Class DelegatingMetaTagHandler
- All Implemented Interfaces:
FaceletHandler
- Direct Known Subclasses:
ComponentHandler
,FaceletsAttachedObjectHandler
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.
