+/**
+ * Service Description: Service for Auto-Completion.
+ *
+ * 
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:
+ *
+ * 
{@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * try (CompletionServiceClient completionServiceClient = CompletionServiceClient.create()) {
+ *   CompleteQueryRequest request =
+ *       CompleteQueryRequest.newBuilder()
+ *           .setDataStore(
+ *               DataStoreName.ofProjectLocationDataStoreName(
+ *                       "[PROJECT]", "[LOCATION]", "[DATA_STORE]")
+ *                   .toString())
+ *           .setQuery("query107944136")
+ *           .setQueryModel("queryModel-184930495")
+ *           .setUserPseudoId("userPseudoId-1155274652")
+ *           .setIncludeTailSuggestions(true)
+ *           .build();
+ *   CompleteQueryResponse response = completionServiceClient.completeQuery(request);
+ * }
+ * }

+ *
+ * 
Note: close() needs to be called on the CompletionServiceClient object to clean up resources
+ * such as threads. In the example above, try-with-resources is used, which automatically calls
+ * close().
+ *
+ * 
The surface of this class includes several types of Java methods for each of the API's
+ * methods:
+ *
+ * 
    
+ *   
  1. A "flattened" method. With this type of method, the fields of the request type have been
+ *       converted into function parameters. It may be the case that not all fields are available as
+ *       parameters, and not every API method will have a flattened method entry point.
+ *   
  2. A "request object" method. This type of method only takes one parameter, a request object,
+ *       which must be constructed before the call. Not every API method will have a request object
+ *       method.
+ *   
  3. A "callable" method. This type of method takes no parameters and returns an immutable API
+ *       callable object, which can be used to initiate calls to the service.
+ * 

+ *
+ * 
See the individual methods for example code.
+ *
+ * 
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 parse
+ * method to extract the individual identifiers contained within names that are returned.
+ *
+ * 
This class can be customized by passing in a custom instance of CompletionServiceSettings to
+ * create(). For example:
+ *
+ * 
To customize credentials:
+ *
+ * 
{@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * CompletionServiceSettings completionServiceSettings =
+ *     CompletionServiceSettings.newBuilder()
+ *         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
+ *         .build();
+ * CompletionServiceClient completionServiceClient =
+ *     CompletionServiceClient.create(completionServiceSettings);
+ * }

+ *
+ * 
To customize the endpoint:
+ *
+ * 
{@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * CompletionServiceSettings completionServiceSettings =
+ *     CompletionServiceSettings.newBuilder().setEndpoint(myEndpoint).build();
+ * CompletionServiceClient completionServiceClient =
+ *     CompletionServiceClient.create(completionServiceSettings);
+ * }

+ *
+ * 
To use REST (HTTP1.1/JSON) transport (instead of gRPC) for sending and receiving requests over
+ * the wire:
+ *
+ * 
{@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * CompletionServiceSettings completionServiceSettings =
+ *     CompletionServiceSettings.newHttpJsonBuilder().build();
+ * CompletionServiceClient completionServiceClient =
+ *     CompletionServiceClient.create(completionServiceSettings);
+ * }

+ *
+ *

+/**
+ * Settings class to configure an instance of {@link CompletionServiceClient}.
+ *
+ * 
The default instance has everything set to sensible defaults:
+ *
+ * 
    
+ *   
  • The default service address (discoveryengine.googleapis.com) and default port (443) are
+ *       used.
+ *   
  • Credentials are acquired automatically through Application Default Credentials.
+ *   
  • Retries are configured for idempotent methods but not for non-idempotent methods.
+ * 

+ *
+ * 
The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * 
For example, to set the total timeout of completeQuery to 30 seconds:
+ *
+ * 
{@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * CompletionServiceSettings.Builder completionServiceSettingsBuilder =

+ *             .setTotalTimeout(Duration.ofSeconds(30))

+/**
+ * Service Description: Service for conversational search.
+ *
+ * 
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:
+ *
+ * 
{@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * try (ConversationalSearchServiceClient conversationalSearchServiceClient =
+ *     ConversationalSearchServiceClient.create()) {
+ *   ConversationName name =
+ *       ConversationName.ofProjectLocationDataStoreConversationName(
+ *           "[PROJECT]", "[LOCATION]", "[DATA_STORE]", "[CONVERSATION]");
+ *   TextInput query = TextInput.newBuilder().build();
+ *   ConverseConversationResponse response =
+ *       conversationalSearchServiceClient.converseConversation(name, query);
+ * }
+ * }

