+ * Service Description: Service for managing Acl Configuration.
+ *
+ * 
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

+ *       UpdateAclConfigRequest.newBuilder().setAclConfig(AclConfig.newBuilder().build()).build();
+ *   AclConfig response = aclConfigServiceClient.updateAclConfig(request);
+ * }
+ * }

+ *
+ * 
Note: close() needs to be called on the AclConfigServiceClient object to clean up resources
+ * such as threads. In the example above, try-with-resources is used, which automatically calls
+ * close().
+ *
+ * 
+ *    
+ *    
+ *      
+ *      
+ *      
+ *    
+ *    
+ *      
+ *      
+ *

Methods
MethodDescriptionMethod Variants
 UpdateAclConfig
 Default ACL configuration for use in a location of a customer's project. Updates will only reflect to new data stores. Existing data stores will still use the old value.

+ *      
Request object method variants only take one parameter, a request object, which must be constructed before the call.

+ *      
    
+ *           
  •  updateAclConfig(UpdateAclConfigRequest request)
+ *      

+ *      
Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

+ *      
    
+ *           
  •  updateAclConfigCallable()
+ *      

+ *       
 GetAclConfig
 Gets the [AclConfig][google.cloud.discoveryengine.v1.AclConfig].

+ *      
Request object method variants only take one parameter, a request object, which must be constructed before the call.

+ *      
    
+ *           
  •  getAclConfig(GetAclConfigRequest request)
+ *      

+ *      
"Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method.

+ *      
    
+ *           
  •  getAclConfig(AclConfigName name)
+ *           
  •  getAclConfig(String name)
+ *      

+ *      
Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

+ *      
    
+ *           
  •  getAclConfigCallable()
+ *      

+ *       

+ *
+ * 
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 AclConfigServiceSettings 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
+ * AclConfigServiceSettings aclConfigServiceSettings =
+ *     AclConfigServiceSettings.newBuilder()
+ *         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
+ *         .build();
+ * AclConfigServiceClient aclConfigServiceClient =
+ *     AclConfigServiceClient.create(aclConfigServiceSettings);
+ * }

+ *
+ * 
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
+ * AclConfigServiceSettings aclConfigServiceSettings =
+ *     AclConfigServiceSettings.newBuilder().setEndpoint(myEndpoint).build();
+ * AclConfigServiceClient aclConfigServiceClient =
+ *     AclConfigServiceClient.create(aclConfigServiceSettings);
+ * }

+ *
+ * 
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
+ * AclConfigServiceSettings aclConfigServiceSettings =
+ *     AclConfigServiceSettings.newHttpJsonBuilder().build();
+ * AclConfigServiceClient aclConfigServiceClient =
+ *     AclConfigServiceClient.create(aclConfigServiceSettings);
+ * }

+ *
+ *

+/**
+ * Settings class to configure an instance of {@link AclConfigServiceClient}.
+ *
+ * 
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
+ * [RetrySettings](https://cloud.google.com/java/docs/reference/gax/latest/com.google.api.gax.retrying.RetrySettings)
+ * of updateAclConfig:
+ *
+ * 
{@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
+ * AclConfigServiceSettings.Builder aclConfigServiceSettingsBuilder =
+ *     AclConfigServiceSettings.newBuilder();

+ *     .updateAclConfigSettings()
+ *     .setRetrySettings(
+ *         aclConfigServiceSettingsBuilder
+ *             .updateAclConfigSettings()
+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setInitialRetryDelayDuration(Duration.ofSeconds(1))
+ *             .setInitialRpcTimeoutDuration(Duration.ofSeconds(5))
+ *             .setMaxAttempts(5)
+ *             .setMaxRetryDelayDuration(Duration.ofSeconds(30))
+ *             .setMaxRpcTimeoutDuration(Duration.ofSeconds(60))
+ *             .setRetryDelayMultiplier(1.3)
+ *             .setRpcTimeoutMultiplier(1.5)

+// AUTO-GENERATED DOCUMENTATION AND CLASS.
+/**
+ * Service Description: Service for managing
+ * [Collection][google.cloud.discoveryengine.v1.Collection]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 (CollectionServiceClient collectionServiceClient = CollectionServiceClient.create()) {
+ *   ResourceName resource = CollectionName.of("[PROJECT]", "[LOCATION]", "[COLLECTION]");
+ *   Policy response = collectionServiceClient.getIamPolicy(resource);
+ * }
+ * }

+ *
+ * 
Note: close() needs to be called on the CollectionServiceClient object to clean up resources
+ * such as threads. In the example above, try-with-resources is used, which automatically calls
+ * close().
+ *
+ * 
+ *    
+ *    
+ *      
+ *      
+ *      
+ *    
+ *    
+ *      
+ *      
+ *      
+ *    
+ *    
+ *      
+ *      
+ *

Methods
MethodDescriptionMethod Variants
 DeleteCollection
 Deletes a [Collection][google.cloud.discoveryengine.v1.Collection].

