Hello everybody!
Please don't blame for beeing foolish - I'm using the iterator-adapter class for the first time. I converted a standard iterator from a std::vector with the iterator_adapter stuff into another class random_set_iterator. But at certain points in my programm I need the random_set_iterator converted back to the original iterator class from the vector class. I noticed the base()-function which basically does the job, but I think there should be a more elegant and clearer way to do it. Am I wrong or shouldn't an adapted iterator almost always be convertible to it's base iterator?
It shouldn't. Implicit conversions are generally dangerous; there's no good reason to allow one here.
I'm sure, it should not hard to implement somthing like this, but how?
You can easily add an operator base_iterator_type() const to random_set_iterator, but we (the authors of iterator_adaptor) don't recommend it. -- Dave Abrahams Boost Consulting www.boost-consulting.com
