Class ApplicationWrapper

java.lang.Object

javax.faces.application.Application

javax.faces.application.ApplicationWrapper

All Implemented Interfaces:

FacesWrapper<Application>

public abstract class ApplicationWrapper
extends Application
implements FacesWrapper<Application>

Provides a simple implementation of Application that can be subclassed by developers wishing to provide specialized behavior to an existing Application instance. The default implementation of all methods is to call through to the wrapped Application.

Usage: extend this class and override getWrapped() to return the instance we are wrapping.
