public interface Controller
Each View
has an associated Controller
. Controllers receive requests to handle the commands associated with user actions. The controller's handleEvent
method gets called with the appropriate Command
specified. If the Controller
does not handle the requested command it delegates the Command
to a supervising Controller
. Controllers are also responsible for determining the availability of a specific command. The update
method is called to do just that.
