Class DelegatingMetaTagHandler
java.lang.Object
javax.faces.view.facelets.TagHandler
javax.faces.view.facelets.MetaTagHandler
javax.faces.view.facelets.DelegatingMetaTagHandler
- All Implemented Interfaces:
- FaceletHandler
- Direct Known Subclasses:
- ComponentHandler, FaceletsAttachedObjectHandler
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.

apply
