Re: [Boost-users] iterator_facade and distance()

Hi Dave, Thanks for your email.

Not unless yours is a random access iterator.  Is it?

Its a forward iterator. Changing it to a random access iterator solves it indeed. This is my first iterator that I am writing, but why is it not possible to implement a custom distance method for forward iterators? Am I doing something conceptually wrong? Or should I specialize the std::distance() function? Thank you, Andrej
