C++ Code Clarification Needed..
- by ke3pup
Hi guys
I'm trying to understand what the code below says:
struct compare_pq;
struct compare_pq {
bool operator() (Events *& a, Events *& b);
};
std::priority_queue<Events *, std::vector<Events *>, compare_pq> eventList;
i looked at what priority_queue is and how its declared but can't quit understand what compare_pq is doing in the priority_queue eventList. Also what does operator() do since i've never seen *& before and empty operator overloading operator()!
any help would be appreciated. Thank you
