+
+The !ObjectListIterator of a given class T can iterate exactly through all objects of class T and inheritors. The only way to create such an iterator is by calling one of [wiki:ObjectList ObjectLists] functions begin, end, rbegin or rend, where the !ObjectList has to be of the same T as the !ObjectListIterator.
+
+Another way to iterate through object-lists is by using [wiki:Iterator]. !ObjectListIterator however is much more performant as it knows about the right class an therefore needs no dynamic-cast. That's why you should always remember:
+
+'''Important''': Always use !ObjectListIterator instead of Iterator if you know which class you want to iterate through.
+
+== Example ==
+{{{
+for (ObjectListIterator<myClass> it = ObjectList<myClass>::begin();
+                                 it != ObjectList<myClass>::end(); ++it)
+{
+    it->someFunction(...);
+    myClass* myObject = *it;
+}
+}}}
