javax.faces.component
public interface: ValueHolder [javadoc | source]

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).