+ *      
Request object method variants only take one parameter, a request object, which must be constructed before the call.

+ *      
    
+ *           
  •  deleteCollectionAsync(DeleteCollectionRequest request)
+ *      

+ *      
Methods that return long-running operations have "Async" method variants that return `OperationFuture`, which is used to track polling of the service.

+ *      
    
+ *           
  •  deleteCollectionAsync(CollectionName name)
+ *           
  •  deleteCollectionAsync(String name)
+ *      

+ *      
Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

+ *      
    
+ *           
  •  deleteCollectionOperationCallable()
+ *           
  •  deleteCollectionCallable()
+ *      

+ *       
 GetIamPolicy
 Gets the IAM access control policy for a [Collection][google.cloud.discoveryengine.v1.Collection]. A `NOT_FOUND` error is returned if the resource does not exist. An empty policy is returned if the resource exists but does not have a policy set on it.

+ *      
Request object method variants only take one parameter, a request object, which must be constructed before the call.

+ *      
    
+ *           
  •  getIamPolicy(GetIamPolicyRequest request)
+ *      

+ *      
"Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method.

+ *      
    
+ *           
  •  getIamPolicy(ResourceName resource)
+ *           
  •  getIamPolicy(String resource)
+ *      

+ *      
Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

+ *      
    
+ *           
  •  getIamPolicyCallable()
+ *      

+ *       
 SetIamPolicy
 Sets the IAM access control policy for a [Collection][google.cloud.discoveryengine.v1.Collection]. A `NOT_FOUND` error is returned if the resource does not exist.
+ * 
  **Important:** When setting a policy directly on a Collection resource, the only recommended roles in the bindings are: `roles/discoveryengine.admin` `roles/discoveryengine.agentspaceAdmin` `roles/discoveryengine.viewer` `roles/discoveryengine.agentspaceViewer` `roles/discoveryengine.user` `roles/discoveryengine.agentspaceUser` Attempting to grant any other role will result in a warning in logging.

+ *      
Request object method variants only take one parameter, a request object, which must be constructed before the call.

+ *      
    
+ *           
  •  setIamPolicy(SetIamPolicyRequest request)
+ *      

+ *      
"Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method.

+ *      
    
+ *           
  •  setIamPolicy(ResourceName resource, Policy policy)
+ *           
  •  setIamPolicy(String resource, Policy policy)
+ *      

+ *      
Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

+ *      
    
+ *           
  •  setIamPolicyCallable()
+ *      

+ *       

+ *
+ * 
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 CollectionServiceSettings 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
+ * CollectionServiceSettings collectionServiceSettings =
+ *     CollectionServiceSettings.newBuilder()
+ *         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
+ *         .build();
+ * CollectionServiceClient collectionServiceClient =
+ *     CollectionServiceClient.create(collectionServiceSettings);
+ * }

+ *
+ * 
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
+ * CollectionServiceSettings collectionServiceSettings =
+ *     CollectionServiceSettings.newBuilder().setEndpoint(myEndpoint).build();
+ * CollectionServiceClient collectionServiceClient =
+ *     CollectionServiceClient.create(collectionServiceSettings);
+ * }

+ *
+ * 
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
+ * CollectionServiceSettings collectionServiceSettings =
+ *     CollectionServiceSettings.newHttpJsonBuilder().build();
+ * CollectionServiceClient collectionServiceClient =
+ *     CollectionServiceClient.create(collectionServiceSettings);
+ * }

