Question

I have a template class that I have some specializations for.
But the next specialization is a template itself. How do you specify this:

template<typename T>
class Action
{
    public: void doStuff()  { std::cout << "Generic
"; }
}

// A specialization for a person
template<>
class Action<Person>
{
    public: void doStuff()  { std::cout << "A Person
";}
}


// I can easily specialize for vectors of a particular type.
// But how  do I change the following so that it works with all types of vector.
// Not just `int`
template<>
class Action<std::vector<int> >
{
    public: void doStuff()  { std::cout << "A Generic Vector
";}
}

template <typename T>
class Action<std::vector<T>> {
public:
  void doStuff() { std::cout << "A Generic Vector
"; }
};
