * </pre>
 *
 * To customize the endpoint:
 *
 * <pre>
 * <code>
 * GroupServiceSettings groupServiceSettings =
 *     GroupServiceSettings.newBuilder().setEndpoint(myEndpoint).build();
 * GroupServiceClient groupServiceClient =
 *     GroupServiceClient.create(groupServiceSettings);
 * </code>
 * </pre>
