Template container iterator base class (abstract).
Each container implementation has a matching iterator. This class defines the basic interface for any iterator implementation.
Please note that TIterator::next and TIterator::previous always return the current iterator item and switch to the new item afterwards. This allows iteration loops in this style:
TLinkedList<int> myList; ... TLinkedListIterator<int> iter (myList); while (iter.done () == false) { int myInt = iter.next (); }
