public interface ValueHolder
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 Summary | |
|---|---|
Converter |
getConverter()
Return the Converter (if any)
that is registered for this UIComponent. |
Object |
getLocalValue()
Return the local value of this UIComponent (if any),
without evaluating any associated ValueExpression. |
Object |
getValue()
Gets the value of this UIComponent. |
void |
setConverter(Converter converter)
Set the Converter (if any)
that is registered for this UIComponent. |
void |
setValue(Object value)
Set the value of this UIComponent (if any). |
| Method Detail |
|---|
Object getLocalValue()
Return the local value of this UIComponent (if any),
without evaluating any associated ValueExpression.
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(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.
void setValue(Object value)
Set the value of this UIComponent (if any).
value - The new local valueConverter getConverter()
Return the Converter (if any)
that is registered for this UIComponent.
void setConverter(Converter converter)
Set the Converter (if any)
that is registered for this UIComponent.
converter - New Converter (or null)