+ *
+ * 
Note: close() needs to be called on the ConversationalSearchServiceClient object to clean up
+ * resources such as threads. In the example above, try-with-resources is used, which automatically
+ * calls close().
+ *
+ * 
The surface of this class includes several types of Java methods for each of the API's
+ * methods:
+ *
+ * 
    
+ *   
  1. A "flattened" method. With this type of method, the fields of the request type have been
+ *       converted into function parameters. It may be the case that not all fields are available as
+ *       parameters, and not every API method will have a flattened method entry point.
+ *   
  2. A "request object" method. This type of method only takes one parameter, a request object,
+ *       which must be constructed before the call. Not every API method will have a request object
+ *       method.
+ *   
  3. A "callable" method. This type of method takes no parameters and returns an immutable API
+ *       callable object, which can be used to initiate calls to the service.
+ * 

+ *
+ * 
See the individual methods for example code.
+ *
+ * 
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 parse
+ * method to extract the individual identifiers contained within names that are returned.
+ *
+ * 
This class can be customized by passing in a custom instance of
+ * ConversationalSearchServiceSettings to create(). For example:
+ *
+ * 
To customize credentials:
+ *
+ * 
{@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * ConversationalSearchServiceSettings conversationalSearchServiceSettings =
+ *     ConversationalSearchServiceSettings.newBuilder()
+ *         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
+ *         .build();
+ * ConversationalSearchServiceClient conversationalSearchServiceClient =
+ *     ConversationalSearchServiceClient.create(conversationalSearchServiceSettings);
+ * }

+ *
+ * 
To customize the endpoint:
+ *
+ * 
{@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * ConversationalSearchServiceSettings conversationalSearchServiceSettings =
+ *     ConversationalSearchServiceSettings.newBuilder().setEndpoint(myEndpoint).build();
+ * ConversationalSearchServiceClient conversationalSearchServiceClient =
+ *     ConversationalSearchServiceClient.create(conversationalSearchServiceSettings);
+ * }

+ *
+ * 
To use REST (HTTP1.1/JSON) transport (instead of gRPC) for sending and receiving requests over
+ * the wire:
+ *
+ * 
{@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * ConversationalSearchServiceSettings conversationalSearchServiceSettings =
+ *     ConversationalSearchServiceSettings.newHttpJsonBuilder().build();
+ * ConversationalSearchServiceClient conversationalSearchServiceClient =
+ *     ConversationalSearchServiceClient.create(conversationalSearchServiceSettings);
+ * }

+ *
+ *

+/**
+ * Settings class to configure an instance of {@link ConversationalSearchServiceClient}.
+ *
+ * 
The default instance has everything set to sensible defaults:
+ *
+ * 
    
+ *   
  • The default service address (discoveryengine.googleapis.com) and default port (443) are
+ *       used.
+ *   
  • Credentials are acquired automatically through Application Default Credentials.
+ *   
  • Retries are configured for idempotent methods but not for non-idempotent methods.
+ * 

+ *
+ * 
The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * 
For example, to set the total timeout of converseConversation to 30 seconds:
+ *
+ * 
{@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * ConversationalSearchServiceSettings.Builder conversationalSearchServiceSettingsBuilder =

+ *             .setTotalTimeout(Duration.ofSeconds(30))

+ *
+ * 
The surface of this class includes several types of Java methods for each of the API's
+ * methods:
+ *
+ * 
    
+ *   
  1. A "flattened" method. With this type of method, the fields of the request type have been
+ *       converted into function parameters. It may be the case that not all fields are available as
+ *       parameters, and not every API method will have a flattened method entry point.
+ *   
  2. A "request object" method. This type of method only takes one parameter, a request object,
+ *       which must be constructed before the call. Not every API method will have a request object
+ *       method.
+ *   
  3. A "callable" method. This type of method takes no parameters and returns an immutable API
+ *       callable object, which can be used to initiate calls to the service.
+ * 

+ *
+ * 
See the individual methods for example code.
+ *
+ * 
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 parse
+ * method to extract the individual identifiers contained within names that are returned.
+ *
+ * 
This class can be customized by passing in a custom instance of DocumentServiceSettings to
+ * create(). For example:
+ *
+ * 
To customize credentials:
+ *
+ * 
{@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * DocumentServiceSettings documentServiceSettings =
+ *     DocumentServiceSettings.newBuilder()
+ *         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
+ *         .build();
+ * DocumentServiceClient documentServiceClient =
+ *     DocumentServiceClient.create(documentServiceSettings);
+ * }

