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.)

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

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.

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
