[traits] Type of class of member function pointer
Dear all, perhaps more out of exercise, but does any of you know whether it is possible to get to the type of the class of a member function pointer? I.e., to somehow get to type T in "R (T::*)()"? (in this particular case, a member function without arguments in class T returning R)? Thanks a lot, Rutger

Look at the FunctionTypes library. In Christ, Steven Watanabe

I've skimmed over the doc, but still not found the weapon. :-( B/Rgds Max

For member function pointers, the class is treated as the first argument. boost::mpl::at_c<parameter_types<R(T::*)(), boost::mpl::identity<> >, 0>::type In Christ, Steven Watanabe

Cool! Thanks. I'll have a closer look at the doc and try to dissect the expression. B/Rgds Max
