// AUTO-GENERATED DOCUMENTATION AND SERVICE
/**
 * Service Description: Configures and manages Cloud Memorystore for Redis instances
 *
 * <p>Google Cloud Memorystore for Redis v1beta1
 *
 * <p>The `redis.googleapis.com` service implements the Google Cloud Memorystore for Redis API and
 * defines the following resource model for managing Redis instances: &#42; The service works with a
 * collection of cloud projects, named: `/projects/&#42;` &#42; Each project has a collection of
 * available locations, named: `/locations/&#42;` &#42; Each location has a collection of Redis
 * instances, named: `/instances/&#42;` &#42; As such, Redis instances are resources of the form:
 * `/projects/{project_id}/locations/{location_id}/instances/{instance_id}`
 *
 * <p>Note that location_id must be refering to a GCP `region`; for example: &#42;
 * `projects/redpepper-1290/locations/us-central1/instances/my-redis`
 *
 * <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 (CloudRedisClient cloudRedisClient = CloudRedisClient.create()) {
 *   InstanceName name = InstanceName.of("[PROJECT]", "[LOCATION]", "[INSTANCE]");
 *   Instance response = cloudRedisClient.getInstance(name);
 * }
 * </code>
 * </pre>
 *
 * <p>Note: close() needs to be called on the cloudRedisClient 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 CloudRedisSettings to
 * create(). For example:
 *
 * <p>To customize credentials:
 *
 * <pre>
 * <code>
 * CloudRedisSettings cloudRedisSettings =
 *     CloudRedisSettings.newBuilder()
 *         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
 *         .build();
 * CloudRedisClient cloudRedisClient =
 *     CloudRedisClient.create(cloudRedisSettings);
 * </code>
 * </pre>
 *
 * To customize the endpoint:
 *
 * <pre>
 * <code>
 * CloudRedisSettings cloudRedisSettings =
 *     CloudRedisSettings.newBuilder().setEndpoint(myEndpoint).build();
 * CloudRedisClient cloudRedisClient =
 *     CloudRedisClient.create(cloudRedisSettings);
 * </code>
 * </pre>
