org.apache.myfaces.trinidadinternal.ui.ElementRenderer
public class ElementRenderer
Renderer implementation that can output elements.
This base implementation outputs no attributes; clients
must override renderAttributes()
. It will
output the start and element tags, based on the return
value of getElementName()
.
