public abstract class StateManagerWrapper extends StateManager
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.
