-// AUTO-GENERATED DOCUMENTATION AND CLASS
-/**
- * Settings class to configure an instance of {@link LibraryClient}.
- *
- * <p>The default instance has everything set to sensible defaults:
- *
- * <ul>
- * <li>The default service address (library-example.googleapis.com) and default port (1234)
- * 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.
- *
- * For example, to set the total timeout of createShelf to 30 seconds:
- *
- * <pre>
- * <code>
- * LibrarySettings.Builder librarySettingsBuilder =
- *     LibrarySettings.newBuilder();
- * librarySettingsBuilder.createShelfSettings().getRetrySettings().toBuilder()
- *     .setTotalTimeout(Duration.ofSeconds(30));
- * LibrarySettings librarySettings = librarySettingsBuilder.build();
- * </code>
- * </pre>

+// AUTO-GENERATED DOCUMENTATION AND CLASS
+/**
+ * Settings class to configure an instance of {@link LibraryClient}.
+ *
+ * <p>The default instance has everything set to sensible defaults:
+ *
+ * <ul>
+ * <li>The default service address (library-example.googleapis.com) and default port (1234)
+ * 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.
+ *
+ * For example, to set the total timeout of createShelf to 30 seconds:
+ *
+ * <pre>
+ * <code>
+ * LibrarySettings.Builder librarySettingsBuilder =
+ *     LibrarySettings.newBuilder();
+ * librarySettingsBuilder.createShelfSettings().getRetrySettings().toBuilder()
+ *     .setTotalTimeout(Duration.ofSeconds(30));
+ * LibrarySettings librarySettings = librarySettingsBuilder.build();
+ * </code>
+ * </pre>

+// AUTO-GENERATED DOCUMENTATION AND SERVICE
+/**
+ * Service Description:
+ *
+ * <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>
+ * try (MyProtoClient myProtoClient = MyProtoClient.create()) {
+ *   MethodRequest request = MethodRequest.newBuilder().build();
+ *   MethodResponse response = myProtoClient.myMethod(request);
+ * }
+ * </code>
+ * </pre>
+ *
+ * <p>Note: close() needs to be called on the myProtoClient object to clean up resources such
+ * as threads. In the example above, try-with-resources is used, which automatically calls
+ * close().
+ *
+ * <p>The surface of this class includes several types of Java methods for each of the API's methods:
+ *
+ * <ol>
+ * <li> 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.
+ * <li> 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.
+ * <li> 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.
+ * </ol>
+ *
+ * <p>See the individual methods for example code.
+ *
+ * <p>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.
+ *
+ * <p>This class can be customized by passing in a custom instance of MyProtoSettings to
+ * create(). For example:
+ *
+ * To customize credentials:
+ *
+ * <pre>
+ * <code>
+ * MyProtoSettings myProtoSettings =
+ *     MyProtoSettings.newBuilder()
+ *         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
+ *         .build();
+ * MyProtoClient myProtoClient =
+ *     MyProtoClient.create(myProtoSettings);
+ * </code>
+ * </pre>
+ *
+ * To customize the endpoint:
+ *
+ * <pre>
+ * <code>
+ * MyProtoSettings myProtoSettings =
+ *     MyProtoSettings.newBuilder().setEndpoint(myEndpoint).build();
+ * MyProtoClient myProtoClient =
+ *     MyProtoClient.create(myProtoSettings);
+ * </code>
+ * </pre>

+ *
+ * Service Description: This API represents a simple digital library.  It lets you manage Shelf
+ * resources and Book resources in the library. It defines the following
+ * resource model:
+ *
+ * - The API has a collection of [Shelf][google.example.library.v1.Shelf]
+ *   resources, named ``bookShelves/&#42;``
+ *
+ * - Each Shelf has a collection of [Book][google.example.library.v1.Book]
+ *   resources, named `bookShelves/&#42;/books/&#42;`
+ *
+ * Check out [cloud docs!](/library/example/link).
+ * This is [not a cloud link](http://www.google.com).
+ *
+ * Service comment may include special characters: &lt;&gt;&amp;"`'{@literal @}.
+ *
+ * Also see this awesome doc there! and there! and everywhere!
+ *
+ * Sample for LibraryClient:
+ * <pre>
+ * <code>
+ * try (LibraryClient libraryClient = LibraryClient.create()) {
+ *   Shelf shelf = Shelf.newBuilder().build();
+ *   Shelf response = libraryClient.createShelf(shelf);
+ * }
+ * </code>

