Question

template  class myclass

    {
       // Do interesting stuff

};
         


        

Answer 1

Can try something like following :

#include 

template
struct all_same : std::true_type
{};

template
struct all_same
    : std::integral_constant{} && all_same{}>
{};


template  class myclass
{
    public:
    template 
     typename std::enable_if::type mymethod(Args... args)
    {
        static_assert(all_same{}, 
                      "Not all args as Double");
    }
};
