C++ method name as template parameter

Question

How do I make the method name (here some_method) a template parameter?

template
void sv_set_helper(T& d, bpn::array const&         


        

Answer 1

There is no such thing as a 'template identifier parameter', so you can't pass names as parameters. You could however take a member function pointer as argument:

template
void sv_set_helper(T& d, bpn::array const& v) {
   to_sv(v, ( d.*SomeMethod )());
}

that's assuming the function has a void return type. And you will call it like this:

sv_set_helper< SomeT, &SomeT::some_method >( someT, v );
