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

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

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.