+ *
+ * 
To customize the endpoint:
+ *
+ * 
{@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * DocumentServiceSettings documentServiceSettings =
+ *     DocumentServiceSettings.newBuilder().setEndpoint(myEndpoint).build();
+ * DocumentServiceClient documentServiceClient =
+ *     DocumentServiceClient.create(documentServiceSettings);
+ * }

+ *
+ * 
To use REST (HTTP1.1/JSON) transport (instead of gRPC) for sending and receiving requests over
+ * the wire:
+ *
+ * 
{@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * DocumentServiceSettings documentServiceSettings =
+ *     DocumentServiceSettings.newHttpJsonBuilder().build();
+ * DocumentServiceClient documentServiceClient =
+ *     DocumentServiceClient.create(documentServiceSettings);
+ * }

+ *
+ *

+/**
+ * Settings class to configure an instance of {@link DocumentServiceClient}.
+ *
+ * 
The default instance has everything set to sensible defaults:
+ *
+ * 
    
+ *   
  • The default service address (discoveryengine.googleapis.com) and default port (443) are
+ *       used.
+ *   
  • Credentials are acquired automatically through Application Default Credentials.
+ *   
  • Retries are configured for idempotent methods but not for non-idempotent methods.
+ * 

+ *
+ * 
The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * 
For example, to set the total timeout of getDocument to 30 seconds:
+ *
+ * 
{@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * DocumentServiceSettings.Builder documentServiceSettingsBuilder =

+ *         documentServiceSettingsBuilder

+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setTotalTimeout(Duration.ofSeconds(30))
+ *             .build());

+ *           .setValidateOnly(true)
+ *           .putAllParams(new HashMap())
+ *           .putAllUserLabels(new HashMap())
+ *           .build();
+ *   RecommendResponse response = recommendationServiceClient.recommend(request);
+ * }
+ * }

+ *
+ * 
Note: close() needs to be called on the RecommendationServiceClient object to clean up
+ * resources such as threads. In the example above, try-with-resources is used, which automatically
+ * calls close().
+ *
+ * 
The surface of this class includes several types of Java methods for each of the API's
+ * methods:
+ *
+ * 
    
+ *   
  1. A "flattened" method. With this type of method, the fields of the request type have been
+ *       converted into function parameters. It may be the case that not all fields are available as
+ *       parameters, and not every API method will have a flattened method entry point.
+ *   
  2. A "request object" method. This type of method only takes one parameter, a request object,
+ *       which must be constructed before the call. Not every API method will have a request object
+ *       method.
+ *   
  3. A "callable" method. This type of method takes no parameters and returns an immutable API
+ *       callable object, which can be used to initiate calls to the service.
+ * 

+ *
+ * 
See the individual methods for example code.
+ *
+ * 
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 parse
+ * method to extract the individual identifiers contained within names that are returned.
+ *
+ * 
This class can be customized by passing in a custom instance of RecommendationServiceSettings
+ * to create(). For example:
+ *
+ * 
To customize credentials:
+ *
+ * 
{@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * RecommendationServiceSettings recommendationServiceSettings =
+ *     RecommendationServiceSettings.newBuilder()
+ *         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
+ *         .build();
+ * RecommendationServiceClient recommendationServiceClient =
+ *     RecommendationServiceClient.create(recommendationServiceSettings);
+ * }

+ *
+ * 
To customize the endpoint:
+ *
+ * 
{@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * RecommendationServiceSettings recommendationServiceSettings =
+ *     RecommendationServiceSettings.newBuilder().setEndpoint(myEndpoint).build();
+ * RecommendationServiceClient recommendationServiceClient =
+ *     RecommendationServiceClient.create(recommendationServiceSettings);
+ * }

+ *
+ * 
To use REST (HTTP1.1/JSON) transport (instead of gRPC) for sending and receiving requests over
+ * the wire:
+ *
+ * 
{@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * RecommendationServiceSettings recommendationServiceSettings =
+ *     RecommendationServiceSettings.newHttpJsonBuilder().build();
+ * RecommendationServiceClient recommendationServiceClient =
+ *     RecommendationServiceClient.create(recommendationServiceSettings);
+ * }

+ *
+ *

+/**
+ * Settings class to configure an instance of {@link RecommendationServiceClient}.
+ *
+ * 
The default instance has everything set to sensible defaults:
+ *
+ * 
    
+ *   
  • The default service address (discoveryengine.googleapis.com) and default port (443) are
+ *       used.
+ *   
  • Credentials are acquired automatically through Application Default Credentials.
+ *   
  • Retries are configured for idempotent methods but not for non-idempotent methods.
+ * 

+ *
+ * 
The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * 
For example, to set the total timeout of recommend to 30 seconds:
+ *
+ * 
{@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.

