Method Detail

getConverterback to summary
public Converter<T> getConverter()

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

Returns:Converter<T>

the converter.

getLocalValueback to summary
public Object getLocalValue()

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

Returns:Object

the local value.

getValueback to summary
public Object getValue()

Gets the value of this UIComponent. If validation failed, as indicated by javax.faces.context.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 requires a call through to UIComponent#setValueExpression, legacy tags will continue to work.

Returns:Object

the value.

setConverterback to summary
public void setConverter(Converter<T> converter)

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

Parameters
converter:Converter<T>

New Converter (or null)

setValueback to summary
public void setValue(Object value)

Set the value of this UIComponent (if any).

Parameters
