big change in ObjectList: separated the class into a non-template base and a template wrapper for the base. this also changes the Iterator, there is now a non-template IteratorBase. this brings much more flexibility, like iterating through all objects of a given identifier without knowing the type. however this needs a dynamic_cast, which isn't quite optimal, but I think there are much worser things than that out there.
there isn't much you have to know about this, except there is no more ObjectList<myClass>::start() function but a ObjectList<myClass>::begin() to be more STLish. another thing: ObjectList<myClass>::end() points now to the element _after_ the last element, so it's possible to iterate in a for-loop until (it != ObjectList<myClass>::end()). the reason is the same as above. however, (it) as a boolean still works perfectly fine. |
