public class IView
extends View
implements IViewDelegate, IToolTipSource
IView is a View that dynamically delegates selected method calls (such as mouseDown(), drawView(), etc.) to its IViewDelegate object. Each method has its own bit flag (e.g., MOUSE_DOWN for mouseDown() method) to enable delegation. If the bit flag for a method is set (by setDelegateFlag()), whenever the method is called, the delegate object's delegate() method is called with the bit flag and the IView itself. Method parameters and return value are both instance variables of IView (parameters have '__' prefix, return values have '_' prefix) so IViewDelegate can examine method parameters and/or modify the return value during delegation.
