리눅스에서 상속관련 질문입니다.
글쓴이: jb0730 / 작성시간: 화, 2013/02/05 - 2:54오후
전체적인 내용을 요약을 한다면은
IWorkerPool 의 protected로
int _total_thrcount;
Type_Interface_Worker **_threads;
선언을 하여주었습니다.
후에 WorkerPool 에서 IWorkerPool을 상속을 받습니다.
그렇게 하여서 WorkerPool.inl파일에서 상속을 받은 _total_thrcount를 사용을하는데
was not declared in this scope 에러가 나타납니다..
질문) 제 생각으로는 상속에 문제사항이 없다고 생각합니다 하지만 에러 메시지가 나타나서 질문올립니다.
꼭 답이아니더라도 어떠한형식으로 구글에서 검색을 해야 하는지 등이라도 알려주시면 감사하겠습니다.
구글링을 해보았는데 해당하는 문제점에 대해서 찾을수가 없었습니다.
또한 밑에쪽에서 expected class-name before ‘class’ 오류 메시지가 나타나는데 저부분은 ACE 프레임웤에서 에러나는 부분입니다.
ACE는 정상적으로 설정하여서 설치하였습니다. 저쪽에서 오류가 날수있는 상황이 아니라고 믿고있습니다.
저 오류에 대해서도 아신다면은 부탁드립니다...
질문하는 부분들은 찾아본후에 찾을수 없고 방향조차 찾기가 어렵습니다 잘부탁 드립니다.
IWorkerPool 헤더 파일입니다.
namespace HEMS_CENTER {
template<class Type_Interface_Worker, class Type_task>
class IWorkerPool {
public:
IWorkerPool() {
}
IWorkerPool(int threadCount) { }
virtual ~IWorkerPool() {
if (_threads) {
for (int i = 0; i < _total_thrcount; i++) {
_threads[i]->stop();
delete _threads[i];
}
}
delete [] _threads;
}
virtual int runAll() {
for (int i = 0; i < _total_thrcount; i++) {
_threads[i]->activate();
}
return 0;
}
virtual int distribute_task(Type_task *task)=0;
protected:
int _total_thrcount;
Type_Interface_Worker **_threads; // worker array;
};
}
#endif여기가 상속받는 클래스 입니다.. IWorkerPool의 내용을 상속받습니다.

}에러메시지 부분입니다...
