+// AUTO-GENERATED DOCUMENTATION AND CLASS.
+/**
+ * Settings class to configure an instance of {@link CollectionServiceClient}.
+ *
+ * <p>The default instance has everything set to sensible defaults:
+ *
+ * <ul>
+ *   <li>The default service address (discoveryengine.googleapis.com) and default port (443) are
+ *       used.
+ *   <li>Credentials are acquired automatically through Application Default Credentials.
+ *   <li>Retries are configured for idempotent methods but not for non-idempotent methods.
+ * </ul>
+ *
+ * <p>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.
+ *
+ * <p>For example, to set the
+ * [RetrySettings](https://cloud.google.com/java/docs/reference/gax/latest/com.google.api.gax.retrying.RetrySettings)
+ * of getIamPolicy:
+ *
+ * <pre>{@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();
+ * }</pre>
+ *
+ * Please refer to the [Client Side Retry
+ * Guide](https://docs.cloud.google.com/java/docs/client-retries) for additional support in setting
+ * retries.
+ *
+ * <p>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:
+ *
+ * <pre>{@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();
+ * }</pre>

+/**
+ * Service Description: Service for data connector management.
+ *
+ * <p>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:
+ *
+ * <pre>{@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 (DataConnectorServiceClient dataConnectorServiceClient =
+ *     DataConnectorServiceClient.create()) {
+ *   DataConnectorName name = DataConnectorName.of("[PROJECT]", "[LOCATION]", "[COLLECTION]");
+ *   DataConnector response = dataConnectorServiceClient.getDataConnector(name);
+ * }
+ * }</pre>
+ *
+ * <p>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().

+/**
+ * Settings class to configure an instance of {@link DataConnectorServiceClient}.
+ *
+ * <p>The default instance has everything set to sensible defaults:
+ *
+ * <ul>
+ *   <li>The default service address (discoveryengine.googleapis.com) and default port (443) are
+ *       used.
+ *   <li>Credentials are acquired automatically through Application Default Credentials.
+ *   <li>Retries are configured for idempotent methods but not for non-idempotent methods.
+ * </ul>
+ *
+ * <p>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.
+ *
+ * <p>For example, to set the
+ * [RetrySettings](https://cloud.google.com/java/docs/reference/gax/latest/com.google.api.gax.retrying.RetrySettings)
+ * of getDataConnector:
+ *
+ * <pre>{@code

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

+ *             .setInitialRetryDelayDuration(Duration.ofMillis(500))
+ *             .setRetryDelayMultiplier(1.5)
+ *             .setMaxRetryDelayDuration(Duration.ofMillis(5000))
+ *             .setTotalTimeoutDuration(Duration.ofHours(24))

+// AUTO-GENERATED DOCUMENTATION AND CLASS.
+/**
+ * Settings class to configure an instance of {@link LicenseConfigServiceClient}.
+ *
+ * <p>The default instance has everything set to sensible defaults:
+ *
+ * <ul>
+ *   <li>The default service address (discoveryengine.googleapis.com) and default port (443) are
+ *       used.
+ *   <li>Credentials are acquired automatically through Application Default Credentials.
+ *   <li>Retries are configured for idempotent methods but not for non-idempotent methods.
+ * </ul>
+ *
+ * <p>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.
+ *
+ * <p>For example, to set the
+ * [RetrySettings](https://cloud.google.com/java/docs/reference/gax/latest/com.google.api.gax.retrying.RetrySettings)
+ * of createLicenseConfig:
+ *
+ * <pre>{@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.

+ * // - 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.Builder licenseConfigServiceSettingsBuilder =

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

+ *
+ * <p>This class can be customized by passing in a custom instance of WidgetConfigServiceSettings to

+ *
+ * <p>To customize credentials:

+ * WidgetConfigServiceClient widgetConfigServiceClient =

+ * }</pre>
+ *
+ * <p>To customize the endpoint:
+ *
+ * <pre>{@code

+ * WidgetConfigServiceClient widgetConfigServiceClient =
+ *     WidgetConfigServiceClient.create(widgetConfigServiceSettings);
+ * }</pre>
+ *
+ * <p>To use REST (HTTP1.1/JSON) transport (instead of gRPC) for sending and receiving requests over

+// AUTO-GENERATED DOCUMENTATION AND CLASS.
+/**
+ * Settings class to configure an instance of {@link CollectionServiceStub}.
+ *
+ * <p>The default instance has everything set to sensible defaults:
+ *
+ * <ul>
+ *   <li>The default service address (discoveryengine.googleapis.com) and default port (443) are
+ *       used.
+ *   <li>Credentials are acquired automatically through Application Default Credentials.
+ *   <li>Retries are configured for idempotent methods but not for non-idempotent methods.
+ * </ul>
+ *
+ * <p>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.
+ *
+ * <p>For example, to set the
+ * [RetrySettings](https://cloud.google.com/java/docs/reference/gax/latest/com.google.api.gax.retrying.RetrySettings)
+ * of getIamPolicy:
+ *
+ * <pre>{@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();
+ * }</pre>
+ *
+ * Please refer to the [Client Side Retry
+ * Guide](https://docs.cloud.google.com/java/docs/client-retries) for additional support in setting
+ * retries.
+ *
+ * <p>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:
+ *
+ * <pre>{@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();
+ * }</pre>

+ * Settings class to configure an instance of {@link DataConnectorServiceStub}.
+ *
+ * <p>The default instance has everything set to sensible defaults:
+ *
+ * <ul>
+ *   <li>The default service address (discoveryengine.googleapis.com) and default port (443) are
+ *       used.
+ *   <li>Credentials are acquired automatically through Application Default Credentials.
+ *   <li>Retries are configured for idempotent methods but not for non-idempotent methods.
+ * </ul>
+ *
+ * <p>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.
+ *
+ * <p>For example, to set the
+ * [RetrySettings](https://cloud.google.com/java/docs/reference/gax/latest/com.google.api.gax.retrying.RetrySettings)
+ * of getDataConnector:
+ *
+ * <pre>{@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 =

+ *
+ * Please refer to the [Client Side Retry
+ * Guide](https://docs.cloud.google.com/java/docs/client-retries) for additional support in setting
+ * retries.
+ *
+ * <p>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:
+ *
+ * <pre>{@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:

+ *             .setInitialRetryDelayDuration(Duration.ofMillis(500))
+ *             .setRetryDelayMultiplier(1.5)
+ *             .setMaxRetryDelayDuration(Duration.ofMillis(5000))

+       * TPM subscription instead of to the overall customer-configurable-
+       * pricing relationship. This per-instance granularity is intentional:
+       * the underlying SubV3 storage is per-(project, model_version), so
+       * each model has its own activation, termination, and deferred-update
+       * clock; surfacing that on the response gives customers the granularity
+       * they need to manage per-model commitments independently. QPM /
+       * IndexingCore differ — their storage is one row per (project,
+       * location), so their lifecycle is represented only by the whole-
+       * relationship scalars on ConfigurableBillingStatus.
