+<concept id="GUID-4FB4CAD4-52BD-5DC1-9B20-34DA77F70A9D" xml:lang="en"><title>Iterators</title><shortdesc>This document describes iterators within the context of doubly
+linked lists.</shortdesc><prolog><metadata><keywords/></metadata></prolog><conbody>
+<p>Iterators provide an easy way of cycling through the elements of a doubly
+linked list, using the post increment operator<codeph>++</codeph> and the
+post decrement operator<codeph>--</codeph>. They avoid the need to access
+the inner detail of link objects and list headers.</p>
+<p>An iterator is an instance of the templated class <codeph>TDblQueIter&lt;class
+T&gt;</codeph>. 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.</p>
