Class ValueBindingToValueExpression

java.lang.Object

javax.el.Expression

javax.el.ValueExpression

org.apache.myfaces.el.convert.ValueBindingToValueExpression

All Implemented Interfaces:

Serializable, StateHolder

public class ValueBindingToValueExpression
extends javax.el.ValueExpression
implements StateHolder

Wraps a ValueBinding inside a ValueExpression. Also allows access to the original ValueBinding object. Although ValueExpression implements Serializable, this class implements StateHolder instead. ATTENTION: If you make changes to this class, treat ValueBindingToValueExpression accordingly. See javax.faces.component._ValueBindingToValueExpression
