class Event{
public:
      enum EventType { A_1, A_2, A_3, A_4};

      Event(EvtType type = A_1, double etime = 0.0)
           : _type(type)
           , _etime(etime)
      {}

      EventType get_Type() const { return _type; };
      double get_Time() const { return _etime; }

protected:
      EventType _type;
      double _etime;
};

struct EventLess{

    bool operator()(const Event& lhs, const Event& rhs) const
        {
         return (lhs.get_Time() > rhs.get_Time());
        }
};

我可以创建最小优先级队列,如下所示

 priority_queue<Event, std::vector<Event>, EventLess> q;

但是,如果我有另一个类,如:

class Event1
{
public:
     enum EventType { disruption_1, disruption_2};

     Event(EvtType type = disruption_1, double …
