+ * [access policy] [google.identity.accesscontextmanager.v1.AccessPolicy] is

+ *
+ * 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.

+/**
+ * Service Description: The Artifact Registry API service.
+ *
+ * Artifact Registry is an artifact management system for storing artifacts
+ * from different package management systems.
+ *
+ * The resources managed by this API are:
+ *
+ * * Repositories, which group packages and their data.
+ * * Packages, which group versions and their tags.
+ * * Versions, which are specific forms of a package.
+ * * Tags, which represent alternative names for versions.
+ * * Files, which contain content and are optionally associated with a Package
+ * or Version.
+ *
+ * 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.

+ * These upgrade settings control the level of parallelism and the level of

+ * maxSurge controls the number of additional nodes that can be added to the
+ * node pool temporarily for the time of the upgrade to increase the number of
+ * available nodes.
+ * (maxUnavailable + maxSurge) determines the level of parallelism (how many
+ * nodes are being upgraded at the same time).
+ * Note: upgrades inevitably introduce some disruption since workloads need to
+ * be moved from old nodes to new, upgraded ones. Even if maxUnavailable=0,
+ * this holds true. (Disruption stays within the limits of
+ * PodDisruptionBudget, if it is configured.)
+ * Consider a hypothetical node pool with 5 nodes having maxSurge=2,
+ * maxUnavailable=1. This means the upgrade process upgrades 3 nodes
+ * simultaneously. It creates 2 additional (upgraded) nodes, then it brings
+ * down 3 old (not yet upgraded) nodes at the same time. This ensures that
+ * there are always at least 4 nodes available.
+ * These upgrade settings configure the upgrade strategy for the node pool.
+ * Use strategy to switch between the strategies applied to the node pool.
+ * If the strategy is ROLLING, use max_surge and max_unavailable to control
+ * the level of parallelism and the level of disruption caused by upgrade.
+ * 1. maxSurge controls the number of additional nodes that can be added to
+ * the node pool temporarily for the time of the upgrade to increase the
+ * number of available nodes.
+ * 2. maxUnavailable controls the number of nodes that can be simultaneously
+ * unavailable.
+ * 3. (maxUnavailable + maxSurge) determines the level of parallelism (how
+ * many nodes are being upgraded at the same time).
+ * If the strategy is BLUE_GREEN, use blue_green_settings to configure the
+ * blue-green upgrade related settings.
+ * 1. standard_rollout_policy is the default policy. The policy is used to
+ * control the way blue pool gets drained. The draining is executed in the
+ * batch mode. The batch size could be specified as either percentage of the
+ * node pool size or the number of nodes. batch_soak_duration is the soak
+ * time after each batch gets drained.
+ * 2. node_pool_soak_duration is the soak time after all blue nodes are
+ * drained. After this period, the blue pool nodes will be deleted.

+/**
+ * Service Description: Retrieves analysis results of Cloud components such as Docker container
+ * images. The Container Analysis API is an implementation of the
+ * [Grafeas](https://grafeas.io) API.
+ *
+ * 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.

+/**
+ * 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.

+/**
+ * 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.
+ *

+/**
+ * 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.

+/**
+ * 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

+/**
+ * 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.

+/**
+ * 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.

+/**
+ * Service Description: Each RPC normalizes the partition IDs of the keys in its input entities,
+ * and always returns entities with keys with normalized partition IDs.
+ * This applies to all keys and entities, including those in values, except keys
+ * with both an empty path and an empty or unset partition ID. Normalization of
+ * input keys sets the project ID (if not already set) to the project ID from
+ * the request.
+ *
+ *
+ * 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:
+ *
+ * ```
+ * $datastoreClient = new DatastoreClient();
+ * try {
+ *     $projectId = 'project_id';
+ *     $keys = [];
+ *     $response = $datastoreClient->allocateIds($projectId, $keys);
+ * } finally {
+ *     $datastoreClient->close();

+/**
+ * Service Description: Google Cloud Datastore Admin API
+ *
+ * The Datastore Admin API provides several admin services for Cloud Datastore.
+ *
+ * Concepts: Project, namespace, kind, and entity as defined in the Google Cloud
+ * Datastore API.
+ *
+ * Operation: An Operation represents work being performed in the background.
+ *
+ * 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).
+ *
+ * Export/Import Service:
+ *
+ * - 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 Service:
+ *
+ * - 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 Service:
+ *
+ * - 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.

