Detailed Description

template<typename T>
struct has_attributes< T, typename Void< decltype(T::attributes::name[0])>::type >

has_attributes check if a type has defined an internal structure with attributes

struct test_has_attributes
{
    struct attributes
    {
        static const std::string name[2];
    };
};

const std::string test_has_attributes::attributes::name[]={"attributes1","attributes2"};

{
};

return true if T::attributes::name[0] is a valid expression and produce a defined type