+/**
+ * Service Description: Service for managing [Schema][google.cloud.discoveryengine.v1alpha.Schema]s.
+ *
+ * 
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:
+ *
+ * 
{@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * try (SchemaServiceClient schemaServiceClient = SchemaServiceClient.create()) {
+ *   SchemaName name =
+ *       SchemaName.ofProjectLocationDataStoreSchemaName(
+ *           "[PROJECT]", "[LOCATION]", "[DATA_STORE]", "[SCHEMA]");
+ *   Schema response = schemaServiceClient.getSchema(name);
+ * }
+ * }

+ *
+ * 
Note: close() needs to be called on the SchemaServiceClient object to clean up resources such
+ * as threads. In the example above, try-with-resources is used, which automatically calls close().
+ *
+ * 
The surface of this class includes several types of Java methods for each of the API's
+ * methods:
+ *
+ * 
    
+ *   
  1. A "flattened" method. With this type of method, the fields of the request type have been
+ *       converted into function parameters. It may be the case that not all fields are available as
+ *       parameters, and not every API method will have a flattened method entry point.
+ *   
  2. A "request object" method. This type of method only takes one parameter, a request object,
+ *       which must be constructed before the call. Not every API method will have a request object
+ *       method.
+ *   
  3. A "callable" method. This type of method takes no parameters and returns an immutable API
+ *       callable object, which can be used to initiate calls to the service.
+ * 

+ *
+ * 
See the individual methods for example code.
+ *
+ * 
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 parse
+ * method to extract the individual identifiers contained within names that are returned.
+ *
+ * 
This class can be customized by passing in a custom instance of SchemaServiceSettings to
+ * create(). For example:
+ *
+ * 
To customize credentials:
+ *
+ * 
{@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * SchemaServiceSettings schemaServiceSettings =
+ *     SchemaServiceSettings.newBuilder()
+ *         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
+ *         .build();
+ * SchemaServiceClient schemaServiceClient = SchemaServiceClient.create(schemaServiceSettings);
+ * }

+ *
+ * 
To customize the endpoint:
+ *
+ * 
{@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * SchemaServiceSettings schemaServiceSettings =
+ *     SchemaServiceSettings.newBuilder().setEndpoint(myEndpoint).build();
+ * SchemaServiceClient schemaServiceClient = SchemaServiceClient.create(schemaServiceSettings);
+ * }

+ *
+ * 
To use REST (HTTP1.1/JSON) transport (instead of gRPC) for sending and receiving requests over
+ * the wire:
+ *
+ * 
{@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.

+/**
+ * Settings class to configure an instance of {@link SchemaServiceClient}.
+ *
+ * 
The default instance has everything set to sensible defaults:
+ *
+ * 
    
+ *   
  • The default service address (discoveryengine.googleapis.com) and default port (443) are
+ *       used.
+ *   
  • Credentials are acquired automatically through Application Default Credentials.
+ *   
  • Retries are configured for idempotent methods but not for non-idempotent methods.
+ * 

+ *
+ * 
The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * 
For example, to set the total timeout of getSchema to 30 seconds:
+ *
+ * 
{@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * SchemaServiceSettings.Builder schemaServiceSettingsBuilder = SchemaServiceSettings.newBuilder();
+ * schemaServiceSettingsBuilder
+ *     .getSchemaSettings()
+ *     .setRetrySettings(
+ *         schemaServiceSettingsBuilder
+ *             .getSchemaSettings()
+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setTotalTimeout(Duration.ofSeconds(30))
+ *             .build());
+ * SchemaServiceSettings schemaServiceSettings = schemaServiceSettingsBuilder.build();
+ * }