+ * Represents a variable or an argument possibly of a compound object type.
+ * Note how the following variables are represented:
+ * 1) A simple variable:
+ *     int x = 5
+ *     { name: "x", value: "5", type: "int" }  // Captured variable
+ * 2) A compound object:
+ *     struct T {
+ *         int m1;
+ *         int m2;
+ *     };
+ *     T x = { 3, 7 };
+ *     {  // Captured variable
+ *         name: "x",
+ *         type: "T",
+ *         members { name: "m1", value: "3", type: "int" },
+ *         members { name: "m2", value: "7", type: "int" }
+ *     }
+ * 3) A pointer where the pointee was captured:
+ *     T x = { 3, 7 };
+ *     T* p = &x;
+ *     {   // Captured variable
+ *         name: "p",
+ *         type: "T*",
+ *         value: "0x00500500",
+ *         members { name: "m1", value: "3", type: "int" },
+ *         members { name: "m2", value: "7", type: "int" }
+ *     }
+ * 4) A pointer where the pointee was not captured:
+ *     T* p = new T;
+ *     {   // Captured variable
+ *         name: "p",
+ *         type: "T*",
+ *         value: "0x00400400"
+ *         status { is_error: true, description { format: "unavailable" } }
+ *     }
+ * The status should describe the reason for the missing value,
+ * such as `<optimized out>`, `<inaccessible>`, `<pointers limit reached>`.
+ * Note that a null pointer should not have members.
+ * 5) An unnamed value:
+ *     int* p = new int(7);
+ *     {   // Captured variable
+ *         name: "p",
+ *         value: "0x00500500",
+ *         type: "int*",
+ *         members { value: "7", type: "int" } }
+ * 6) An unnamed pointer where the pointee was not captured:
+ *     int* p = new int(7);
+ *     int** pp = &p;
+ *     {  // Captured variable
+ *         name: "pp",
+ *         value: "0x00500500",
+ *         type: "int**",
+ *         members {
+ *             value: "0x00400400",
+ *             type: "int*"
+ *             status {
+ *                 is_error: true,
+ *                 description: { format: "unavailable" } }
+ *             }
+ *         }
+ *     }
+ * To optimize computation, memory and network traffic, variables that
+ * repeat in the output multiple times can be stored once in a shared
+ * variable table and be referenced using the `var_table_index` field.  The
+ * variables stored in the shared table are nameless and are essentially
+ * a partition of the complete variable. To reconstruct the complete
+ * variable, merge the referencing variable with the referenced variable.
+ * When using the shared variable table, the following variables:
+ *     T x = { 3, 7 };
+ *     T* p = &x;
+ *     T& r = x;
+ *     { name: "x", var_table_index: 3, type: "T" }  // Captured variables
+ *     { name: "p", value "0x00500500", type="T*", var_table_index: 3 }
+ *     { name: "r", type="T&", var_table_index: 3 }
+ *     {  // Shared variable table entry #3:
+ *         members { name: "m1", value: "3", type: "int" },
+ *         members { name: "m2", value: "7", type: "int" }
+ *     }
+ * Note that the pointer address is stored with the referencing variable
+ * and not with the referenced variable. This allows the referenced variable
+ * to be shared between pointers and references.
+ * The type field is optional. The debugger agent may or may not support it.

