javax.faces.application.StateManagerWrapper
public abstract class StateManagerWrapper
Provides a simple implementation of StateManager that can
be subclassed by developers wishing to provide specialized behavior
to an existing StateManager instance. The default
implementation of all methods is to call through to the wrapped
StateManager.
Usage: extend this class and override getWrapped() to
return the instance we are wrapping.