+/**
+ * Service Description: Service for search.
+ *
+ * 
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:
+ *
+ * 
{@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * try (SearchServiceClient searchServiceClient = SearchServiceClient.create()) {
+ *   SearchRequest request =
+ *       SearchRequest.newBuilder()
+ *           .setServingConfig(
+ *               ServingConfigName.ofProjectLocationDataStoreServingConfigName(
+ *                       "[PROJECT]", "[LOCATION]", "[DATA_STORE]", "[SERVING_CONFIG]")
+ *                   .toString())
+ *           .setBranch(
+ *               BranchName.ofProjectLocationDataStoreBranchName(
+ *                       "[PROJECT]", "[LOCATION]", "[DATA_STORE]", "[BRANCH]")
+ *                   .toString())
+ *           .setQuery("query107944136")
+ *           .setImageQuery(SearchRequest.ImageQuery.newBuilder().build())
+ *           .setPageSize(883849137)
+ *           .setPageToken("pageToken873572522")
+ *           .setOffset(-1019779949)
+ *           .setFilter("filter-1274492040")
+ *           .setOrderBy("orderBy-1207110587")
+ *           .setUserInfo(UserInfo.newBuilder().build())
+ *           .addAllFacetSpecs(new ArrayList())
+ *           .setBoostSpec(SearchRequest.BoostSpec.newBuilder().build())
+ *           .putAllParams(new HashMap())
+ *           .setQueryExpansionSpec(SearchRequest.QueryExpansionSpec.newBuilder().build())
+ *           .setSpellCorrectionSpec(SearchRequest.SpellCorrectionSpec.newBuilder().build())
+ *           .setUserPseudoId("userPseudoId-1155274652")
+ *           .setContentSearchSpec(SearchRequest.ContentSearchSpec.newBuilder().build())
+ *           .setEmbeddingSpec(SearchRequest.EmbeddingSpec.newBuilder().build())
+ *           .setRankingExpression("rankingExpression2110320494")
+ *           .setSafeSearch(true)
+ *           .putAllUserLabels(new HashMap())
+ *           .build();
+ *   for (SearchResponse.SearchResult element : searchServiceClient.search(request).iterateAll()) {
+ *     // doThingsWith(element);
+ *   }
+ * }
+ * }

+ *
+ * 
Note: close() needs to be called on the SearchServiceClient object to clean up resources such
+ * as threads. In the example above, try-with-resources is used, which automatically calls close().
+ *
+ * 
The surface of this class includes several types of Java methods for each of the API's
+ * methods:
+ *
+ * 
    
+ *   
  1. A "flattened" method. With this type of method, the fields of the request type have been
+ *       converted into function parameters. It may be the case that not all fields are available as
+ *       parameters, and not every API method will have a flattened method entry point.
+ *   
  2. A "request object" method. This type of method only takes one parameter, a request object,
+ *       which must be constructed before the call. Not every API method will have a request object
+ *       method.
+ *   
  3. A "callable" method. This type of method takes no parameters and returns an immutable API
+ *       callable object, which can be used to initiate calls to the service.
+ * 

+ *
+ * 
See the individual methods for example code.
+ *
+ * 
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 parse
+ * method to extract the individual identifiers contained within names that are returned.
+ *
+ * 
This class can be customized by passing in a custom instance of SearchServiceSettings to
+ * create(). For example:
+ *
+ * 
To customize credentials:
+ *
+ * 
{@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * SearchServiceSettings searchServiceSettings =
+ *     SearchServiceSettings.newBuilder()
+ *         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
+ *         .build();
+ * SearchServiceClient searchServiceClient = SearchServiceClient.create(searchServiceSettings);
+ * }

+ *
+ * 
To customize the endpoint:
+ *
+ * 
{@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * SearchServiceSettings searchServiceSettings =
+ *     SearchServiceSettings.newBuilder().setEndpoint(myEndpoint).build();
+ * SearchServiceClient searchServiceClient = SearchServiceClient.create(searchServiceSettings);
+ * }

+ *
+ * 
To use REST (HTTP1.1/JSON) transport (instead of gRPC) for sending and receiving requests over
+ * the wire:
+ *
+ * 
{@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * SearchServiceSettings searchServiceSettings =
+ *     SearchServiceSettings.newHttpJsonBuilder().build();
+ * SearchServiceClient searchServiceClient = SearchServiceClient.create(searchServiceSettings);
+ * }

+ *
+ *

+/**
+ * Settings class to configure an instance of {@link SearchServiceClient}.
+ *
+ * 
The default instance has everything set to sensible defaults:
+ *
+ * 
    
+ *   
  • The default service address (discoveryengine.googleapis.com) and default port (443) are
+ *       used.
+ *   
  • Credentials are acquired automatically through Application Default Credentials.
+ *   
  • Retries are configured for idempotent methods but not for non-idempotent methods.
+ * 

+ *
+ * 
The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * 
For example, to set the total timeout of search to 30 seconds:
+ *
+ * 
{@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * SearchServiceSettings.Builder searchServiceSettingsBuilder = SearchServiceSettings.newBuilder();
+ * searchServiceSettingsBuilder
+ *     .searchSettings()

+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setTotalTimeout(Duration.ofSeconds(30))
+ *             .build());

