[rules-users] Any form of "groub by" or "distinct" in accumulate/collect ?

Hello. Perhaps that my question has few sense or none... I've an object graph with say A, B and C. A has one or many B, that has one or many C. I can navigate through the relations between my objects in both direction. For example, I can do fo any instance of C : c.b.a (or c.getB().getA())... My initial input facts or only C objects, and I'd like to identify all the distinct A instances, and insert them into my working memory, as they participate to global rules. I've been looking for some forms of accumulate or collect, but I've not found a correct way to do it. Some help ? Thanks Regards. -- View this message in context: http://drools.46999.n3.nabble.com/Any-form-of-groub-by-or-distinct-in-acc... Sent from the Drools: User forum mailing list archive at Nabble.com.
