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 binding expression, and support conversion between String and the model tier data's native data type.

Method Summary

javax.faces.convert.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 ValueBinding.
java.lang.Object	getValue() Gets the value of this UIComponent.
void	setConverter(javax.faces.convert.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).

Method Detail

getLocalValue

public java.lang.Object getLocalValue()

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

getValue

public java.lang.Object getValue()

Gets the value of this UIComponent. First, consult the local value property of this component. If non-null return it. If non-null, see if we have a ValueBinding for the value property. If so, return the result of evaluating the property, otherwise return null.

setValue

public void setValue(java.lang.Object value)

Set the value of this UIComponent (if any).

Parameters:

value - The new local value

getConverter

public javax.faces.convert.Converter getConverter()

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

setConverter

public void setConverter(javax.faces.convert.Converter converter)

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

Parameters:

converter - New Converter (or null)
