| JFunction | | final public class JFunction extends JConstructor implements Function(Code) | | A JFunction is a function defined by a java method. E.g., if 'Max'
is a constant term (Max itself being an instance of a class Person),
and father() is a method defined in this class returning another
instance, then we can build a JFunction based on the method
father() with a well defined semantic: the term father('Max')
can be simplified to a constant term that wrappes the result of invoking
father() with the parameter array {Max} (and that is me, Jens :-)).
In version 3.2, session support has been added. The last parameter (found in the wrapoped method)
is treated separately if its type is Session (or a subclass of session). Then this parameter is used
to pass a session reference at query time to the function or predicate!