+ *
+ *

+// AUTO-GENERATED DOCUMENTATION AND CLASS.
+/**
+ * Settings class to configure an instance of {@link CollectionServiceClient}.
+ *
+ * 
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
+ * [RetrySettings](https://cloud.google.com/java/docs/reference/gax/latest/com.google.api.gax.retrying.RetrySettings)
+ * of getIamPolicy:
+ *
+ * 
{@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
+ * CollectionServiceSettings.Builder collectionServiceSettingsBuilder =
+ *     CollectionServiceSettings.newBuilder();
+ * collectionServiceSettingsBuilder
+ *     .getIamPolicySettings()
+ *     .setRetrySettings(
+ *         collectionServiceSettingsBuilder
+ *             .getIamPolicySettings()
+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setInitialRetryDelayDuration(Duration.ofSeconds(1))
+ *             .setInitialRpcTimeoutDuration(Duration.ofSeconds(5))
+ *             .setMaxAttempts(5)
+ *             .setMaxRetryDelayDuration(Duration.ofSeconds(30))
+ *             .setMaxRpcTimeoutDuration(Duration.ofSeconds(60))
+ *             .setRetryDelayMultiplier(1.3)
+ *             .setRpcTimeoutMultiplier(1.5)
+ *             .setTotalTimeoutDuration(Duration.ofSeconds(300))
+ *             .build());
+ * CollectionServiceSettings collectionServiceSettings = collectionServiceSettingsBuilder.build();
+ * }

+ *
+ * Please refer to the [Client Side Retry
+ * Guide](https://docs.cloud.google.com/java/docs/client-retries) for additional support in setting
+ * retries.
+ *
+ * 
To configure the RetrySettings of a Long Running Operation method, create an
+ * OperationTimedPollAlgorithm object and update the RPC's polling algorithm. For example, to
+ * configure the RetrySettings for deleteCollection:
+ *
+ * 
{@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
+ * CollectionServiceSettings.Builder collectionServiceSettingsBuilder =
+ *     CollectionServiceSettings.newBuilder();
+ * TimedRetryAlgorithm timedRetryAlgorithm =
+ *     OperationalTimedPollAlgorithm.create(
+ *         RetrySettings.newBuilder()
+ *             .setInitialRetryDelayDuration(Duration.ofMillis(500))
+ *             .setRetryDelayMultiplier(1.5)
+ *             .setMaxRetryDelayDuration(Duration.ofMillis(5000))
+ *             .setTotalTimeoutDuration(Duration.ofHours(24))
+ *             .build());
+ * collectionServiceSettingsBuilder
+ *     .createClusterOperationSettings()
+ *     .setPollingAlgorithm(timedRetryAlgorithm)
+ *     .build();
+ * }

+ * Service Description: Service for data connector management.
+ *
+ * 
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:

+ * }
+ * }

+ *
+ * 
Note: close() needs to be called on the DataConnectorServiceClient object to clean up
+ * resources such as threads. In the example above, try-with-resources is used, which automatically
+ * calls close().

Methods
MethodDescriptionMethod Variants
 SetUpDataConnector
 Creates a [Collection][google.cloud.discoveryengine.v1.Collection] and sets up the [DataConnector][google.cloud.discoveryengine.v1.DataConnector] for it. To stop a [DataConnector][google.cloud.discoveryengine.v1.DataConnector] after setup, use the [CollectionService.DeleteCollection][google.cloud.discoveryengine.v1.CollectionService.DeleteCollection] method.

+ *      
Request object method variants only take one parameter, a request object, which must be constructed before the call.

+ *      
    
+ *           
  •  setUpDataConnectorAsync(SetUpDataConnectorRequest request)
+ *      

+ *      
Methods that return long-running operations have "Async" method variants that return `OperationFuture`, which is used to track polling of the service.

+ *      
    
+ *           
  •  setUpDataConnectorAsync(LocationName parent, String collectionId, String collectionDisplayName, DataConnector dataConnector)
+ *           
  •  setUpDataConnectorAsync(String parent, String collectionId, String collectionDisplayName, DataConnector dataConnector)
+ *      

+ *      
Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

+ *      
    
+ *           
  •  setUpDataConnectorOperationCallable()
+ *           
  •  setUpDataConnectorCallable()
+ *      

+ *       
 GetDataConnector
 Gets the [DataConnector][google.cloud.discoveryengine.v1.DataConnector]. [DataConnector][google.cloud.discoveryengine.v1.DataConnector] is a singleton resource for each [Collection][google.cloud.discoveryengine.v1.Collection].

+ *      
Request object method variants only take one parameter, a request object, which must be constructed before the call.

