How to define a template class as a friend of a common class in C++

看情况.

如果两者的模板参数一致,那么就这样:

1. template<typename T>
   
2. class Test
   
3. {
   
4. friend class Friendclass<T>;
   
5. // .....
   
6. };

复制代码

如果不一致,那就这样:

1. template<typename T>
   
2. class Test
   
3. {
   
4. template<typename T1>
   
5. friend class Friendclass<T1>;
   
6. // .....
   
7. };

Thank you, but I mean in a common class, not template class.

class Test
{
template<typename T1>
friend class Friendclass<T1>;
// .....
};
