Re: [Boost-users] How to call STL map.second in boost lambda?

I have a for loop which pass the map.second to a function, like this: class A; typedef map<int, A*> MyMap;

sortY(A& a);

for (MyMap::iterator iter = map.begin(); iter != map.end(); ++iter) { A *a = (*iter).second;

sortY(*a); }

how can I translate the above for() loop into for_each and use boost lambda?

I didn't test the following, but it should work :) #include <boost/lambda/lambda.hpp> #include <boost/lambda/bind.hpp> using boost::lambda::_1; using boost::lambda::bind; std::for_each(map.begin(), map.end(), bind(&sortY, *bind(&MyMap::value_type::second, _1))); KevinH -- Kevin Heifner heifner @ ociweb.com http://heifner.blogspot.com Object Computing, Inc.
