/**
 * Service Description: Secret Manager Service
 *
 * Manages secrets and operations using those secrets. Implements a REST
 * model with the following objects:
 *
 * * [Secret][google.cloud.secrets.v1beta1.Secret]
 * * [SecretVersion][google.cloud.secrets.v1beta1.SecretVersion]
 *
 * 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:
 *
 * ```
 * $secretManagerServiceClient = new SecretManagerServiceClient();
 * try {
 *     $formattedName = $secretManagerServiceClient->secretVersionName('[PROJECT]', '[SECRET]', '[SECRET_VERSION]');
 *     $response = $secretManagerServiceClient->accessSecretVersion($formattedName);
 * } finally {
 *     $secretManagerServiceClient->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.
 *
