Class StateManagerWrapper

java.lang.Object

jakarta.faces.application.StateManager

jakarta.faces.application.StateManagerWrapper

All Implemented Interfaces:

FacesWrapper<StateManager>

public abstract class StateManagerWrapper
extends StateManager
implements FacesWrapper<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 push the implementation being wrapped to the constructor and use getWrapped() to access the instance being wrapped.

Since:

1.2

Constructor Details

StateManagerWrapper

@Deprecated
public StateManagerWrapper()

Deprecated.

Use the other constructor taking the implementation being wrapped.

StateManagerWrapper

public StateManagerWrapper(StateManager wrapped)

If this state manager has been decorated, the implementation doing the decorating should push the implementation being wrapped to this constructor. The getWrapped() will then return the implementation being wrapped.

Parameters:

wrapped - The implementation being wrapped.
