我想在模板类方法中使用迭代器.这是我的代码:(testclass.h)
template<typename T, typename container>
class TestClassX
{
public:
void gen(typename container::iterator first );
};
和文件testclass.cpp:
template<typename T, typename container>
void TestClassX<T, container>::gen(typename container::iterator first)
{
}
当我尝试运行它时:
TestClassX<unsigned, std::vector<unsigned> > testx;
testx.gen(it);
我收到一个错误:
Error:undefined reference to `TestClassX<unsigned int, std::vector<unsigned int, std::allocator<unsigned int> > >::gen(__gnu_cxx::__normal_iterator<unsigned int*, std::vector<unsigned int, std::allocator<unsigned int> > >)'
我用的是mingw32 4.4
我想有一个类可以写入不同的容器,如std :: vector,std :: list,QVector或QList都有STL样式的迭代器.