+/**
+ * Service Description: The Controller service provides the API for orchestrating a collection of
+ * debugger agents to perform debugging tasks. These agents are each attached
+ * to a process of an application which may include one or more replicas.
+ *
+ * The debugger agents register with the Controller to identify the application
+ * being debugged, the Debuggee. All agents that register with the same data,
+ * represent the same Debuggee, and are assigned the same `debuggee_id`.
+ *
+ * The debugger agents call the Controller to retrieve  the list of active
+ * Breakpoints. Agents with the same `debuggee_id` get the same breakpoints
+ * list. An agent that can fulfill the breakpoint request updates the
+ * Controller with the breakpoint result. The controller selects the first
+ * result received and discards the rest of the results.
+ * Agents that poll again for active breakpoints will no longer have
+ * the completed breakpoint in the list and should remove that breakpoint from
+ * their attached process.
+ *
+ * The Controller service does not provide a way to retrieve the results of
+ * a completed breakpoint. This functionality is available using the Debugger
+ * service.
+ *
+ * This class provides the ability to make remote calls to the backing service through method
+ * calls that map to API methods.

+ * Service Description: The Debugger service provides the API that allows users to collect run-time
+ * information from a running application, without stopping or slowing it down
+ * and without modifying its state.  An application may include one or
+ * more replicated processes performing the same work.
+ *
+ * A debugged application is represented using the Debuggee concept. The
+ * Debugger service provides a way to query for available debuggees, but does
+ * not provide a way to create one.  A debuggee is created using the Controller
+ * service, usually by running a debugger agent with the application.
+ *
+ * The Debugger service enables the client to set one or more Breakpoints on a
+ * Debuggee and collect the results of the set Breakpoints.
+ *
+ * This class provides the ability to make remote calls to the backing service through method
+ * calls that map to API methods.

+ * debugger agents to perform debugging tasks. These agents are each attached
+ * to a process of an application which may include one or more replicas.
+ *
+ * The debugger agents register with the Controller to identify the application
+ * being debugged, the Debuggee. All agents that register with the same data,
+ * represent the same Debuggee, and are assigned the same `debuggee_id`.
+ *
+ * The debugger agents call the Controller to retrieve  the list of active
+ * Breakpoints. Agents with the same `debuggee_id` get the same breakpoints
+ * list. An agent that can fulfill the breakpoint request updates the
+ * Controller with the breakpoint result. The controller selects the first
+ * result received and discards the rest of the results.
+ * Agents that poll again for active breakpoints will no longer have
+ * the completed breakpoint in the list and should remove that breakpoint from
+ * their attached process.
+ *
+ * The Controller service does not provide a way to retrieve the results of
+ * a completed breakpoint. This functionality is available using the Debugger
+ * service.
+ *
+ * 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:
+ *
+ * ```
+ * $controller2Client = new Controller2Client();
+ * try {
+ *     $debuggeeId = 'debuggee_id';
+ *     $response = $controller2Client->listActiveBreakpoints($debuggeeId);
+ * } finally {
+ *     $controller2Client->close();
+ * }
+ * ```
+ *
+ * @deprecated Please use the new service client {@see \Google\Cloud\Debugger\V2\Client\Controller2Client}.

+     *           For public website search only, supported values are:
+     *           * `user_country_code`: string. Default empty. If set to non-empty, results
+     *              are restricted or boosted based on the location provided.
+     *              For example, `user_country_code: "au"`

+     *           * `search_type`: double. Default empty. Enables non-webpage searching
+     *              depending on the value. The only valid non-default value is 1,
+     *              which enables image searching.
+     *              For example, `search_type: 1`
+     *     @type \Google\Cloud\DiscoveryEngine\V1\SearchRequest\QueryExpansionSpec $query_expansion_spec
+     *           The query expansion specification that specifies the conditions under which

+     *     @type string $user_pseudo_id
+     *           A unique identifier for tracking visitors. For example, this could be
+     *           implemented with an HTTP cookie, which should be able to uniquely identify
+     *           a visitor on a single device. This unique identifier should not change if
+     *           the visitor logs in or out of the website.
+     *           This field should NOT have a fixed value such as `unknown_visitor`.
+     *           This should be the same identifier as

+     *           and

+     *           The field must be a UTF-8 encoded string with a length limit of 128
+     *           characters. Otherwise, an  `INVALID_ARGUMENT`  error is returned.
+     *     @type \Google\Cloud\DiscoveryEngine\V1\SearchRequest\ContentSearchSpec $content_search_spec
+     *           A specification for configuring the behavior of content search.

