public abstract class ExceptionHandlerWrapper extends ExceptionHandler implements FacesWrapper<ExceptionHandler>
Provides a simple implementation of ExceptionHandler
that can
be subclassed by developers wishing to provide specialized behavior
to an existing ExceptionHandler
instance. The default
implementation of all methods is to call through to the wrapped
ExceptionHandler
instance.
Usage: extend this class and override getWrapped()
to
return the instance we are wrapping.
