[Boost-users] Re: indirect_iterator of reverse_iterator

Thomas Matelich writes:

Hello,

I'm a little behind the times and am trying to port my old iterator_adapters code to use the new library (1.32). We have a class which is little more than a wrapper around a vector, and I am having a heck of a time with setting its typedef for reverse_iterator and const_reverse_iterator. I just can't get const_reverse_iterator to do assignment and comparison with reverse_iterator.

I've tried to make indirect_iterators out of the native reverse iterators,

That almost certainly won't work, because the native reverse_iterator usually won't play nicely with the native const_reverse_iterator.

using boost::reverse_iterators of indirect_iterators

What happens when you do that? (code, error messages) Have you verified that the const and mutable indirect_iterators interoperate the way you'd like?

and a number of more complicated combinations of the 3. No matter which I try I get errors about the const_reverse_iterator not playing nicely with the reverse_iterator. I think I've read everything on the list archives about indirect_iterator, but perhaps I missed something. I'm going to try my code on g++ (currently using VC 7.1) and then work on a complete example, but I thought I'd throw this out and see if someone can quickly answer it.

No obvious ideas, sorry. -- Dave Abrahams Boost Consulting www.boost-consulting.com
