- jakarta.el.Expression
- - jakarta.el.ValueExpression
  - - org.omnifaces.el.ValueExpressionWrapper

All Implemented Interfaces:

FacesWrapper<ValueExpression>, Serializable

Direct Known Subclasses:

CachingValueExpression
```
public class ValueExpressionWrapper
extends ValueExpression
implements FacesWrapper<ValueExpression>
```
Provides a simple implementation of ValueExpression that can be sub-classed by developers wishing to provide specialized behavior to an existing ValueExpression instance. The default implementation of all methods is to call through to the wrapped ValueExpression.

Usage: extend this class and provide the instance we are wrapping to the overloaded constructor.
