Hi! Is there an easy way to use the exact type of what boost::bind(...) returns? The example above sheds some light of the source of this question. It would be much better (actually this is what bind is for, isn't it?) if I didn't have to define the plus_5 struct in order to be able to use transform_iterator. I wrote it in the comment what I'm thinking about. I could delve deeply into the bind header files and try to explicitly find what the exact class definition is, but I suspect it would not be too easy. Anyway, I may be forced to do
//------- *** ---------------------- //typedef transform_iterator< bind_type<plus<5>, _1, 5>, int* > Iterator; // how to easily get the return type of bind(plus<5>(), _1, 5) // in compilation time? //------- *** ------------------------
Try: typedef transform_iterator<function<int (int)>,int*> Iterator; (You may need to use function1<...> depending on your compiler) http://www.boost.org/doc/html/function.html Chapter 4.