+     *     @type array|\Google\Protobuf\Internal\MapField $user_labels
+     *           The user labels applied to a resource must meet the following requirements:
+     *           * Each resource can have multiple labels, up to a maximum of 64.
+     *           * Each label must be a key-value pair.
+     *           * Keys have a minimum length of 1 character and a maximum length of 63
+     *             characters and cannot be empty. Values can be empty and have a maximum
+     *             length of 63 characters.
+     *           * Keys and values can contain only lowercase letters, numeric characters,
+     *             underscores, and dashes. All characters must use UTF-8 encoding, and
+     *             international characters are allowed.
+     *           * The key portion of a label must be unique. However, you can use the same
+     *             key with multiple resources.
+     *           * Keys must start with a lowercase letter or international character.
+     *           See [Google Cloud
+     *           Document](https://cloud.google.com/resource-manager/docs/creating-managing-labels#requirements)
+     *           for more details.
+     *     @type \Google\Cloud\DiscoveryEngine\V1\SearchRequest\SearchAsYouTypeSpec $search_as_you_type_spec
+     *           Search as you type configuration. Only supported for the
+     *           [IndustryVertical.MEDIA][google.cloud.discoveryengine.v1.IndustryVertical.MEDIA]
+     *           vertical.
+     *     @type string $session
+     *           The session resource name. Optional.
+     *           Session allows users to do multi-turn /search API calls or coordination
+     *           between /search API calls and /answer API calls.
+     *           Example #1 (multi-turn /search API calls):
+     *             1. Call /search API with the auto-session mode (see below).
+     *             2. Call /search API with the session ID generated in the first call.
+     *                Here, the previous search query gets considered in query
+     *                standing. I.e., if the first query is "How did Alphabet do in 2022?"
+     *                and the current query is "How about 2023?", the current query will
+     *                be interpreted as "How did Alphabet do in 2023?".
+     *           Example #2 (coordination between /search API calls and /answer API calls):
+     *             1. Call /search API with the auto-session mode (see below).
+     *             2. Call /answer API with the session ID generated in the first call.
+     *                Here, the answer generation happens in the context of the search
+     *                results from the first search call.
+     *           Auto-session mode: when `projects/.../sessions/-` is used, a new session
+     *           gets automatically created. Otherwise, users can use the create-session API
+     *           to create a session manually.
+     *           Multi-turn Search feature is currently at private GA stage. Please use
+     *           v1alpha or v1beta version instead before we launch this feature to public
+     *           GA. Or ask for allowlisting through Google Support team.
+     *     @type \Google\Cloud\DiscoveryEngine\V1\SearchRequest\SessionSpec $session_spec
+     *           Session specification.

+     *           If you provide custom attributes for ingested user events, also include

+ *                                       * `view-item-list`: View of a panel or ordered list of Documents.

+ *                                       * `add-to-cart`: Add an item(s) to cart, e.g. in Retail online shopping

+ *
+ *                                       For example, this could be implemented with an HTTP cookie, which should be
+ *                                       able to uniquely identify a visitor on a single device. This unique
+ *                                       identifier should not change if the visitor log in/out of the website.
+ *
+ *                                       Do not set the field to the same fixed ID for different users. This mixes
+ *                                       the event history of those users together, which results in degraded model
+ *                                       quality.
+ *
+ *                                       The field must be a UTF-8 encoded string with a length limit of 128

+/**
+ * Service Description: Service for performing CRUD operations on Controls.
+ * Controls allow for custom logic to be implemented in the serving path.
+ * Controls need to be attached to a Serving Config to be considered during a
+ * request.
+ *
+ * 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.

