EE4J 10.0.0 · jakarta.faces.application.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 push the implementation being wrapped to the constructor and use getWrapped to access the instance being wrapped.
