NavigationCaseWrapper (Java(TM) EE 8 Specification APIs)

java.lang.Object
- javax.faces.application.NavigationCase
- - javax.faces.application.NavigationCaseWrapper

All Implemented Interfaces:

FacesWrapper<NavigationCase>
```
public abstract class NavigationCaseWrapper
extends NavigationCase
implements FacesWrapper<NavigationCase>
```
Provides a simple implementation of NavigationCase that can be subclassed by developers wishing to provide specialized behavior to an existing NavigationCase instance. The default implementation of all methods is to call through to the wrapped NavigationCase instance.

Usage: extend this class and push the implementation being wrapped to the constructor and use getWrapped() to access the instance being wrapped.

Since:

2.2

Constructor Summary

Constructors
Constructor and Description
`NavigationCaseWrapper()` Deprecated. Use the other constructor taking the implementation being wrapped.
`NavigationCaseWrapper(NavigationCase wrapped)` If this navigation case has been decorated, the implementation doing the decorating should push the implementation being wrapped to this constructor.