+/**
+ * Message representing a set of files in a Cloud Storage bucket. Regular
+ * expressions are used to allow fine-grained control over which files in the
+ * bucket to include.
+ * Included files are those that match at least one item in `include_regex` and
+ * do not match any items in `exclude_regex`. Note that a file that matches
+ * items from both lists will _not_ be included. For a match to occur, the
+ * entire file path (i.e., everything in the url after the bucket name) must
+ * match the regular expression.
+ * For example, given the input `{bucket_name: "mybucket", include_regex:
+ * ["directory1/.*"], exclude_regex:
+ * ["directory1/excluded.*"]}`:
+ * * `gs://mybucket/directory1/myfile` will be included
+ * * `gs://mybucket/directory1/directory2/myfile` will be included (`.*` matches
+ * across `/`)
+ * * `gs://mybucket/directory0/directory1/myfile` will _not_ be included (the
+ * full path doesn't match any items in `include_regex`)
+ * * `gs://mybucket/directory1/excludedfile` will _not_ be included (the path
+ * matches an item in `exclude_regex`)
+ * If `include_regex` is left empty, it will match all files by default
+ * (this is equivalent to setting `include_regex: [".*"]`).
+ * Some other common use cases:
+ * * `{bucket_name: "mybucket", exclude_regex: [".*\.pdf"]}` will include all
+ * files in `mybucket` except for .pdf files
+ * * `{bucket_name: "mybucket", include_regex: ["directory/[^/]+"]}` will
+ * include all files directly under `gs://mybucket/directory/`, without matching
+ * across `/`

+ * This class provides the ability to make remote calls to the backing service through method

+ *
+ * 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.

+ * Service Description: Service to call Document AI to process documents according to the
+ * processor's definition. Processors are built using state-of-the-art Google
+ * AI such as natural language, computer vision, and translation to extract
+ * structured information from unstructured or semi-structured documents.
+ *
+ * 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.

+ * email from the registrar or by visiting the registrar's website.
+ *
+ * A few minutes after transfer approval, the resource transitions to state
+ * `ACTIVE`, indicating that the transfer was successful. If the transfer is
+ * rejected or the request expires without being approved, the resource can
+ * end up in state `TRANSFER_FAILED`. If transfer fails, you can safely delete
+ * the resource and retry the transfer.

+ * Service Description: EdgeNetwork API provides managed, highly available cloud dynamic network
+ * configuration service to the GEC customer to enable edge application and
+ * network function solutions. This allows the customers to easily define and
+ * configure the network setup and property to meet the workload requirement.
+ *
+ * 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.

+ * Service Description: An API for reporting error events.
+ *
+ * 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:
+ *
+ * ```
+ * $reportErrorsServiceClient = new ReportErrorsServiceClient();
+ * try {
+ *     $formattedProjectName = $reportErrorsServiceClient->projectName('[PROJECT]');
+ *     $event = new ReportedErrorEvent();
+ *     $response = $reportErrorsServiceClient->reportErrorEvent($formattedProjectName, $event);
+ * } finally {
+ *     $reportErrorsServiceClient->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.
+ *
+ * @experimental
+ *
+ * @deprecated Please use the new service client {@see \Google\Cloud\ErrorReporting\V1beta1\Client\ReportErrorsServiceClient}.

