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.
| Modifier and Type | Method and Description |
|---|---|
Converter |
getConverter()
Return the
Converter (if any)
that is registered for this UIComponent. |
java.lang.Object |
getLocalValue()
Return the local value of this
UIComponent (if any),
without evaluating any associated ValueExpression. |
java.lang.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(java.lang.Object value)
Set the value of this
UIComponent (if any). |
java.lang.Object getLocalValue()
Return the local value of this UIComponent (if any),
without evaluating any associated ValueExpression.
java.lang.Object getValue()
Gets the value of this UIComponent. If validation
failed, as indicated by
FacesContext.isValidationFailed()
returning true, always return the local value.
Otherwise, 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(java.lang.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)