-// AUTO-GENERATED DOCUMENTATION AND SERVICE
+// AUTO-GENERATED DOCUMENTATION AND CLASS
 /**
- * Service Description:
- *
- * <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>
- * try (MyProtoClient myProtoClient = MyProtoClient.create()) {
- *   MethodRequest request = MethodRequest.newBuilder().build();
- *   MethodResponse response = myProtoClient.myMethod(request);
- * }
- * </code>
- * </pre>
- *
- * <p>Note: close() needs to be called on the myProtoClient object to clean up resources such
- * as threads. In the example above, try-with-resources is used, which automatically calls
- * close().
- *
- * <p>The surface of this class includes several types of Java methods for each of the API's methods:
- *
- * <ol>
- * <li> 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.
- * <li> 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.
- * <li> 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.
- * </ol>
- *
- * <p>See the individual methods for example code.
- *
- * <p>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.
- *
- * <p>This class can be customized by passing in a custom instance of MyProtoSettings to
- * create(). For example:
- *
- * To customize credentials:
- *
- * <pre>
- * <code>
- * MyProtoSettings myProtoSettings =
- *     MyProtoSettings.newBuilder()
- *         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
- *         .build();
- * MyProtoClient myProtoClient =
- *     MyProtoClient.create(myProtoSettings);
- * </code>
- * </pre>
- *
- * To customize the endpoint:
+ * gRPC callable factory implementation for Google Example Library API.
  *
- * <pre>
- * <code>
- * MyProtoSettings myProtoSettings =
- *     MyProtoSettings.newBuilder().setEndpoint(myEndpoint).build();
- * MyProtoClient myProtoClient =
- *     MyProtoClient.create(myProtoSettings);
- * </code>
- * </pre>
+ * <p>This class is for advanced usage.

- * Settings class to configure an instance of {@link MyProtoClient}.

- * <p>The default instance has everything set to sensible defaults:
- *
- * <ul>
- * <li>The default service address (library-example.googleapis.com) and default port (1234)

- * A client to Google Example Library API.
- *
- * The interfaces provided are listed below, along with usage samples.
- *
- * =============
- * LibraryClient
- * =============
- *
- * Service Description: This API represents a simple digital library.  It lets you manage Shelf
- * resources and Book resources in the library. It defines the following
- * resource model:
- *
- * - The API has a collection of [Shelf][google.example.library.v1.Shelf]
- *   resources, named ``bookShelves/&#42;``
- *
- * - Each Shelf has a collection of [Book][google.example.library.v1.Book]
- *   resources, named `bookShelves/&#42;/books/&#42;`
- *
- * Check out [cloud docs!](/library/example/link).
- * This is [not a cloud link](http://www.google.com).
- *
- * Service comment may include special characters: &lt;&gt;&amp;"`'{@literal @}.
- *
- * Also see this awesome doc there! and there! and everywhere!
- *
- * Sample for LibraryClient:
- * <pre>
- * <code>
- * try (LibraryClient libraryClient = LibraryClient.create()) {
- *   Shelf shelf = Shelf.newBuilder().build();
- *   Shelf response = libraryClient.createShelf(shelf);
- * }
- * </code>

- * =============
- *
- * Service Description:
- *
- * Sample for MyProtoClient:
- * <pre>
- * <code>
- * try (MyProtoClient myProtoClient = MyProtoClient.create()) {
- *   MethodRequest request = MethodRequest.newBuilder().build();
- *   MethodResponse response = myProtoClient.myMethod(request);

+ * Settings class to configure an instance of {@link LibraryServiceStub}.
+ *
+ * <p>The default instance has everything set to sensible defaults:
+ *
+ * <ul>
+ * <li>The default service address (library-example.googleapis.com) and default port (1234)
+ * 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.
+ *
+ * For example, to set the total timeout of createShelf to 30 seconds:
+ *
+ * <pre>
+ * <code>
+ * LibraryServiceStubSettings.Builder librarySettingsBuilder =
+ *     LibraryServiceStubSettings.newBuilder();
+ * librarySettingsBuilder.createShelfSettings().getRetrySettings().toBuilder()
+ *     .setTotalTimeout(Duration.ofSeconds(30));
+ * LibraryServiceStubSettings librarySettings = librarySettingsBuilder.build();