+     * Optional. The CEL expression used to modify how the destination-bound
+     * HTTP request is constructed.
+     * If a binding expression is not specified here, the message
+     * is treated as a CloudEvent and is mapped to the HTTP request according
+     * to the CloudEvent HTTP Protocol Binding Binary Content Mode. In this
+     * representation, all fields except the `data` and `datacontenttype`
+     * field on the message are mapped to HTTP request headers with a prefix
+     * of `ce-`.
+     * To construct the HTTP request payload and the value of the content-type
+     * HTTP header, the payload format is defined as follows:
+     * 1) Use the output_payload_format_type on the Pipeline.Destination if it
+     *    is set, else:
+     * 2) Use the input_payload_format_type on the Pipeline if it is set,
+     *    else:
+     * 3) Treat the payload as opaque binary data.
+     * The `data` field of the message is converted to the payload format or
+     * left as-is for case 3) and then attached as the payload of the HTTP
+     * request. The `content-type` header on the HTTP request is set to the
+     * payload format type or left empty for case 3). However, if a mediation
+     * has updated the `datacontenttype` field on the message so that it is
+     * not the same as the payload format type but it is still a prefix of the
+     * payload format type, then the `content-type` header on the HTTP request
+     * is set to this `datacontenttype` value. For example, if the
+     * `datacontenttype` is "application/json" and the payload format type is
+     * "application/json; charset=utf-8", then the `content-type` header on
+     * the HTTP request is set to "application/json; charset=utf-8".
+     * If a non-empty binding expression is specified then this expression is
+     * used to modify the default CloudEvent HTTP Protocol Binding Binary
+     * Content representation.
+     * The result of the CEL expression must be a map of key/value pairs
+     * which is used as follows:
+     * - If a map named `headers` exists on the result of the expression,
+     * then its key/value pairs are directly mapped to the HTTP request
+     * headers. The headers values are constructed from the corresponding
+     * value type’s canonical representation. If the `headers` field doesn’t
+     * exist then the resulting HTTP request will be the headers of the
+     * CloudEvent HTTP Binding Binary Content Mode representation of the final
+     * message. Note: If the specified binding expression, has updated the
+     * `datacontenttype` field on the message so that it is not the same as
+     * the payload format type but it is still a prefix of the payload format
+     * type, then the `content-type` header in the `headers` map is set to
+     * this `datacontenttype` value.
+     * - If a field named `body` exists on the result of the expression then
+     * its value is directly mapped to the body of the request. If the value
+     * of the `body` field is of type bytes or string then it is used for
+     * the HTTP request body as-is, with no conversion. If the body field is
+     * of any other type then it is converted to a JSON string. If the body
+     * field does not exist then the resulting payload of the HTTP request
+     * will be data value of the CloudEvent HTTP Binding Binary Content Mode
+     * representation of the final message as described earlier.
+     * - Any other fields in the resulting expression will be ignored.
+     * The CEL expression may access the incoming CloudEvent message in its
+     * definition, as follows:
+     * - The `data` field of the incoming CloudEvent message can be accessed
+     * using the `message.data` value. Subfields of `message.data` may also be
+     * accessed if an input_payload_format has been specified on the Pipeline.
+     * - Each attribute of the incoming CloudEvent message can be accessed
+     * using the `message.<key>` value, where <key> is replaced with the
+     * name of the attribute.
+     * - Existing headers can be accessed in the CEL expression using the
+     * `headers` variable. The `headers` variable defines a map of key/value
+     * pairs corresponding to the HTTP headers of the CloudEvent HTTP Binding
+     * Binary Content Mode representation of the final message as described
+     * earlier. For example, the following CEL expression can be used to
