/**
 * Service Description: Manages external data source connections and credentials.
 *
 * 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:
 *
 * ```
 * $connectionServiceClient = new ConnectionServiceClient();
 * try {
 *     $formattedParent = $connectionServiceClient->locationName('[PROJECT]', '[LOCATION]');
 *     $connection = new Connection();
 *     $response = $connectionServiceClient->createConnection($formattedParent, $connection);
 * } finally {
 *     $connectionServiceClient->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.
 *
 * This service has a new (beta) implementation. See {@see
 * \Google\Cloud\BigQuery\Connection\V1\Client\ConnectionServiceClient} to use the
 * new surface.
