[rules-users] [rule-users]RunTime polypmorphic support in 3.0.6?

[Edson Tirelli]

   Hi,

   Sorry, I did not understood your question, but I guess you are asking
about facts matching ObjectTypeNodes of super classes. The answer is yes, it
works:

public class A {}
public class B extends A {}
public class C extends A {}

   If you have a rule saying

rule XXX
when
   A ()
then
  // do something
end

   The rule will fire for all facts of class A, B and C, as B and C are
subclasses of A. It is like if you did an "instanceof" to know what rules
will fire and what will not.

   Hope that is what you were asking.
