Iterator
Description
The Iterator allows you to easily iterate through all objects in an ObjectList. An ObjectList stores all objects of a given class (and all derivatives). To start iterating, you need the first element in the ObjectList. This gets returned by ObjectList<ClassName>::begin().
Example
The following example uses the class-tree below.
new A1(); new A1(); new A1(); new A3(); new A3B1(); new A3B1C1(); int count = 0; for (Iterator<BaseObject> it = ObjectList<BaseObject>::begin(); it; ++it) count++; std::cout << "BaseObject: " << count << std::endl; count = 0; for (Iterator<A1> it = ObjectList<A1>::begin(); it; ++it) count++; std::cout << "A1: " << count << std::endl; count = 0; for (Iterator<A3B1> it = ObjectList<A3B1>::begin(); it; ++it) count++; std::cout << "A3B1: " << count << std::endl; /* return: BaseObject: 6 A1: 3 A3B1: 2 */
