stxxl supports streaming model of data processing. stxxl data can either processed iterating through (e.g. using stxxl::for_each ), or converting stream mode (e.g. using streamify() such stream transforms can composed efficient processing. stream results can converted iterators using materialize() . i have bunch of stream transforms, want apply input stream. however, not need store result in output "container". need materialize -like function drives stream without taking output iterators - stxxl::for_each . there such similar function in stxxl? naturally, can write custom "do-nothing"-output-iterators , pass these materialize() , wondering if there more elegant solution. there stxxl::stream::discard . takes stream , throws away results.
