overloading/defining operator<
In order to use a class with std::map, a comparison function must be defined in order to sort class instances. Either a functor can be used in the map CTOR, or the operator< should be defined for the class. If I define the operator< in the class: - should this return whether this < other or other < t... 20 Dec 2007 12:32
