Google Cloud Dataplex V1 Client - Class MetadataServiceClient (0.6.0)

Reference documentation and code samples for the Google Cloud Dataplex V1 Client class MetadataServiceClient.

Service Description: Metadata service manages metadata resources such as tables, filesets andpartitions.

This class provides the ability to make remote calls to the backing service through methodcalls that map to API methods. Sample code to get started:

$metadataServiceClient = new MetadataServiceClient();try {    $formattedParent = $metadataServiceClient->zoneName('[PROJECT]', '[LOCATION]', '[LAKE]', '[ZONE]');    $entity = new Entity();    $response = $metadataServiceClient->createEntity($formattedParent, $entity);} finally {    $metadataServiceClient->close();}

Many parameters require resource names to be formatted in a particular way. Toassist with these names, this class includes a format method for each type ofname, and additionally a parseName method to extract the individual identifierscontained within formatted names that are returned by the API.

This service has a new (beta) implementation. SeeGoogle\Cloud\Dataplex\V1\Client\MetadataServiceClient to use the new surface.

Methods

__construct

Constructor.

Parameters
NameDescription
optionsarray

Optional. Options for configuring the service API wrapper.

↳ apiEndpointstring

The address of the API remote host. May optionally include the port, formatted as "

↳ credentialsstring|array|FetchAuthTokenInterface|CredentialsWrapper

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-constructedGoogle\Auth\FetchAuthTokenInterface object orGoogle\ApiCore\CredentialsWrapper object. Note that when one of these objects are provided, any settings in $credentialsConfig will be ignored.

↳ credentialsConfigarray

Options used to configure credentials, including auth token caching, for the client. For a full list of supporting configuration options, seeGoogle\ApiCore\CredentialsWrapper::build() .

↳ disableRetriesbool

Determines whether or not retries defined by the client configuration should be disabled. Defaults tofalse.

↳ clientConfigstring|array

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.

↳ transportstring|TransportInterface

The transport used for executing network requests. May be either the stringrest orgrpc. Defaults togrpc if gRPC support is detected on the system.Advanced usage: Additionally, it is possible to pass in an already instantiatedGoogle\ApiCore\Transport\TransportInterface object. Note that when this object is provided, any settings in $transportConfig, and any $apiEndpoint setting, will be ignored.

↳ transportConfigarray

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 theGoogle\ApiCore\Transport\GrpcTransport::build() andGoogle\ApiCore\Transport\RestTransport::build() methods for the supported options.

↳ clientCertSourcecallable

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.

createEntity

Create a metadata entity.

optionalArgsarray

Optional.

↳ validateOnlybool

Optional. Only validate the request, but do not perform mutations. The default is false.
