ValueHolder is an interface that may be implemented by any concrete UIComponent that wishes to support a local value, as well as access data in the model tier via a value expression, and support conversion between String and the model tier data's native data type.

Method from javax.faces.component.ValueHolder Summary:
getConverter,   getLocalValue,   getValue,   setConverter,   setValue

Method from javax.faces.component.ValueHolder Detail:
public Converter getConverter() Return the Converter (if any) that is registered for this UIComponent .
public Object getLocalValue() Return the local value of this UIComponent (if any), without evaluating any associated ValueExpression .
public Object getValue() Gets the value of this UIComponent . First, consult the local value property of this component. If non-null return it. If null, see if we have a ValueExpression for the value property. If so, return the result of evaluating the property, otherwise return null. Note that because the specification for UIComponent#setValueBinding requires a call through to UIComponent#setValueExpression , legacy tags will continue to work.
public void setConverter(Converter converter) Set the Converter (if any) that is registered for this UIComponent .
public void setValue(Object value) Set the value of this UIComponent (if any).
