I was struggling with const correctness and iterator adaptors. At first I was
using iterator_facade. I found it difficult to get dereference to work
correctly. After changing to iterator_adaptor I got things working. I'm
wondering if the approach I used is "correct".
I include the whole class here, because it isn't really very big.
I was using a Ring class which contains an iterator, which is
If a Ring const& is passed I had problems with dereference.
The changes I made to cycle_iterator fix this were:
1) Add templated conversion constructor to cycle_iterator, to allow implicit
conversion of cycle_iterator -> const cycle_iterator.
2) Include both
const reference dereference() const
(likewise for operator)
So, do my changes constitute a "correct" approach to making interoperable
iterators using boost::iterator_adaptor?
