/**
 * Service Description: This API allows users to manage their flat-rate BigQuery reservations.
 *
 * A reservation provides computational resource guarantees, in the form of
 * [slots](https://cloud.google.com/bigquery/docs/slots), to users. A slot is a
 * unit of computational power in BigQuery, and serves as the basic unit of
 * parallelism. In a scan of a multi-partitioned table, a single slot operates
 * on a single partition of the table. A reservation resource exists as a child
 * resource of the admin project and location, e.g.:
 * `projects/myproject/locations/US/reservations/reservationName`.
 *
 * A capacity commitment is a way to purchase compute capacity for BigQuery jobs
 * (in the form of slots) with some committed period of usage. A capacity
 * commitment resource exists as a child resource of the admin project and
 * location, e.g.:
 * `projects/myproject/locations/US/capacityCommitments/id`.
 *
 * 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:
 *
 * ```
 * $reservationServiceClient = new ReservationServiceClient();
 * try {
 *     $formattedParent = $reservationServiceClient->reservationName('[PROJECT]', '[LOCATION]', '[RESERVATION]');
 *     $response = $reservationServiceClient->createAssignment($formattedParent);
 * } finally {
 *     $reservationServiceClient->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.
