I notice that upon executing a query with the EM, it returns a
collection list of type "DelagatingResultList" can I just use that in
the business logic of my app, or should I copy it into a standard
ArrayList first?
Generally, any type of XXXList<Foo> that you get from "someone else's
code" should be treated (not copied!) as a List<Foo>. Unless you know
that the behavior you need is only in XXXList and not in List. So in
your Java code,
List<Foo> result = fooQuery.getResultList();
So carefully look at your requirements, but in general just use the
List<Foo> behavior until you find you need something more. And then
ask here to see if there's a better way.
