public class ExtendedModelMap extends ModelMap implements Model
ModelMap
that implements the Model
interface.
Java 5 specific like the Model
interface itself.
This is an implementation class exposed to handler methods by Spring MVC, typically via
a declaration of the Model
interface. There is no need to
build it within user code; a plain ModelMap
or even a just
a regular Map
with String keys will be good enough to return a user model.

Collections
are not added to
the model when using this method because we cannot correctly determine
the true convention name. View code should check for null
rather
than for empty collections as is already done by JSTL tags.
