+ * 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.
+ *
+ * This class is currently experimental and may be subject to changes.

+/**
+ * Service Description: Configures and manages metastore services.
+ * Metastore services are fully managed, highly available, autoscaled,
+ * autohealing, OSS-native deployments of technical metadata management
+ * software. Each metastore service exposes a network endpoint through which
+ * metadata queries are served. Metadata queries can originate from a variety
+ * of sources, including Apache Hive, Apache Presto, and Apache Spark.
+ *
+ * The Dataproc Metastore API defines the following resource model:
+ *
+ * * The service works with a collection of Google Cloud projects, named:
+ * `/projects/*`
+ * * Each project has a collection of available locations, named: `/locations/*`
+ * (a location must refer to a Google Cloud `region`)
+ * * Each location has a collection of services, named: `/services/*`
+ * * Dataproc Metastore services are resources with names of the form:
+ *
+ * `/projects/{project_number}/locations/{location_id}/services/{service_id}`.
+ *
+ * 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.
+ *
+ * This class is currently experimental and may be subject to changes.

+/**
+ * Service Description: Configures and manages metastore federation services.
+ * Dataproc Metastore Federation Service allows federating a collection of
+ * backend metastores like BigQuery, Dataplex Lakes, and other Dataproc
+ * Metastores. The Federation Service exposes a gRPC URL through which metadata
+ * from the backend metastores are served at query time.
+ *
+ * The Dataproc Metastore Federation API defines the following resource model:
+ * * The service works with a collection of Google Cloud projects.
+ * * Each project has a collection of available locations.
+ * * Each location has a collection of federations.
+ * * Dataproc Metastore Federations are resources with names of the
+ * form:
+ * `projects/{project_number}/locations/{location_id}/federations/{federation_id}`.
+ *
+ * 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.
+ *
+ * This class is currently experimental and may be subject to changes.
+ *

+ * EntityFilter: Allows specifying a subset of entities in a project. This is
+ * specified as a combination of kinds and namespaces (either or both of which
+ * may be all).
+ *
+ * -----------------------------------------------------------------------------
+ * ## Services
+ *
+ * # Export/Import
+ *
+ * The Export/Import service provides the ability to copy all or a subset of
+ * entities to/from Google Cloud Storage.
+ *
+ * Exported data may be imported into Cloud Datastore for any Google Cloud
+ * Platform project. It is not restricted to the export source project. It is
+ * possible to export from one project and then import into another.
+ *
+ * Exported data can also be loaded into Google BigQuery for analysis.
+ *
+ * Exports and imports are performed asynchronously. An Operation resource is
+ * created for each export/import. The state (including any errors encountered)
+ * of the export/import may be queried via the Operation resource.
+ *
+ * # Index
+ *
+ * The index service manages Cloud Datastore composite indexes.
+ *
+ * Index creation and deletion are 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.
+ *
+ * # Operation
+ *
+ * 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 not yet done may be cancelled. The request to cancel is
+ * asynchronous and the operation may continue to run for some time after the
+ * request to cancel is made.
+ *
+ * An operation that is done may be deleted so that it is no longer listed as
+ * part of the Operation collection.
+ *
+ * ListOperations returns all pending operations, but not completed operations.
+ *
+ * Operations are created by service DatastoreAdmin,
+ * 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.
+ *
+ * This class is currently experimental and may be subject to changes.

+ * 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.
+ *
+ * This class is currently experimental and may be subject to changes.

+/**
+ * Service Description: Eventarc processes events generated by an event provider and delivers them to
+ * a subscriber.
+ *
+ * An event provider is a software-as-a-service (SaaS) system or
+ * product that can generate and deliver events through Eventarc.
+ *
+ * A third-party event provider is an event provider from outside of Google.
+ *
+ * A partner is a third-party event provider that is integrated with Eventarc.
+ *
+ * A subscriber is a GCP customer interested in receiving events.
+ *
+ * Channel is a first-class Eventarc resource that is created and managed
+ * by the subscriber in their GCP project. A Channel represents a subscriber's
+ * intent to receive events from an event provider. A Channel is associated with
+ * exactly one event provider.
+ *
+ * ChannelConnection is a first-class Eventarc resource that
+ * is created and managed by the partner in their GCP project. A
+ * ChannelConnection represents a connection between a partner and a
+ * subscriber's Channel. A ChannelConnection has a one-to-one mapping with a
+ * Channel.
+ *
+ * Publisher allows an event provider to publish events to Eventarc.
+ *
+ * This class provides the ability to make remote calls to the backing service through method
+ * calls that map to API methods.
+ *
+ * This class is currently experimental and may be subject to changes.

