Inserting a variadic argument list into a vector?

Question

Forgive me if this has been answered already, as I couldn\'t find it...

Basically I have an object that needs to take a variadic argument list in it\'s constructor

Answer 1

Another way to do it:

#include 
#include 

using std::vector;

template 
void variadic_vector_emplace(vector&) {}

template 
void variadic_vector_emplace(vector& v, First&& first, Args&&... args)
{
    v.emplace_back(std::forward(first));
    variadic_vector_emplace(v, std::forward(args)...);
}

struct my_struct
{
    template 
    my_struct(Args&&... args)
    {
        variadic_vector_emplace(_data, std::forward(args)...);
    }

    vector& data() { return _data; }

private:
  vector _data;
};


int main()
{
    my_struct my(5, 6, 7, 8);

    for(int i : my.data())
      std::cout << i << std::endl;
}
