025 * Subclass of {@link ModelMap} that implements the {@link Model} interface.
026 * Java 5 specific like the {@code Model} interface itself.
027 *
028 * <p>This is an implementation class exposed to handler methods by Spring MVC, typically via
029 * a declaration of the {@link org.springframework.ui.Model} interface. There is no need to
030 * build it within user code; a plain {@link org.springframework.ui.ModelMap} or even a just
031 * a regular {@link Map} with String keys will be good enough to return a user model.
