+// AUTO-GENERATED DOCUMENTATION AND CLASS.
+/**
+ * Settings class to configure an instance of {@link PolicyBasedRoutingServiceClient}.
+ *
+ * <p>The default instance has everything set to sensible defaults:
+ *
+ * <ul>
+ *   <li>The default service address (networkconnectivity.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 total timeout of getPolicyBasedRoute to 30 seconds:
+ *
+ * <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
+ * PolicyBasedRoutingServiceSettings.Builder policyBasedRoutingServiceSettingsBuilder =
+ *     PolicyBasedRoutingServiceSettings.newBuilder();
+ * policyBasedRoutingServiceSettingsBuilder
+ *     .getPolicyBasedRouteSettings()
+ *     .setRetrySettings(
+ *         policyBasedRoutingServiceSettingsBuilder
+ *             .getPolicyBasedRouteSettings()
+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setTotalTimeout(Duration.ofSeconds(30))
+ *             .build());
+ * PolicyBasedRoutingServiceSettings policyBasedRoutingServiceSettings =
+ *     policyBasedRoutingServiceSettingsBuilder.build();
+ * }</pre>
