javax.faces.application.ResourceHandler

javax.faces.application.ResourceHandlerWrapper

All Implemented Interfaces:

FacesWrapper<ResourceHandler>

public abstract class ResourceHandlerWrapper
extends ResourceHandler
implements FacesWrapper<ResourceHandler>

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

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

Since:

2.0
