在模板外定义函数模板 class

Question

有点难以解释，但基本上，我想做这样的事情：

template <typename T>
class some{
    int hello();
};

//The method needs to be defined outside of the template class declaration and be able to use T defined in the template
int some::hello(){
    T* other = new T;
    T->doSomething();
}

我该怎么做？

Answer 1

给你：

template <typename T>
class some{
    int hello();
};

//The method needs to be defined outside of the template class declaration and be able to use T defined in the template
template<typename T>
int some<T>::hello(){
    T* other = new T;
    other->doSomething();
}
