/**
 * Service Description: Provides a method to create and modify Google Cloud Dataflow jobs.
 * A Job is a multi-stage computation graph run by the Cloud Dataflow 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:
 *
 * ```
 * $jobsV1Beta3Client = new JobsV1Beta3Client();
 * try {
 *     // Iterate over pages of elements
 *     $pagedResponse = $jobsV1Beta3Client->aggregatedListJobs();
 *     foreach ($pagedResponse->iteratePages() as $page) {
 *         foreach ($page as $element) {
 *             // doSomethingWith($element);
 *         }
 *     }
 *     // Alternatively:
 *     // Iterate through all elements
 *     $pagedResponse = $jobsV1Beta3Client->aggregatedListJobs();
 *     foreach ($pagedResponse->iterateAllElements() as $element) {
 *         // doSomethingWith($element);
 *     }
 * } finally {
 *     $jobsV1Beta3Client->close();
 * }

     *           The address of the API remote host. May optionally include the port, formatted
     *           as "<uri>:<port>". Default 'dataflow.googleapis.com:443'.
     *     @type string|array|FetchAuthTokenInterface|CredentialsWrapper $credentials
     *           The credentials to be used by the client to authorize API calls. This option
     *           accepts either a path to a credentials file, or a decoded credentials file as a
     *           PHP array.
     *           *Advanced usage*: In addition, this option can also accept a pre-constructed
     *           {@see \Google\Auth\FetchAuthTokenInterface} object or

     *           disabled. Defaults to `false`.
     *     @type string|array $clientConfig
     *           Client method configuration, including retry settings. This option can be either
     *           a path to a JSON file, or a PHP array containing the decoded JSON data. By
     *           default this settings points to the default client config file, which is
     *           provided in the resources folder.
     *     @type string|TransportInterface $transport
     *           The transport used for executing network requests. May be either the string
     *           `rest` or `grpc`. Defaults to `grpc` if gRPC support is detected on the system.
     *           *Advanced usage*: Additionally, it is possible to pass in an already

     * List the jobs of a project.
     *
     * To list the jobs of a project in a region, we recommend using
     * `projects.locations.jobs.list` with a [regional endpoint]
     * (https://cloud.google.com/dataflow/docs/concepts/regional-endpoints). To
     * list the all jobs across all regions, use `projects.jobs.aggregated`. Using
     * `projects.jobs.list` is not recommended, as you can only get the list of
     * jobs that are running in `us-central1`.
     *
     * Sample code:
     * ```
     * $jobsV1Beta3Client = new JobsV1Beta3Client();
     * try {
     *     // Iterate over pages of elements
     *     $pagedResponse = $jobsV1Beta3Client->listJobs();
     *     foreach ($pagedResponse->iteratePages() as $page) {
     *         foreach ($page as $element) {
     *             // doSomethingWith($element);
     *         }
     *     }
     *     // Alternatively:
     *     // Iterate through all elements
     *     $pagedResponse = $jobsV1Beta3Client->listJobs();
