/**
 * Service Description: Service for configuring sinks used to export log entries out of
 * Logging.
 *
 * 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:
 *
 * ```
 * $configServiceV2Client = new ConfigServiceV2Client();
 * try {
 *     $formattedParent = $configServiceV2Client->projectName('[PROJECT]');
 *     // Iterate over pages of elements
 *     $pagedResponse = $configServiceV2Client->listSinks($formattedParent);
 *     foreach ($pagedResponse->iteratePages() as $page) {
 *         foreach ($page as $element) {
 *             // doSomethingWith($element);
 *         }
 *     }
 *
 *
 *     // Alternatively:
 *
 *     // Iterate through all elements
 *     $pagedResponse = $configServiceV2Client->listSinks($formattedParent);
 *     foreach ($pagedResponse->iterateAllElements() as $element) {
 *         // doSomethingWith($element);
 *     }
 * } finally {
 *     $configServiceV2Client->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.