+/**
+ * Service Description: Service for managing site search related resources.
+ *
+ * 
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:
+ *
+ * 
{@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * try (SiteSearchEngineServiceClient siteSearchEngineServiceClient =
+ *     SiteSearchEngineServiceClient.create()) {
+ *   RecrawlUrisRequest request =
+ *       RecrawlUrisRequest.newBuilder()
+ *           .setSiteSearchEngine(
+ *               SiteSearchEngineName.ofProjectLocationDataStoreName(
+ *                       "[PROJECT]", "[LOCATION]", "[DATA_STORE]")
+ *                   .toString())
+ *           .addAllUris(new ArrayList())
+ *           .build();
+ *   RecrawlUrisResponse response = siteSearchEngineServiceClient.recrawlUrisAsync(request).get();
+ * }
+ * }

+ *
+ * 
Note: close() needs to be called on the SiteSearchEngineServiceClient object to clean up
+ * resources such as threads. In the example above, try-with-resources is used, which automatically
+ * calls close().
+ *
+ * 
The surface of this class includes several types of Java methods for each of the API's
+ * methods:
+ *
+ * 
    
+ *   
  1. A "flattened" method. With this type of method, the fields of the request type have been
+ *       converted into function parameters. It may be the case that not all fields are available as
+ *       parameters, and not every API method will have a flattened method entry point.
+ *   
  2. A "request object" method. This type of method only takes one parameter, a request object,
+ *       which must be constructed before the call. Not every API method will have a request object
+ *       method.
+ *   
  3. A "callable" method. This type of method takes no parameters and returns an immutable API
+ *       callable object, which can be used to initiate calls to the service.
+ * 

+ *
+ * 
See the individual methods for example code.
+ *
+ * 
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 parse
+ * method to extract the individual identifiers contained within names that are returned.
+ *
+ * 
This class can be customized by passing in a custom instance of
+ * SiteSearchEngineServiceSettings to create(). For example:
+ *
+ * 
To customize credentials:
+ *
+ * 
{@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * SiteSearchEngineServiceSettings siteSearchEngineServiceSettings =
+ *     SiteSearchEngineServiceSettings.newBuilder()
+ *         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
+ *         .build();
+ * SiteSearchEngineServiceClient siteSearchEngineServiceClient =
+ *     SiteSearchEngineServiceClient.create(siteSearchEngineServiceSettings);
+ * }

+ *
+ * 
To customize the endpoint:
+ *
+ * 
{@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * SiteSearchEngineServiceSettings siteSearchEngineServiceSettings =
+ *     SiteSearchEngineServiceSettings.newBuilder().setEndpoint(myEndpoint).build();
+ * SiteSearchEngineServiceClient siteSearchEngineServiceClient =
+ *     SiteSearchEngineServiceClient.create(siteSearchEngineServiceSettings);
+ * }

+ *
+ * 
To use REST (HTTP1.1/JSON) transport (instead of gRPC) for sending and receiving requests over
+ * the wire:
+ *
+ * 
{@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * SiteSearchEngineServiceSettings siteSearchEngineServiceSettings =
+ *     SiteSearchEngineServiceSettings.newHttpJsonBuilder().build();
+ * SiteSearchEngineServiceClient siteSearchEngineServiceClient =
+ *     SiteSearchEngineServiceClient.create(siteSearchEngineServiceSettings);
+ * }

+ *
+ *

+/**
+ * Settings class to configure an instance of {@link SiteSearchEngineServiceClient}.
+ *
+ * 
The default instance has everything set to sensible defaults:
+ *
+ * 
    
+ *   
  • The default service address (discoveryengine.googleapis.com) and default port (443) are
+ *       used.
+ *   
  • Credentials are acquired automatically through Application Default Credentials.
+ *   
  • Retries are configured for idempotent methods but not for non-idempotent methods.
+ * 

+ *
+ * 
The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * 
For example, to set the total timeout of recrawlUris to 30 seconds:
+ *
+ * 
{@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library

+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setTotalTimeout(Duration.ofSeconds(30))

+/**
+ * Service Description: Service for ingesting end user actions on a website to Discovery Engine API.
+ *
+ * 
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:
+ *
+ * 
{@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * try (UserEventServiceClient userEventServiceClient = UserEventServiceClient.create()) {
+ *   WriteUserEventRequest request =
+ *       WriteUserEventRequest.newBuilder()
+ *           .setParent(
+ *               DataStoreName.ofProjectLocationDataStoreName(
+ *                       "[PROJECT]", "[LOCATION]", "[DATA_STORE]")
+ *                   .toString())
+ *           .setUserEvent(UserEvent.newBuilder().build())
+ *           .build();
+ *   UserEvent response = userEventServiceClient.writeUserEvent(request);
+ * }
+ * }