+ *      
    
+ *           
  •  getDataConnector(GetDataConnectorRequest request)
+ *      

+ *      
"Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method.

+ *      
    
+ *           
  •  getDataConnector(DataConnectorName name)
+ *           
  •  getDataConnector(String name)
+ *      

+ *      
Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

+ *      
    
+ *           
  •  getDataConnectorCallable()
+ *      

+ *       
 UpdateDataConnector
 Updates a [DataConnector][google.cloud.discoveryengine.v1.DataConnector].

+ *      
Request object method variants only take one parameter, a request object, which must be constructed before the call.

+ *      
    
+ *           
  •  updateDataConnector(UpdateDataConnectorRequest request)
+ *      

+ *      
"Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method.

+ *      
    
+ *           
  •  updateDataConnector(DataConnector dataConnector, FieldMask updateMask)
+ *      

+ *      
Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

+ *      
    
+ *           
  •  updateDataConnectorCallable()
+ *      

+ *       

+ *
+ * 
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 DataConnectorServiceSettings
+ * 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
+ * DataConnectorServiceSettings dataConnectorServiceSettings =
+ *     DataConnectorServiceSettings.newBuilder()
+ *         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
+ *         .build();
+ * DataConnectorServiceClient dataConnectorServiceClient =
+ *     DataConnectorServiceClient.create(dataConnectorServiceSettings);
+ * }

+ *
+ * 
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
+ * DataConnectorServiceSettings dataConnectorServiceSettings =
+ *     DataConnectorServiceSettings.newBuilder().setEndpoint(myEndpoint).build();
+ * DataConnectorServiceClient dataConnectorServiceClient =
+ *     DataConnectorServiceClient.create(dataConnectorServiceSettings);
+ * }

+ *
+ * 
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
+ * DataConnectorServiceSettings dataConnectorServiceSettings =
+ *     DataConnectorServiceSettings.newHttpJsonBuilder().build();
+ * DataConnectorServiceClient dataConnectorServiceClient =
+ *     DataConnectorServiceClient.create(dataConnectorServiceSettings);
+ * }

+ *
+ *

+/**
+ * Settings class to configure an instance of {@link DataConnectorServiceClient}.
+ *
+ * 
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
+ * [RetrySettings](https://cloud.google.com/java/docs/reference/gax/latest/com.google.api.gax.retrying.RetrySettings)
+ * of getDataConnector:
+ *
+ * 
{@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
+ * DataConnectorServiceSettings.Builder dataConnectorServiceSettingsBuilder =
+ *     DataConnectorServiceSettings.newBuilder();
+ * dataConnectorServiceSettingsBuilder
+ *     .getDataConnectorSettings()
+ *     .setRetrySettings(
+ *         dataConnectorServiceSettingsBuilder
+ *             .getDataConnectorSettings()
+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setInitialRetryDelayDuration(Duration.ofSeconds(1))
+ *             .setInitialRpcTimeoutDuration(Duration.ofSeconds(5))
+ *             .setMaxAttempts(5)
+ *             .setMaxRetryDelayDuration(Duration.ofSeconds(30))
+ *             .setMaxRpcTimeoutDuration(Duration.ofSeconds(60))
+ *             .setRetryDelayMultiplier(1.3)
+ *             .setRpcTimeoutMultiplier(1.5)
+ *             .setTotalTimeoutDuration(Duration.ofSeconds(300))
+ *             .build());
+ * DataConnectorServiceSettings dataConnectorServiceSettings =
+ *     dataConnectorServiceSettingsBuilder.build();
+ * }

+ *
+ * Please refer to the [Client Side Retry
+ * Guide](https://docs.cloud.google.com/java/docs/client-retries) for additional support in setting
+ * retries.
+ *
+ * 
To configure the RetrySettings of a Long Running Operation method, create an
+ * OperationTimedPollAlgorithm object and update the RPC's polling algorithm. For example, to
+ * configure the RetrySettings for setUpDataConnector:
+ *
+ * 
{@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
+ * DataConnectorServiceSettings.Builder dataConnectorServiceSettingsBuilder =
+ *     DataConnectorServiceSettings.newBuilder();
+ * TimedRetryAlgorithm timedRetryAlgorithm =
+ *     OperationalTimedPollAlgorithm.create(
+ *         RetrySettings.newBuilder()
+ *             .setInitialRetryDelayDuration(Duration.ofMillis(500))
+ *             .setRetryDelayMultiplier(1.5)
+ *             .setMaxRetryDelayDuration(Duration.ofMillis(5000))
+ *             .setTotalTimeoutDuration(Duration.ofHours(24))
+ *             .build());
+ * dataConnectorServiceSettingsBuilder
+ *     .createClusterOperationSettings()
+ *     .setPollingAlgorithm(timedRetryAlgorithm)
+ *     .build();
+ * }

