Thanks a lot both. Transform Iterator did the trick. Kind regards, John On Nov 29, 2007 9:04 PM, Niels Aan de Brugh <niels@invalid.org> wrote:

Does Boost have a std::map<K, V>::iterator adaptor which iterates over
useful. the
values of the map only.
What about using a boost::transform_iterator<>? Docs at:
http://boost.org/libs/iterator/doc/transform_iterator.html
You'd have to supply it with a function object that returns the 'second' member variable of the pair, e.g.
struct get_pair_value { template< typename K, typename V > V operator()( std::pair< K, V > const& pr ) { return pr.second; } };
Or you could use Boost.Lambda.
