/**
 * Service Description: Google Cloud Management Service for Binary Authorization admission policies
 * and attestation authorities.
 *
 * This API implements a REST model with the following objects:
 *
 * * [Policy][google.cloud.binaryauthorization.v1beta1.Policy]
 * * [Attestor][google.cloud.binaryauthorization.v1beta1.Attestor]
 *
 * 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:
 *
 * ```
 * $binauthzManagementServiceV1Beta1Client = new BinauthzManagementServiceV1Beta1Client();
 * try {
 *     $formattedParent = $binauthzManagementServiceV1Beta1Client->projectName('[PROJECT]');
 *     $attestorId = 'attestor_id';
 *     $attestor = new Attestor();
 *     $response = $binauthzManagementServiceV1Beta1Client->createAttestor($formattedParent, $attestorId, $attestor);
 * } finally {
 *     $binauthzManagementServiceV1Beta1Client->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.
 *