+ *
+ * 
Note: close() needs to be called on the UserEventServiceClient object to clean up resources
+ * such as threads. In the example above, try-with-resources is used, which automatically calls
+ * close().
+ *
+ * 
The surface of this class includes several types of Java methods for each of the API's
+ * methods:
+ *
+ * 
    
+ *   
  1. A "flattened" method. With this type of method, the fields of the request type have been
+ *       converted into function parameters. It may be the case that not all fields are available as
+ *       parameters, and not every API method will have a flattened method entry point.
+ *   
  2. A "request object" method. This type of method only takes one parameter, a request object,
+ *       which must be constructed before the call. Not every API method will have a request object
+ *       method.
+ *   
  3. A "callable" method. This type of method takes no parameters and returns an immutable API
+ *       callable object, which can be used to initiate calls to the service.
+ * 

+ *
+ * 
See the individual methods for example code.
+ *
+ * 
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 parse
+ * method to extract the individual identifiers contained within names that are returned.
+ *
+ * 
This class can be customized by passing in a custom instance of UserEventServiceSettings to
+ * create(). For example:
+ *
+ * 
To customize credentials:
+ *
+ * 
{@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * UserEventServiceSettings userEventServiceSettings =
+ *     UserEventServiceSettings.newBuilder()
+ *         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
+ *         .build();
+ * UserEventServiceClient userEventServiceClient =
+ *     UserEventServiceClient.create(userEventServiceSettings);
+ * }

+ *
+ * 
To customize the endpoint:
+ *
+ * 
{@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * UserEventServiceSettings userEventServiceSettings =
+ *     UserEventServiceSettings.newBuilder().setEndpoint(myEndpoint).build();
+ * UserEventServiceClient userEventServiceClient =
+ *     UserEventServiceClient.create(userEventServiceSettings);
+ * }

+ *
+ * 
To use REST (HTTP1.1/JSON) transport (instead of gRPC) for sending and receiving requests over
+ * the wire:
+ *
+ * 
{@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * UserEventServiceSettings userEventServiceSettings =
+ *     UserEventServiceSettings.newHttpJsonBuilder().build();
+ * UserEventServiceClient userEventServiceClient =
+ *     UserEventServiceClient.create(userEventServiceSettings);
+ * }

+ *
+ *

+/**
+ * Settings class to configure an instance of {@link UserEventServiceClient}.
+ *
+ * 
The default instance has everything set to sensible defaults:
+ *
+ * 
    
+ *   
  • The default service address (discoveryengine.googleapis.com) and default port (443) are
+ *       used.
+ *   
  • Credentials are acquired automatically through Application Default Credentials.
+ *   
  • Retries are configured for idempotent methods but not for non-idempotent methods.
+ * 

+ *
+ * 
The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * 
For example, to set the total timeout of writeUserEvent to 30 seconds:
+ *
+ * 
{@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * UserEventServiceSettings.Builder userEventServiceSettingsBuilder =
+ *     UserEventServiceSettings.newBuilder();
+ * userEventServiceSettingsBuilder
+ *     .writeUserEventSettings()
+ *     .setRetrySettings(
+ *         userEventServiceSettingsBuilder
+ *             .writeUserEventSettings()
+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setTotalTimeout(Duration.ofSeconds(30))
+ *             .build());
+ * UserEventServiceSettings userEventServiceSettings = userEventServiceSettingsBuilder.build();
+ * }

+/**
+ * Settings class to configure an instance of {@link CompletionServiceStub}.
+ *
+ * 
The default instance has everything set to sensible defaults:
+ *
+ * 
    
+ *   
  • The default service address (discoveryengine.googleapis.com) and default port (443) are
+ *       used.
+ *   
  • Credentials are acquired automatically through Application Default Credentials.
+ *   
  • Retries are configured for idempotent methods but not for non-idempotent methods.
+ * 

+ *
+ * 
The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * 
For example, to set the total timeout of completeQuery to 30 seconds:
+ *
+ * 
{@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * CompletionServiceStubSettings.Builder completionServiceSettingsBuilder =
+ *     CompletionServiceStubSettings.newBuilder();
+ * completionServiceSettingsBuilder
+ *     .completeQuerySettings()

+ *         completionServiceSettingsBuilder

+// AUTO-GENERATED DOCUMENTATION AND CLASS.
+/**
+ * Settings class to configure an instance of {@link ConversationalSearchServiceStub}.
+ *
+ * 
The default instance has everything set to sensible defaults:
+ *
+ * 
    
+ *   
  • The default service address (discoveryengine.googleapis.com) and default port (443) are
+ *       used.
+ *   
  • Credentials are acquired automatically through Application Default Credentials.
+ *   
  • Retries are configured for idempotent methods but not for non-idempotent methods.
+ * 

