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.

Hi,
I have a query. am using Drools 3.0.6.
i have a ObjectA and ObjectB and ObjectC.
ObjectB and OBjectC inherits Object A.
am using seperate drl file for objectA, objectB and objectC.
i need to use the DRL pertain to ObjectA when validate ObjectB and ObjectC.
So when i check the object say ObjectB which i asserted in working memory, can i assume that ObjectA also available implitcitly?
The rules associated with ObjectA will fire when I assert just OBjectB?
Please clarify
Thanks and Regs,
Basha