+     * construct an HTTP request by adding an additional header to the HTTP
+     * headers of the CloudEvent HTTP Binding Binary Content Mode
+     * representation of the final message and by overwriting the body of the
+     * request:
+     * ```
+     * {
+     *   "headers": headers.merge({"new-header-key": "new-header-value"}),
+     *   "body": "new-body"
+     * }
+     * ```
+     * Additionally, the following CEL extension functions are provided for
+     * use in this CEL expression:
+     * - toBase64Url:
+     *   map.toBase64Url() -> string
+     *     - Converts a CelValue to a base64url encoded string
+     * - toJsonString: map.toJsonString() -> string
+     *     - Converts a CelValue to a JSON string
+     * - merge:
+     *   map1.merge(map2) -> map3
+     *     - Merges the passed CEL map with the existing CEL map the
+     *     function is applied to.
+     *     - If the same key exists in both maps, if the key's value is type
+     *     map both maps are merged else the value from the passed map is
+     *     used.
+     * - denormalize:
+     *   map.denormalize() -> map
+     *     - Denormalizes a CEL map such that every value of type map or key
+     *     in the map is expanded to return a single level map.
+     *     - The resulting keys are "." separated indices of the map keys.
+     *     - For example:
+     *       {
+     *         "a": 1,
+     *         "b": {
+     *           "c": 2,
+     *           "d": 3
+     *         }
+     *         "e": [4, 5]
+     *       }
+     *       .denormalize()
+     *       -> {
+     *         "a": 1,
+     *         "b.c": 2,
+     *         "b.d": 3,
+     *         "e.0": 4,
+     *         "e.1": 5
+     *       }
+     * - setField:
+     *   map.setField(key, value) -> message
+     *     - Sets the field of the message with the given key to the
+     *     given value.
+     *     - If the field is not present it will be added.
+     *     - If the field is present it will be overwritten.
+     *     - The key can be a dot separated path to set a field in a nested
+     *     message.
+     *     - Key must be of type string.
+     *     - Value may be any valid type.
+     * - removeFields:
+     *   map.removeFields([key1, key2, ...]) -> message
+     *     - Removes the fields of the map with the given keys.
+     *     - The keys can be a dot separated path to remove a field in a
+     *     nested message.
+     *     - If a key is not found it will be ignored.
+     *     - Keys must be of type string.
+     * - toMap:
+     *   [map1, map2, ...].toMap() -> map
+     *     - Converts a CEL list of CEL maps to a single CEL map
+     * - toDestinationPayloadFormat():
+     *   message.data.toDestinationPayloadFormat() -> string or bytes
+     *     - Converts the message data to the destination payload format
+     *     specified in Pipeline.Destination.output_payload_format
+     *     - This function is meant to be applied to the message.data field.
+     *     - If the destination payload format is not set, the function will
+     *     return the message data unchanged.
+     * - toCloudEventJsonWithPayloadFormat:
+     *   message.toCloudEventJsonWithPayloadFormat() -> map
+     *     - Converts a message to the corresponding structure of JSON
+     *     format for CloudEvents
+     *     - This function applies toDestinationPayloadFormat() to the
+     *     message data. It also sets the corresponding datacontenttype of
+     *     the CloudEvent, as indicated by
+     *     Pipeline.Destination.output_payload_format. If no
+     *     output_payload_format is set it will use the existing
+     *     datacontenttype on the CloudEvent if present, else leave
+     *     datacontenttype absent.
+     *     - This function expects that the content of the message will
+     *     adhere to the standard CloudEvent format. If it doesn’t then this
+     *     function will fail.
+     *     - The result is a CEL map that corresponds to the JSON
+     *     representation of the CloudEvent. To convert that data to a JSON
+     *     string it can be chained with the toJsonString function.
+     * The Pipeline expects that the message it receives adheres to the
+     * standard CloudEvent format. If it doesn’t then the outgoing message
+     * request may fail with a persistent error.

