Question

i want a specialize template in a pointer-to-member-function case. Is there a way to detect this? right now i declare struct isPtrToMemberFunc, then add an extra template (class TType=void) to each class (right now just 1) and specialize the extra template to see if its isPtrToMemberFunc. Is there a way to detect this automatically? if not is my current method the best solution?

Answer 1

There is a way, but it includes that you repeat your specialization for each and every number of arguments and const/volatile modifiers for those member functions. An easier way to do that is to use boost.functiontypes which does that for you:

template<typename T> void doit(T t) {     if(boost::function_types::is_member_function_pointer<T>::value) {         std::cout << 'it is';         // ...     } else {         std::cout << 'it is not';         // ...     } }