+ *
+ * 
The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * 
For example, to set the total timeout of converseConversation to 30 seconds:
+ *
+ * 
{@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * ConversationalSearchServiceStubSettings.Builder conversationalSearchServiceSettingsBuilder =
+ *     ConversationalSearchServiceStubSettings.newBuilder();
+ * conversationalSearchServiceSettingsBuilder
+ *     .converseConversationSettings()
+ *     .setRetrySettings(
+ *         conversationalSearchServiceSettingsBuilder
+ *             .converseConversationSettings()
+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setTotalTimeout(Duration.ofSeconds(30))
+ *             .build());
+ * ConversationalSearchServiceStubSettings conversationalSearchServiceSettings =
+ *     conversationalSearchServiceSettingsBuilder.build();
+ * }

+// AUTO-GENERATED DOCUMENTATION AND CLASS.
+/**
+ * Settings class to configure an instance of {@link DocumentServiceStub}.
+ *
+ * 
The default instance has everything set to sensible defaults:
+ *
+ * 
    
+ *   
  • The default service address (discoveryengine.googleapis.com) and default port (443) are
+ *       used.
+ *   
  • Credentials are acquired automatically through Application Default Credentials.
+ *   
  • Retries are configured for idempotent methods but not for non-idempotent methods.
+ * 

+ *
+ * 
The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * 
For example, to set the total timeout of getDocument to 30 seconds:
+ *
+ * 
{@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * DocumentServiceStubSettings.Builder documentServiceSettingsBuilder =
+ *     DocumentServiceStubSettings.newBuilder();
+ * documentServiceSettingsBuilder
+ *     .getDocumentSettings()
+ *     .setRetrySettings(
+ *         documentServiceSettingsBuilder
+ *             .getDocumentSettings()
+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setTotalTimeout(Duration.ofSeconds(30))
+ *             .build());
+ * DocumentServiceStubSettings documentServiceSettings = documentServiceSettingsBuilder.build();
+ * }

+/**
+ * Settings class to configure an instance of {@link RecommendationServiceStub}.
+ *
+ * 
The default instance has everything set to sensible defaults:
+ *
+ * 
    
+ *   
  • The default service address (discoveryengine.googleapis.com) and default port (443) are
+ *       used.
+ *   
  • Credentials are acquired automatically through Application Default Credentials.
+ *   
  • Retries are configured for idempotent methods but not for non-idempotent methods.
+ * 

+ *
+ * 
The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * 
For example, to set the total timeout of recommend to 30 seconds:
+ *
+ * 
{@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * RecommendationServiceStubSettings.Builder recommendationServiceSettingsBuilder =
+ *     RecommendationServiceStubSettings.newBuilder();
+ * recommendationServiceSettingsBuilder
+ *     .recommendSettings()
+ *     .setRetrySettings(
+ *         recommendationServiceSettingsBuilder
+ *             .recommendSettings()
+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setTotalTimeout(Duration.ofSeconds(30))

+/**
+ * Settings class to configure an instance of {@link SchemaServiceStub}.
+ *
+ * 
The default instance has everything set to sensible defaults:
+ *
+ * 
    
+ *   
  • The default service address (discoveryengine.googleapis.com) and default port (443) are
+ *       used.
+ *   
  • Credentials are acquired automatically through Application Default Credentials.
+ *   
  • Retries are configured for idempotent methods but not for non-idempotent methods.
+ * 

+ *
+ * 
The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * 
For example, to set the total timeout of getSchema to 30 seconds:
+ *
+ * 
{@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * SchemaServiceStubSettings.Builder schemaServiceSettingsBuilder =
+ *     SchemaServiceStubSettings.newBuilder();

+ *         schemaServiceSettingsBuilder

+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setTotalTimeout(Duration.ofSeconds(30))

The default instance has everything set to sensible defaults:

  • The default service address (discoveryengine.googleapis.com) and default port (443) are

+ * Settings class to configure an instance of {@link UserEventServiceStub}.
+ *
+ * 
The default instance has everything set to sensible defaults:
+ *
+ * 
    
+ *   
  • The default service address (discoveryengine.googleapis.com) and default port (443) are
+ *       used.
+ *   
  • Credentials are acquired automatically through Application Default Credentials.
+ *   
  • Retries are configured for idempotent methods but not for non-idempotent methods.
+ * 

+ *
+ * 
The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * 
For example, to set the total timeout of writeUserEvent to 30 seconds:
+ *
+ * 
{@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * UserEventServiceStubSettings.Builder userEventServiceSettingsBuilder =
