Not quite. I am aware of various iterator implementations, including yours. What I wanted is an example of implementation Michael suggested, because he said that his variant is better then mine, so a wanted to look at it to compare. Do I understand correctly that you are speaking about this article: http://opensoft.homeip.net/articles/iterator_pattern.pdf ? As far as I understand, since iterators described in the article do not have the concept of a current item, they also do not have concept of an index, and hence are not relevant in the context of this discussion. -- Alexander S.
