[Modeling] Modeling an Agent Class- register your opinion
Mon, 23 Jun 2003 11:16:59 +0200
I think we all agree that interaction between agents can be
IMPLEMENTED inside it's methods. Don't you?
That it is to say, a method m1 of an agent A1 is called and then
it calls a method m2 in an agent A2. Thus, if its role change we
can not delete this call. We can use an if statement based on the
roletype, but what happens if a new roles appear?
