Extension function interface. Extension functions are grouped into
Functions objects, which are installed on
JXPathContexts using the
JXPathContext.setFunctions()
call.
The Function interface can be implemented directly. However,
most of the time JXPath's built-in implementations should suffice.
See ClassFunctions and
PackageFunctions .