       CreateLicenseConfig
       Creates a [LicenseConfig][google.cloud.discoveryengine.v1.LicenseConfig] This method should only be used for creating NotebookLm licenses or Gemini Enterprise free trial licenses.
      		
+ *      
      Request object method variants only take one parameter, a request object, which must be constructed before the call.

      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 LicenseConfigServiceSettings
+ * 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
+ * LicenseConfigServiceSettings licenseConfigServiceSettings =
+ *     LicenseConfigServiceSettings.newBuilder()
+ *         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
+ *         .build();
+ * LicenseConfigServiceClient licenseConfigServiceClient =
+ *     LicenseConfigServiceClient.create(licenseConfigServiceSettings);
+ * }
      
+ *
+ * 
      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

+ * LicenseConfigServiceClient licenseConfigServiceClient =
+ *     LicenseConfigServiceClient.create(licenseConfigServiceSettings);
+ * }
      
+ *
+ * 
      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.

+// AUTO-GENERATED DOCUMENTATION AND CLASS.
+/**
+ * Settings class to configure an instance of {@link LicenseConfigServiceClient}.
+ *
+ * 
      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
+ * [RetrySettings](https://cloud.google.com/java/docs/reference/gax/latest/com.google.api.gax.retrying.RetrySettings)
+ * of createLicenseConfig:
+ *
+ * 
      {@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

+ *         licenseConfigServiceSettingsBuilder
+ *             .createLicenseConfigSettings()
+ *             .getRetrySettings()

+ *             .setMaxAttempts(5)
+ *             .setMaxRetryDelayDuration(Duration.ofSeconds(30))
+ *             .setMaxRpcTimeoutDuration(Duration.ofSeconds(60))
+ *             .setRetryDelayMultiplier(1.3)
+ *             .setRpcTimeoutMultiplier(1.5)

+ *             .build());
+ * LicenseConfigServiceSettings licenseConfigServiceSettings =
+ *     licenseConfigServiceSettingsBuilder.build();
+ * }
      
+ *
+ * Please refer to the [Client Side Retry
+ * Guide](https://docs.cloud.google.com/java/docs/client-retries) for additional support in setting
+ * retries.

+/**
+ * Service Description: Service for managing User Stores.
+ *
+ * 
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 (UserStoreServiceClient userStoreServiceClient = UserStoreServiceClient.create()) {
+ *   UserStoreName name = UserStoreName.of("[PROJECT]", "[LOCATION]", "[USER_STORE]");
+ *   UserStore response = userStoreServiceClient.getUserStore(name);
+ * }
+ * }

+ *
+ * 
Note: close() needs to be called on the UserStoreServiceClient object to clean up resources
+ * such as threads. In the example above, try-with-resources is used, which automatically calls
+ * close().
+ *
+ * 
+ *    
+ *    
+ *      
+ *      
+ *      
+ *    
+ *    
+ *      
+ *      
+ *      
+ *    
+ *    
+ *      
+ *      
+ *      
+ *

Methods
MethodDescriptionMethod Variants
 GetUserStore
 Gets the User Store.

+ *      
Request object method variants only take one parameter, a request object, which must be constructed before the call.

+ *      
    
+ *           
  •  getUserStore(GetUserStoreRequest request)
+ *      

+ *      
"Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method.

+ *      
    
+ *           
  •  getUserStore(UserStoreName name)
+ *           
  •  getUserStore(String name)
+ *      

+ *      
Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

+ *      
    
+ *           
  •  getUserStoreCallable()
+ *      

+ *       
 UpdateUserStore
 Updates the User Store.

+ *      
Request object method variants only take one parameter, a request object, which must be constructed before the call.

+ *      
    
+ *           
  •  updateUserStore(UpdateUserStoreRequest request)
+ *      

+ *      
"Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method.

