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 . |
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). |
Object getLocalValue()
Return the local value of this UIComponent
(if any), without evaluating any associated
ValueExpression
.
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, jakarta.faces.el.ValueBinding)
requires a call through to UIComponent.setValueExpression(java.lang.String, jakarta.el.ValueExpression)
, legacy tags
will continue to work.
void setValue(Object value)
Set the value of this UIComponent
(if any).
