javax.faces.view.facelets
public abstract class DelegatingMetaTagHandler extends MetaTagHandler
Enable the JSF implementation to provide
the appropriate behavior for the kind of MetaTagHandler
subclass for each kind of element in the view, while providing a
base-class from which those wanting to make a Java language custom
tag handler can inherit. The JSF runtime provides the implementation
of getTagHandlerDelegate()
for the appropriate subclass.
