Detailed Description

The interface definition for a PureMVC Controller.

In PureMVC, an IController implementor follows the 'Command and Controller' strategy, and assumes these responsibilities:

• Remembering which ICommands are intended to handle which INotifications.
• Registering itself as an IObserver with the View for each INotification that it has an ICommand mapping for.
• Creating a new instance of the proper ICommand to handle a given INotification when notified by the View.
• Calling the ICommand's execute method, passing in the INotification.
