Interface FaceletHandler

BehaviorHandler, ComponentHandler, CompositeFaceletHandler, ConverterHandler, DelegatingMetaTagHandler, FaceletsAttachedObjectHandler, MetaTagHandler, TagHandler, ValidatorHandler
public interface FaceletHandler

This is the root class for markup elements in Facelets VDL. Facelets is XHTML, and XHTML is XML, and the root unit of abstraction in XML is the element. A FaceletHandler instance represents an XML element at runtime. Two direct implementations exist to embody the contract for more specific behavior.

CompositeFaceletHandler
A container for other FaceletHandlers
TagHandler
The foundation class for FaceletHandlers associated with markup in a Facelet document.
