javax.faces.application
Class ViewHandlerWrapper

java.lang.Object
  extended by javax.faces.application.ViewHandler
      extended by javax.faces.application.ViewHandlerWrapper
All Implemented Interfaces:
FacesWrapper<ViewHandler>

public abstract class ViewHandlerWrapper
extends ViewHandler
implements FacesWrapper<ViewHandler>

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

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

Since:
1.2