+ *
+ * <p>The default instance has everything set to sensible defaults:
+ *
+ * <ul>
+ * <li>The default service address (library-example.googleapis.com) and default port (1234)
+ * 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.
+ *
+ * For example, to set the total timeout of myMethod to 30 seconds:
+ *
+ * <pre>
+ * <code>
+ * MyProtoStubSettings.Builder myProtoSettingsBuilder =
+ *     MyProtoStubSettings.newBuilder();
+ * myProtoSettingsBuilder.myMethodSettings().getRetrySettings().toBuilder()
+ *     .setTotalTimeout(Duration.ofSeconds(30));
+ * MyProtoStubSettings myProtoSettings = myProtoSettingsBuilder.build();
+ * </code>
+ * </pre>

-// AUTO-GENERATED DOCUMENTATION AND CLASS
-/**
- * Settings class to configure an instance of {@link LibraryServiceStub}.
- *
- * <p>The default instance has everything set to sensible defaults:
- *
- * <ul>
- * <li>The default service address (library-example.googleapis.com) and default port (1234)
- * 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.
- *
- * For example, to set the total timeout of createShelf to 30 seconds:
- *
- * <pre>
- * <code>
- * LibraryServiceStubSettings.Builder librarySettingsBuilder =
- *     LibraryServiceStubSettings.newBuilder();
- * librarySettingsBuilder.createShelfSettings().getRetrySettings().toBuilder()
- *     .setTotalTimeout(Duration.ofSeconds(30));
- * LibraryServiceStubSettings librarySettings = librarySettingsBuilder.build();
- * </code>
- * </pre>

- * Settings class to configure an instance of {@link LibraryServiceStub}.
- *
- * <p>The default instance has everything set to sensible defaults:
- *
- * <ul>
- * <li>The default service address (library-example.googleapis.com) and default port (1234)
- * 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.
- *
- * For example, to set the total timeout of createShelf to 30 seconds:
- *
- * <pre>
- * <code>
- * LibraryServiceStubSettings.Builder librarySettingsBuilder =
- *     LibraryServiceStubSettings.newBuilder();
- * librarySettingsBuilder.createShelfSettings().getRetrySettings().toBuilder()
- *     .setTotalTimeout(Duration.ofSeconds(30));
- * LibraryServiceStubSettings librarySettings = librarySettingsBuilder.build();
- * </code>
- * </pre>

-// AUTO-GENERATED DOCUMENTATION AND CLASS
-/**
- * Settings class to configure an instance of {@link MyProtoStub}.
- *
- * <p>The default instance has everything set to sensible defaults:
- *
- * <ul>
- * <li>The default service address (library-example.googleapis.com) and default port (1234)
- * 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.
- *
- * For example, to set the total timeout of myMethod to 30 seconds:
- *
- * <pre>
- * <code>
- * MyProtoStubSettings.Builder myProtoSettingsBuilder =
- *     MyProtoStubSettings.newBuilder();
- * myProtoSettingsBuilder.myMethodSettings().getRetrySettings().toBuilder()
- *     .setTotalTimeout(Duration.ofSeconds(30));
- * MyProtoStubSettings myProtoSettings = myProtoSettingsBuilder.build();
- * </code>
- * </pre>

+// AUTO-GENERATED DOCUMENTATION AND CLASS
+/**
+ * Settings class to configure an instance of {@link LibraryServiceStub}.
+ *
+ * <p>The default instance has everything set to sensible defaults:
+ *
+ * <ul>
+ * <li>The default service address (library-example.googleapis.com) and default port (1234)
+ * 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.
+ *
+ * For example, to set the total timeout of createShelf to 30 seconds:
+ *
+ * <pre>
+ * <code>
+ * LibraryServiceStubSettings.Builder librarySettingsBuilder =
+ *     LibraryServiceStubSettings.newBuilder();
+ * librarySettingsBuilder.createShelfSettings().getRetrySettings().toBuilder()
+ *     .setTotalTimeout(Duration.ofSeconds(30));
+ * LibraryServiceStubSettings librarySettings = librarySettingsBuilder.build();
+ * </code>
+ * </pre>