+     * Optional. The CEL expression used to modify how the destination-bound
+     * HTTP request is constructed.
+     * If a binding expression is not specified here, the message
+     * is treated as a CloudEvent and is mapped to the HTTP request according
+     * to the CloudEvent HTTP Protocol Binding Binary Content Mode. In this
+     * representation, all fields except the `data` and `datacontenttype`
+     * field on the message are mapped to HTTP request headers with a prefix
+     * of `ce-`.
+     * To construct the HTTP request payload and the value of the content-type
+     * HTTP header, the payload format is defined as follows:
+     * 1) Use the output_payload_format_type on the Pipeline.Destination if it
+     *    is set, else:
+     * 2) Use the input_payload_format_type on the Pipeline if it is set,
+     *    else:
+     * 3) Treat the payload as opaque binary data.
+     * The `data` field of the message is converted to the payload format or
+     * left as-is for case 3) and then attached as the payload of the HTTP
+     * request. The `content-type` header on the HTTP request is set to the
+     * payload format type or left empty for case 3). However, if a mediation
+     * has updated the `datacontenttype` field on the message so that it is
+     * not the same as the payload format type but it is still a prefix of the
+     * payload format type, then the `content-type` header on the HTTP request
+     * is set to this `datacontenttype` value. For example, if the
+     * `datacontenttype` is "application/json" and the payload format type is
+     * "application/json; charset=utf-8", then the `content-type` header on
+     * the HTTP request is set to "application/json; charset=utf-8".
+     * If a non-empty binding expression is specified then this expression is
+     * used to modify the default CloudEvent HTTP Protocol Binding Binary
+     * Content representation.
+     * The result of the CEL expression must be a map of key/value pairs
+     * which is used as follows:
+     * - If a map named `headers` exists on the result of the expression,
+     * then its key/value pairs are directly mapped to the HTTP request
+     * headers. The headers values are constructed from the corresponding
+     * value type’s canonical representation. If the `headers` field doesn’t
+     * exist then the resulting HTTP request will be the headers of the
+     * CloudEvent HTTP Binding Binary Content Mode representation of the final
+     * message. Note: If the specified binding expression, has updated the
+     * `datacontenttype` field on the message so that it is not the same as
+     * the payload format type but it is still a prefix of the payload format
+     * type, then the `content-type` header in the `headers` map is set to
+     * this `datacontenttype` value.
+     * - If a field named `body` exists on the result of the expression then
+     * its value is directly mapped to the body of the request. If the value
+     * of the `body` field is of type bytes or string then it is used for
+     * the HTTP request body as-is, with no conversion. If the body field is
+     * of any other type then it is converted to a JSON string. If the body
+     * field does not exist then the resulting payload of the HTTP request
+     * will be data value of the CloudEvent HTTP Binding Binary Content Mode
+     * representation of the final message as described earlier.
+     * - Any other fields in the resulting expression will be ignored.
+     * The CEL expression may access the incoming CloudEvent message in its
+     * definition, as follows:
+     * - The `data` field of the incoming CloudEvent message can be accessed
+     * using the `message.data` value. Subfields of `message.data` may also be
+     * accessed if an input_payload_format has been specified on the Pipeline.
+     * - Each attribute of the incoming CloudEvent message can be accessed
+     * using the `message.<key>` value, where <key> is replaced with the
+     * name of the attribute.
+     * - Existing headers can be accessed in the CEL expression using the
+     * `headers` variable. The `headers` variable defines a map of key/value
+     * pairs corresponding to the HTTP headers of the CloudEvent HTTP Binding
+     * Binary Content Mode representation of the final message as described
+     * earlier. For example, the following CEL expression can be used to
+     * construct an HTTP request by adding an additional header to the HTTP
+     * headers of the CloudEvent HTTP Binding Binary Content Mode
+     * representation of the final message and by overwriting the body of the
+     * request:
+     * ```
+     * {
+     *   "headers": headers.merge({"new-header-key": "new-header-value"}),
+     *   "body": "new-body"
+     * }
+     * ```
+     * Additionally, the following CEL extension functions are provided for
+     * use in this CEL expression:
+     * - toBase64Url:
+     *   map.toBase64Url() -> string
+     *     - Converts a CelValue to a base64url encoded string
+     * - toJsonString: map.toJsonString() -> string
+     *     - Converts a CelValue to a JSON string
+     * - merge:
+     *   map1.merge(map2) -> map3
+     *     - Merges the passed CEL map with the existing CEL map the
+     *     function is applied to.
+     *     - If the same key exists in both maps, if the key's value is type
+     *     map both maps are merged else the value from the passed map is
+     *     used.
+     * - denormalize:
+     *   map.denormalize() -> map
+     *     - Denormalizes a CEL map such that every value of type map or key
+     *     in the map is expanded to return a single level map.
+     *     - The resulting keys are "." separated indices of the map keys.
+     *     - For example:
+     *       {
+     *         "a": 1,
+     *         "b": {

+     *     - Sets the field of the message with the given key to the

+ *
+ * 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.

+ * 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.
+ *