+/**
+ * Service Description: A service for managing Google Workspace Add-ons deployments.
+ *
+ * A Google Workspace Add-on is a third-party embedded component that can be
+ * installed in Google Workspace Applications like Gmail, Calendar, Drive, and
+ * the Google Docs, Sheets, and Slides editors. Google Workspace Add-ons can
+ * display UI cards, receive contextual information from the host application,
+ * and perform actions in the host application (See:
+ * https://developers.google.com/gsuite/add-ons/overview for more information).
+ *
+ * A Google Workspace Add-on deployment resource specifies metadata about the
+ * add-on, including a specification of the entry points in the host application
+ * that trigger add-on executions (see:
+ * https://developers.google.com/gsuite/add-ons/concepts/gsuite-manifests).
+ * Add-on deployments defined via the Google Workspace Add-ons API define their
+ * entrypoints using HTTPS URLs (See:
+ * https://developers.google.com/gsuite/add-ons/guides/alternate-runtimes),
+ *
+ * A Google Workspace Add-on deployment can be installed in developer mode,
+ * which allows an add-on developer to test the experience an end-user would see
+ * when installing and running the add-on in their G Suite applications.  When
+ * running in developer mode, more detailed error messages are exposed in the
+ * add-on UI to aid in debugging.
+ *
+ * A Google Workspace Add-on deployment can be published to Google Workspace
+ * Marketplace, which allows other Google Workspace users to discover and
+ * install the add-on.  See:
+ * https://developers.google.com/gsuite/add-ons/how-tos/publish-add-on-overview
+ * for details.
+ *
+ * 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.
+ *
+ * This class is currently experimental and may be subject to changes.
+ *

+ * Service Description: BackupForGKE allows Kubernetes administrators to configure, execute, and
+ * manage backup and restore operations for their GKE clusters.
+ *
+ * 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.
+ *
+ * This class is currently experimental and may be subject to changes.

+/**
+ * Service Description: The AttachedClusters API provides a single centrally managed service
+ * to register and manage Anthos attached clusters that run on customer's owned
+ * infrastructure.
+ *
+ * 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.
+ *
+ * This class is currently experimental and may be subject to changes.

+ * Service Description: The AwsClusters API provides a single centrally managed service
+ * to create and manage Anthos clusters that run on AWS infrastructure.
+ *
+ * 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.
+ *
+ * This class is currently experimental and may be subject to changes.

+ * 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.
+ *
+ * This class is currently experimental and may be subject to changes.

+/**
+ * Service Description: [Grafeas](https://grafeas.io) API.
+ *
+ * Retrieves analysis results of Cloud components such as Docker container
+ * images.
+ *
+ * Analysis results are stored as a series of occurrences. An `Occurrence`
+ * contains information about a specific analysis instance on a resource. An
+ * occurrence refers to a `Note`. A note contains details describing the
+ * analysis and is generally stored in a separate project, called a `Provider`.
+ * Multiple occurrences can refer to the same note.
+ *
+ * For example, an SSL vulnerability could affect multiple images. In this case,
+ * there would be one note for the vulnerability and an occurrence for each
+ * image with the vulnerability referring to that note.
+ *
+ * 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.
+ *
+ * This class is currently experimental and may be subject to changes.

+     *     @type string|TransportInterface $transport
+     *           The transport used for executing network requests. May be either the string
+     *           `rest` or `grpc`. Defaults to `grpc` if gRPC support is detected on the system.
+     *           *Advanced usage*: Additionally, it is possible to pass in an already

+/**
+ * Service Description: An interface for managing organization policies.
+ *
+ * The Cloud Org Policy service provides a simple mechanism for organizations to
+ * restrict the allowed configurations across their entire Cloud Resource
+ * hierarchy.
+ *
+ * You can use a `policy` to configure restrictions in Cloud resources. For
+ * example, you can enforce a `policy` that restricts which Google
+ * Cloud Platform APIs can be activated in a certain part of your resource
+ * hierarchy, or prevents serial port access to VM instances in a particular
+ * folder.
+ *
+ * `Policies` are inherited down through the resource hierarchy. A `policy`
+ * applied to a parent resource automatically applies to all its child resources
+ * unless overridden with a `policy` lower in the hierarchy.
+ *
+ * A `constraint` defines an aspect of a resource's configuration that can be
+ * controlled by an organization's policy administrator. `Policies` are a
+ * collection of `constraints` that defines their allowable configuration on a
+ * particular resource and its child resources.
+ *
+ * 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.
+ *
+ * This class is currently experimental and may be subject to changes.
+ *
