/**
 * Service Description: This API allows users to manage their data transfers into BigQuery.
 *
 * 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:
 *
 * ```
 * $dataTransferServiceClient = new DataTransferServiceClient();
 * try {
 *     $formattedName = $dataTransferServiceClient->dataSourceName('[PROJECT]', '[DATA_SOURCE]');
 *     $response = $dataTransferServiceClient->checkValidCreds($formattedName);
 * } finally {
 *     $dataTransferServiceClient->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.
