[VC6]std::vector派生类无法调用std::vector的解决方法

template<class _Ty, class _A = std::allocator<_Ty> >
class CTestVector : public std::vector<_Ty,_A >
{
public:
void clear()
{
std::vector<_Ty,_A >::clear();
}
};

调用代码
CTestVector<int> vv;
 vv.clear();

出差提示:
'std::vector<int,class std::allocator<int> >::clear' : illegal call of non-static member function

解决方法

template<class _Ty, class _A = std::allocator<_Ty> >
class CTestVector : public std::vector<_Ty,_A >
{
typedef std::vector<_Ty,_A > PARENT;
public:
void clear()
{
PARENT::clear();
}
};
