Same name is ok, same signature is not. You have to make sure that two methods in different roles don't clash, signature-wise (name+parameter types). > Is it possible to get an instance of each mixin as a Human Composite ? That question does not compute. What exactly do you want to accomplish? Assume I have two mixins with the same method's signature. Assume that my human wants to speak(). I could do in particular do so: HumanComposite humanDeveloper = (HumanComposite)new DeveloperMixin(); Or HumanComposite humanDeveloper = (HumanComposite)new AlumniMixin(); That's usual polymorphic declaration. I was wondering if there were possible to achieve let's say "horizontal" polymorphism with a help of factories that are provided by Qi4j or other Qi4j mechanism that I don't know, but as you say it's impossible to have same signatures' names of methods in a same composite. Thanks for your fast reply. /Pawel _______________________________________________ qi4j-dev mailing list [email protected] http://lists.ops4j.org/mailman/listinfo/qi4j-dev
