Hi all,
Why isn't there a mapped_type/key_type iterator adaptor in boost? (Just in case it's not clear, something which allow one to iterator over the keys or the mapped-values of a map/multimap.) I would think this is a pretty common need.
Do
http://www.boost.org/doc/libs/1_43_0/libs/range/doc/html/range/reference/ada...
and
http://www.boost.org/doc/libs/1_43_0/libs/range/doc/html/range/reference/ada...
address your needs? Not exactly iterator adaptors though...

I don't know. I'm interested in using a mapped_type iterator adaptor with Thomas Becker's any_iterator (see http://thbecker.net/free_software_utilities/type_erasure_for_cpp_iterators/a...). With any_iterator, I can do the following any_iterator<...> it_any = my_mapped_type_iterator_adaptor(map_instance.begin()); How would I go about doing that with ranges? Thanks, -Mostafa
