Class AppContextDelegate

java.lang.Object

diva.gui.AppContextDelegate

All Implemented Interfaces:

AppContext, RootPaneContainer

Direct Known Subclasses:

DesktopContext

public class AppContextDelegate
extends Object
implements AppContext

This class provides basic support for an instance of AppContext which delegates its operation to one of the basic AppContexts (usually an AppContext or an ApplicationContext.) This is similar to an interface adapter, except the default implementation of each method is to call the identical method on the delegate context.
