[209] C++ 표준 문법만 가지고 C++ 빌더처럼 객체의 멤버함수 포인터로 이벤트 호출하는 법 2
한재윤 [helloman] 28216 읽음    2010-04-03 21:16
안녕하세요..
시간이 남아서 작업을 추가했습니다.
일단 __fastcall로 되어 있는 이벤트 핸들러도 동시에 처리합니다.
그리고 shared_ptr의 초기화도 지원합니다.
이벤트는 옵저버를 shared_ptr이 아니라 weak_ptr로 가지고 있게 됩니다.
즉 옵저버 연결이 유지되어도 객체의 생명주기가 다 되어서 객체가 삭제될 수 있습니다.
그러나 weak_ptr이므로 최소한 객체의 유효여부는 알 수 있으므로 사라진 객체에 대해서
멤버함수 콜을 하지 않습니다.
이러한 기능 추가를 위해서 사용법이 바뀐 것은 없습니다.
그냥 아래 글에서 설명한 방법으로 사용하시면 됩니다.