+ *      
    
+ *           
  •  updateUserStore(UserStore userStore, FieldMask updateMask)
+ *      

+ *      
Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

+ *      
    
+ *           
  •  updateUserStoreCallable()
+ *      

+ *       

+ *
+ * 
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 UserStoreServiceSettings 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
+ * UserStoreServiceSettings userStoreServiceSettings =
+ *     UserStoreServiceSettings.newBuilder()
+ *         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
+ *         .build();
+ * UserStoreServiceClient userStoreServiceClient =
+ *     UserStoreServiceClient.create(userStoreServiceSettings);
+ * }

+ *
+ * 
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
+ * UserStoreServiceSettings userStoreServiceSettings =
+ *     UserStoreServiceSettings.newBuilder().setEndpoint(myEndpoint).build();
+ * UserStoreServiceClient userStoreServiceClient =
+ *     UserStoreServiceClient.create(userStoreServiceSettings);
+ * }

+ *
+ * 
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
+ * UserStoreServiceSettings userStoreServiceSettings =
+ *     UserStoreServiceSettings.newHttpJsonBuilder().build();
+ * UserStoreServiceClient userStoreServiceClient =
+ *     UserStoreServiceClient.create(userStoreServiceSettings);
+ * }

+ *
+ * 
Please refer to the GitHub repository's samples for more quickstart code snippets.

+/**
+ * Settings class to configure an instance of {@link UserStoreServiceClient}.
+ *
+ * 
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
+ * [RetrySettings](https://cloud.google.com/java/docs/reference/gax/latest/com.google.api.gax.retrying.RetrySettings)
+ * of getUserStore:
+ *
+ * 
{@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
+ * UserStoreServiceSettings.Builder userStoreServiceSettingsBuilder =
+ *     UserStoreServiceSettings.newBuilder();
+ * userStoreServiceSettingsBuilder
+ *     .getUserStoreSettings()
+ *     .setRetrySettings(
+ *         userStoreServiceSettingsBuilder
+ *             .getUserStoreSettings()
+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setInitialRetryDelayDuration(Duration.ofSeconds(1))
+ *             .setInitialRpcTimeoutDuration(Duration.ofSeconds(5))
+ *             .setMaxAttempts(5)
+ *             .setMaxRetryDelayDuration(Duration.ofSeconds(30))
+ *             .setMaxRpcTimeoutDuration(Duration.ofSeconds(60))
+ *             .setRetryDelayMultiplier(1.3)
+ *             .setRpcTimeoutMultiplier(1.5)
+ *             .setTotalTimeoutDuration(Duration.ofSeconds(300))
+ *             .build());
+ * UserStoreServiceSettings userStoreServiceSettings = userStoreServiceSettingsBuilder.build();
+ * }

+ * retries.

+ * Service Description: Service for managing

+ *
+ * 
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.

+ *           "[PROJECT]", "[LOCATION]", "[DATA_STORE]", "[WIDGET_CONFIG]");
+ *   WidgetConfig response = widgetConfigServiceClient.getWidgetConfig(name);
+ * }
+ * }

+ *
+ * 
Note: close() needs to be called on the WidgetConfigServiceClient object to clean up resources
+ * such as threads. In the example above, try-with-resources is used, which automatically calls
+ * close().
+ *
+ * 
+ *    
+ *    
+ *

Methods
MethodDescriptionMethod Variants
 GetWidgetConfig
 Gets a [WidgetConfig][google.cloud.discoveryengine.v1.WidgetConfig].

+ *      
Request object method variants only take one parameter, a request object, which must be constructed before the call.

+ *      
    
+ *           
  •  getWidgetConfig(GetWidgetConfigRequest request)
+ *      

+ *      
"Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method.

+ *      
    
+ *           
  •  getWidgetConfig(WidgetConfigName name)
+ *           
  •  getWidgetConfig(String name)
+ *      

+ *      
Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

+ *      
    
+ *           
  •  getWidgetConfigCallable()
+ *      

+ *       
 UpdateWidgetConfig
 Update a WidgetConfig.

+ *      
Request object method variants only take one parameter, a request object, which must be constructed before the call.

+ *      
    
+ *           
  •  updateWidgetConfig(UpdateWidgetConfigRequest request)
+ *      

+ *      
"Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method.

