/**
 * Service Description: The IDS Service
 *
 * 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:
 *
 * ```
 * $iDSClient = new IDSClient();
 * try {
 *     $formattedParent = $iDSClient->locationName('[PROJECT]', '[LOCATION]');
 *     $endpointId = 'endpoint_id';
 *     $endpoint = new Endpoint();
 *     $operationResponse = $iDSClient->createEndpoint($formattedParent, $endpointId, $endpoint);
 *     $operationResponse->pollUntilComplete();
 *     if ($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 = $iDSClient->createEndpoint($formattedParent, $endpointId, $endpoint);
 *     $operationName = $operationResponse->getName();
 *     // ... do other work
 *     $newOperationResponse = $iDSClient->resumeOperation($operationName, 'createEndpoint');
 *     while (!$newOperationResponse->isDone()) {
 *         // ... do other work
 *         $newOperationResponse->reload();
 *     }
 *     if ($newOperationResponse->operationSucceeded()) {
 *         $result = $newOperationResponse->getResult();
 *     // doSomethingWith($result)
 *     } else {
 *         $error = $newOperationResponse->getError();
 *         // handleError($error)
 *     }
 * } finally {
 *     $iDSClient->close();
 * }
 * ```
 *
 * 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 parseName method to extract the individual identifiers
 * contained within formatted names that are returned by the API.

     *           An optional request ID to identify requests. Specify a unique request ID
     *           so that if you must retry your request, the server will know to ignore
     *           the request if it has already been completed. The server will guarantee
     *           that for at least 60 minutes after the first request.
     *
     *           For example, consider a situation where you make an initial request and t
     *           he request times out. If you make the request again with the same request
     *           ID, the server can check if original operation with the same request ID
     *           was received, and if so, will ignore the second request. This prevents
     *           clients from accidentally creating duplicate commitments.
     *
     *           The request ID must be a valid UUID with the exception that zero UUID is
