SFINAE to check for inherited member functions http://stackoverflow.com/questions/1966362/sfinae-to-check-for-inherited-member-functions iostream template typename T typename Sig struct has_foo template typename U U struct type_check template typename V.. foo struct B A int main using namespace std cout boolalpha has_foo A void A value endl true cout boolalpha has_foo B void B value.. boolalpha has_foo A void A value endl true cout boolalpha has_foo B void B value endl false So is there a way to test for inherited..
