Re: [Boost-users] Newbie question on filter_iterators

I think you'll need to use something like:

for(filter_itr f(i.begin(), i.end()); f != filter_itr(i.end()); ++f)

Or use make_filter_iterator.

filter_iterator doesn't have an assignment operator,

Whoa there, it certainly does! All iterators are required to support assignment. It doesn't have an implicit conversion from the underlying iterator type, though, which rules out using copy initialization from anything other than another filter_iterator.

you have to go through the relevant constructor (see http://www.boost.org/libs/iterator/doc/filter_iterator.html#filter-iterator-...)
