() 을 재정의해서, () 을 필요한 만큼 겹겹이 호출해서 접근하도록 했다.
아래 예제:202510200053 참고.
ZtCObjtChain<TDataNow, ZCEmpty>::TypeChainLast 을 추가해,
■ 아래 멈버 함수를 추가하고
template<typename TDataHere>
TypeChainNow & operator= (const TDataHere& AR_Data)
{ return *this;}
TypeChainNow & operator= (const TypeData & AR_Data)
{ mo_TypeVar=AR_Data; return *this;}
이를 활용하는 SetDataRecur()
template<int TTypNo, typename TDataHere>
bool SetDataRecur(const TDataHere& AR_Data)
를 추가. 그래서 이런 예제가 가능하다.
typedef ZtCObjtChain
<
char , ZtCObjtChain<
string, ZtCObjtChain<
double, ZtCObjtChain<
int ,
ZCEmpty > > >
> ZCObjtChain; ZCObjtChain VO_ZCObjtChain;
VO_ZCObjtChain="New3 Str";
VO_ZCObjtChain='B';
VO_ZCObjtChain.SetDataRecur<4>('D');
VO_ZCObjtChain.SetDataRecur<3>(string("New3 Str"));
VO_ZCObjtChain.SetDataRecur<2>(0.8);
VO_ZCObjtChain.SetDataRecur<1>(9999);
와, 멤버 변수 변경이 이렇게 깔끔하게 될 수 있다니...
C++ 진짜 멋지다!