+ *      
    
+ *           
  •  updateWidgetConfig(WidgetConfig widgetConfig, FieldMask updateMask)
+ *      

+ *      
Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

+ *      
    
+ *           
  •  updateWidgetConfigCallable()
+ *      

+ *       

+ *
+ * 
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 WidgetConfigServiceSettings 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
+ * WidgetConfigServiceSettings widgetConfigServiceSettings =
+ *     WidgetConfigServiceSettings.newBuilder()
+ *         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
+ *         .build();
+ * WidgetConfigServiceClient widgetConfigServiceClient =
+ *     WidgetConfigServiceClient.create(widgetConfigServiceSettings);
+ * }

+ *
+ * 
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
+ * WidgetConfigServiceSettings widgetConfigServiceSettings =
+ *     WidgetConfigServiceSettings.newBuilder().setEndpoint(myEndpoint).build();
+ * WidgetConfigServiceClient widgetConfigServiceClient =
+ *     WidgetConfigServiceClient.create(widgetConfigServiceSettings);
+ * }

+ *
+ * 
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
+ * WidgetConfigServiceSettings widgetConfigServiceSettings =
+ *     WidgetConfigServiceSettings.newHttpJsonBuilder().build();
+ * WidgetConfigServiceClient widgetConfigServiceClient =
+ *     WidgetConfigServiceClient.create(widgetConfigServiceSettings);
+ * }

+ *
+ *

+/**
+ * Settings class to configure an instance of {@link WidgetConfigServiceClient}.
+ *
+ * 
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
+ * [RetrySettings](https://cloud.google.com/java/docs/reference/gax/latest/com.google.api.gax.retrying.RetrySettings)
+ * of getWidgetConfig:
+ *
+ * 
{@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

+ *             .setInitialRpcTimeoutDuration(Duration.ofSeconds(5))
+ *             .setMaxAttempts(5)
+ *             .setMaxRetryDelayDuration(Duration.ofSeconds(30))
+ *             .setMaxRpcTimeoutDuration(Duration.ofSeconds(60))
+ *             .setRetryDelayMultiplier(1.3)
+ *             .setRpcTimeoutMultiplier(1.5)

+ *     widgetConfigServiceSettingsBuilder.build();
+ * }

+ * Please refer to the [Client Side Retry
+ * Guide](https://docs.cloud.google.com/java/docs/client-retries) for additional support in setting
+ * retries.

+/**
+ * Settings class to configure an instance of {@link CollectionServiceStub}.
+ *
+ * 
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
+ * [RetrySettings](https://cloud.google.com/java/docs/reference/gax/latest/com.google.api.gax.retrying.RetrySettings)
+ * of getIamPolicy:
+ *
+ * 
{@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
+ * CollectionServiceStubSettings.Builder collectionServiceSettingsBuilder =
+ *     CollectionServiceStubSettings.newBuilder();
+ * collectionServiceSettingsBuilder
+ *     .getIamPolicySettings()
+ *     .setRetrySettings(
+ *         collectionServiceSettingsBuilder
+ *             .getIamPolicySettings()
+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setInitialRetryDelayDuration(Duration.ofSeconds(1))
+ *             .setInitialRpcTimeoutDuration(Duration.ofSeconds(5))
+ *             .setMaxAttempts(5)
+ *             .setMaxRetryDelayDuration(Duration.ofSeconds(30))
+ *             .setMaxRpcTimeoutDuration(Duration.ofSeconds(60))
+ *             .setRetryDelayMultiplier(1.3)
+ *             .setRpcTimeoutMultiplier(1.5)
+ *             .setTotalTimeoutDuration(Duration.ofSeconds(300))
+ *             .build());
+ * CollectionServiceStubSettings collectionServiceSettings =
+ *     collectionServiceSettingsBuilder.build();
+ * }

