/**
 * Service Description: A service for creating and managing Vertex AI's pipelines. This includes both
 * `TrainingPipeline` resources (used for AutoML and custom training) and
 * `PipelineJob` resources (used for Vertex AI Pipelines).
 *
 * 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:
 *
 * ```
 * $pipelineServiceClient = new PipelineServiceClient();
 * try {
 *     $formattedName = $pipelineServiceClient->pipelineJobName('[PROJECT]', '[LOCATION]', '[PIPELINE_JOB]');
 *     $pipelineServiceClient->cancelPipelineJob($formattedName);
 * } finally {
 *     $pipelineServiceClient->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.

     *           The syntax to define filter expression is based on

     *     @type int $pageSize
     *           The maximum number of resources contained in the underlying API
     *           response. The API may return fewer values in a page, even if
     *           there are additional values to be retrieved.
