Re: [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.

Off the top of my head, and untested: typedef std::map::value_type pairkv; boost::make_transform_iterator( map, boost::bind(&pairkv::second, _1 ) ) will get you a value iterator; Jeff Flinn
