/**
 * Service Description: API v1beta1 service for Cloud AI Platform Notebooks.
 *
 * 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:
 *
 * ```
 * $notebookServiceClient = new NotebookServiceClient();
 * try {
 *     $parent = 'parent';
 *     $environmentId = 'environment_id';
 *     $environment = new Environment();
 *     $operationResponse = $notebookServiceClient->createEnvironment($parent, $environmentId, $environment);
 *     $operationResponse->pollUntilComplete();
 *     if ($operationResponse->operationSucceeded()) {
 *         $result = $operationResponse->getResult();
 *     // doSomethingWith($result)
 *     } else {
 *         $error = $operationResponse->getError();
 *         // handleError($error)
 *     }
 *     // Alternatively:
 *     // start the operation, keep the operation name, and resume later
 *     $operationResponse = $notebookServiceClient->createEnvironment($parent, $environmentId, $environment);
 *     $operationName = $operationResponse->getName();
 *     // ... do other work
 *     $newOperationResponse = $notebookServiceClient->resumeOperation($operationName, 'createEnvironment');
 *     while (!$newOperationResponse->isDone()) {
 *         // ... do other work
 *         $newOperationResponse->reload();
 *     }
 *     if ($newOperationResponse->operationSucceeded()) {
 *         $result = $newOperationResponse->getResult();
 *     // doSomethingWith($result)
 *     } else {
 *         $error = $newOperationResponse->getError();
 *         // handleError($error)
 *     }
 * } finally {
 *     $notebookServiceClient->close();
 * }
 * ```
 *
 * Many parameters require resource names to be formatted in a particular way. To
 * assistwith these names, this class includes a format method for each type of
 * name, and additionallya parseName method to extract the individual identifiers
 * contained within formatted namesthat are returned by the API.
