public abstract class ViewHandlerWrapper extends 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.