+ *
+ * Please refer to the [Client Side Retry
+ * Guide](https://docs.cloud.google.com/java/docs/client-retries) for additional support in setting
+ * retries.
+ *
+ * 
To configure the RetrySettings of a Long Running Operation method, create an
+ * OperationTimedPollAlgorithm object and update the RPC's polling algorithm. For example, to
+ * configure the RetrySettings for deleteCollection:
+ *
+ * 
{@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
+ * CollectionServiceStubSettings.Builder collectionServiceSettingsBuilder =
+ *     CollectionServiceStubSettings.newBuilder();
+ * TimedRetryAlgorithm timedRetryAlgorithm =
+ *     OperationalTimedPollAlgorithm.create(
+ *         RetrySettings.newBuilder()
+ *             .setInitialRetryDelayDuration(Duration.ofMillis(500))
+ *             .setRetryDelayMultiplier(1.5)
+ *             .setMaxRetryDelayDuration(Duration.ofMillis(5000))
+ *             .setTotalTimeoutDuration(Duration.ofHours(24))
+ *             .build());
+ * collectionServiceSettingsBuilder
+ *     .createClusterOperationSettings()
+ *     .setPollingAlgorithm(timedRetryAlgorithm)
+ *     .build();
+ * }

+/**
+ * Settings class to configure an instance of {@link DataConnectorServiceStub}.
+ *
+ * 
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
+ * [RetrySettings](https://cloud.google.com/java/docs/reference/gax/latest/com.google.api.gax.retrying.RetrySettings)
+ * of getDataConnector:
+ *
+ * 
{@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
+ * DataConnectorServiceStubSettings.Builder dataConnectorServiceSettingsBuilder =
+ *     DataConnectorServiceStubSettings.newBuilder();
+ * dataConnectorServiceSettingsBuilder
+ *     .getDataConnectorSettings()
+ *     .setRetrySettings(
+ *         dataConnectorServiceSettingsBuilder
+ *             .getDataConnectorSettings()
+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setInitialRetryDelayDuration(Duration.ofSeconds(1))
+ *             .setInitialRpcTimeoutDuration(Duration.ofSeconds(5))
+ *             .setMaxAttempts(5)
+ *             .setMaxRetryDelayDuration(Duration.ofSeconds(30))
+ *             .setMaxRpcTimeoutDuration(Duration.ofSeconds(60))
+ *             .setRetryDelayMultiplier(1.3)
+ *             .setRpcTimeoutMultiplier(1.5)
+ *             .setTotalTimeoutDuration(Duration.ofSeconds(300))
+ *             .build());
+ * DataConnectorServiceStubSettings dataConnectorServiceSettings =
+ *     dataConnectorServiceSettingsBuilder.build();
+ * }

+ *
+ * Please refer to the [Client Side Retry
+ * Guide](https://docs.cloud.google.com/java/docs/client-retries) for additional support in setting
+ * retries.
+ *
+ * 
To configure the RetrySettings of a Long Running Operation method, create an
+ * OperationTimedPollAlgorithm object and update the RPC's polling algorithm. For example, to
+ * configure the RetrySettings for setUpDataConnector:
+ *
+ * 
{@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
+ * DataConnectorServiceStubSettings.Builder dataConnectorServiceSettingsBuilder =
+ *     DataConnectorServiceStubSettings.newBuilder();
+ * TimedRetryAlgorithm timedRetryAlgorithm =
+ *     OperationalTimedPollAlgorithm.create(
+ *         RetrySettings.newBuilder()
+ *             .setInitialRetryDelayDuration(Duration.ofMillis(500))
+ *             .setRetryDelayMultiplier(1.5)
+ *             .setMaxRetryDelayDuration(Duration.ofMillis(5000))
+ *             .setTotalTimeoutDuration(Duration.ofHours(24))
+ *             .build());
+ * dataConnectorServiceSettingsBuilder
+ *     .createClusterOperationSettings()
+ *     .setPollingAlgorithm(timedRetryAlgorithm)
+ *     .build();
+ * }

+/**
+ * Settings class to configure an instance of {@link LicenseConfigServiceStub}.
+ *
+ * 
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
+ * [RetrySettings](https://cloud.google.com/java/docs/reference/gax/latest/com.google.api.gax.retrying.RetrySettings)
+ * of createLicenseConfig:
+ *
+ * 
{@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

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

+ * Settings class to configure an instance of {@link UserStoreServiceStub}.
+ *
+ * 
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.
+ *
+ *

+ * [RetrySettings](https://cloud.google.com/java/docs/reference/gax/latest/com.google.api.gax.retrying.RetrySettings)

+/**
+ * Settings class to configure an instance of {@link WidgetConfigServiceStub}.
+ *
+ * 
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
+ * [RetrySettings](https://cloud.google.com/java/docs/reference/gax/latest/com.google.api.gax.retrying.RetrySettings)
+ * of getWidgetConfig:
+ *
+ * 
{@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
