/**
 * Service Description: The Cloud Firestore Admin API.
 *
 * This API provides several administrative services for Cloud Firestore.
 *
 * Project, Database, Namespace, Collection, Collection Group, and Document are
 * used as defined in the Google Cloud Firestore API.
 *
 * Operation: An Operation represents work being performed in the background.
 *
 * The index service manages Cloud Firestore indexes.
 *
 * Index creation is performed asynchronously.
 * An Operation resource is created for each such asynchronous operation.
 * The state of the operation (including any errors encountered)
 * may be queried via the Operation resource.
 *
 * The Operations collection provides a record of actions performed for the
 * specified Project (including any Operations in progress). Operations are not
 * created directly but through calls on other collections or resources.
 *
 * An Operation that is done may be deleted so that it is no longer listed as
 * part of the Operation collection. Operations are garbage collected after
 * 30 days. By default, ListOperations will only return in progress and failed
 * operations. To list completed operation, issue a ListOperations request with
 * the filter `done: true`.
 *
 * Operations are created by service `FirestoreAdmin`, but are accessed via
 * service `google.longrunning.Operations`.
 *
 * This class provides the ability to make remote calls to the backing service through method
 * calls that map to API methods.
 *
 * 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.
