- javax.faces.context.Flash
- - javax.faces.context.FlashWrapper

All Implemented Interfaces:

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

Usage: extend this class and override getWrapped() to return the instance we are wrapping.

Since:

2.2
