- Direct Known Subclasses:
BindingAwareModelMap
Subclass of
ModelMap
that implements the Model
interface.
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.
