Hi,

just wondering what the mood in Boost.Iterator is for new features? At work we recently found use for an orbiting iterator, specifically a circular one, which effectively wraps at the start/end of a bounded range. (The domain is digital signal processing.)

That sounds like what CGAL calls a Circulator; c.f. http://doc.cgal.org/ latest/Circulator/classCirculator.html

Sounds to me like a ring_view - (ring_view?) which has been discussed for a long time.

I couldn't find anything on this with a cursory search, could you link to something?

Thanks, cheers. Jeremy

Must be useful to some people, so yes. (Needs tests, an example and docs of course to add to Boost).

We could bikeshed about the name? Orbiting iterator, ring_iterator, circulator, never-ending ... ;-) Paul --- Paul A. Bristow Prizet Farmhouse Kendal UK LA8 8AB +44 (0) 1539 561830

At my work, we call the iterator version circular_iterator

My thoughts exactly, good to know I'm on the right track, thanks. Jeremy

So now the question remains: is there a maintainer of Boost.Iterator that, in principle, wants this? Who is/are the maintainer(s)? I found reference to a user jeffrey.hellrung, is that current?

Cheers.

By looking at the PR and commit histories, Boost.Iterator is not being maintained. I would like to request that the library be added to the CMT list. michael -- Michael Caisse Ciere Consulting ciere.com
