[Engine-devel] Use java.util.Collection where possible?

Hi, I see that in some places in engine-core we use Java.Util.List, or even Java.Util.ArrayList as types of method arguments, while in the method code we do nothing besides iterating over the collection. I then found all kinds of usages like this: x.foo(new ArrayList<MyType>(myMap.values())); As you can see need to instantiate a new ArrayList in order to use the values of the map in method foo. Do you see any reason why not change the argument type (at method signature) to Collection in such places, where possible? Yair
