Interface FaceletHandler

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.
