Description

A barebone event manager written in C++, updated to use the right standard containers, and extended to support different key types

Sample Usage

#include "EventManager.h"

class A
{
public:
  void SomeEvent(EventParams& args)
  {
    args.Count();
  }
};

class B
  : public A
{
public:
  void SomeEvent2(EventParams& args)
  {
    args.Count();
  }
};

int main(int, char**)
{
  EventManager<std::string> man;

  B bInst;

  man.RegisterEvent("event1", &bInst, &B::SomeEvent2);

  // trigger event with class registered
  man.OnEvent("event1");

  // unregister and trigger event (which won't fire)
  man.UnregisterInstance(&bInst);
  man.OnEvent("event1");

  // explicitly register bInst as class A
  man.RegisterEvent<A>("event2", &bInst, &B::SomeEvent);
  man.OnEvent("event2");

  return 0;
}
