Our plan is to add the macro to the most parent class, isn't it?

[tasak, 2015/08/25 03:54:41]

Done.

 public:
     static PassOwnPtr<EventFactory> create()
     {
         return adoptPtr(new EventFactory());
     }
 
     PassRefPtrWillBeRawPtr<Event> create(const String& eventType) override;
 };
 
 }
