[Boost-users] Iterator over values of std::map<K, V>

Hi all, I have been browsing through the docs, but I couldn't find anything useful. Does Boost have a std::map::iterator adaptor which iterates over the values of the map only. That is, I would like to have an iterator of which operator*() function returns V, instead of std::pair. My data is stored in a std::map and I would to allow my users to iterate over the values. If it's not here, I'll make one myself. It shouldn't be that hard. Thanks in advance. Kind regards, John
