 package javax.faces.component;
 
 

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.

 
 
 public interface ValueHolder {
 
 
     // -------------------------------------------------------------- Properties
 
    

Return the local value of this UIComponent (if any), without evaluating any associated javax.el.ValueExpression.

 
     public Object getLocalValue();


    

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 javax.el.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(java.lang.String,javax.faces.el.ValueBinding) requires a call through to UIComponent.setValueExpression(java.lang.String,javax.el.ValueExpression), legacy tags will continue to work.

 
     public Object getValue();


    

Set the value of this UIComponent (if any).

Parameters:
value The new local value
 
     public void setValue(Object value);



    

Return the javax.faces.convert.Converter (if any) that is registered for this UIComponent.

 
     public Converter getConverter();


    

Set the javax.faces.convert.Converter (if any) that is registered for this UIComponent.

Parameters:
converter New javax.faces.convert.Converter (or null)
    public void setConverter(Converter converter);
