Probably a class that has operators unary *, ++ and possibly -- defined, where the first one returns a reference to the underlying T object, the second advances the iterator to the next element in the container and the last one advances the iterator backwards.

Or, if you're using some standard container, just the return value of yourContainer.begin() or yourContainer.find().

If you elaborate on your question you can get a better answer. For example, what container are you using? What's expecting a generic iterator?
