This document describes iterators within the context of doubly linked lists.
Iterators provide an easy way of cycling through the elements of a doubly linked list, using the post increment operator ++ and the post decrement operator -- . They avoid the need to access the inner detail of link objects and list headers.
An iterator is an instance of the templated class TDblQueIter<class T> . The class provides the behaviour for moving through the elements of a specific list. An iterator maintains a pointer to the current element in the list. The current element can be any element in the list.
