     * Constructor.
     *
     * @param array $options {
     *     Optional. Options for configuring the service API wrapper.
     *
     *     @type string $apiEndpoint
     *           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
     *           {@see \Google\ApiCore\CredentialsWrapper} object. Note that when one of these
     *           objects are provided, any settings in $credentialsConfig will be ignored.
     *           *Important*: If you accept a credential configuration (credential
     *           JSON/File/Stream) from an external source for authentication to Google Cloud
     *           Platform, you must validate it before providing it to any Google API or library.
     *           Providing an unvalidated credential configuration to Google APIs can compromise
     *           the security of your systems and data. For more information {@see
     *           https://cloud.google.com/docs/authentication/external/externally-sourced-credentials}
     *     @type array $credentialsConfig
     *           Options used to configure credentials, including auth token caching, for the
     *           client. For a full list of supporting configuration options, see
     *           {@see \Google\ApiCore\CredentialsWrapper::build()} .
     *     @type bool $disableRetries
     *           Determines whether or not retries defined by the client configuration should be
     *           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
     *           instantiated {@see \Google\ApiCore\Transport\TransportInterface} object. Note
     *           that when this object is provided, any settings in $transportConfig, and any
     *           $apiEndpoint setting, will be ignored.
     *     @type array $transportConfig
     *           Configuration options that will be used to construct the transport. Options for
     *           each supported transport type should be passed in a key for that transport. For
     *           example:
     *           $transportConfig = [
     *               'grpc' => [...],
     *               'rest' => [...],
     *           ];
     *           See the {@see \Google\ApiCore\Transport\GrpcTransport::build()} and
     *           {@see \Google\ApiCore\Transport\RestTransport::build()} methods for the
     *           supported options.
     *     @type callable $clientCertSource
     *           A callable which returns the client cert as a string. This can be used to
     *           provide a certificate and private key to the transport layer for mTLS.
     *     @type false|LoggerInterface $logger
     *           A PSR-3 compliant logger. If set to false, logging is disabled, ignoring the
     *           'GOOGLE_SDK_PHP_LOGGING' environment flag
     * }
