    13 list.</shortdesc><prolog><metadata><keywords/></metadata></prolog><conbody>

    14 <p>An element in a doubly linked list can be any kind of object. To allow

    15 an object to become an element of a doubly linked list, the class of which

    16 that object is an instance, must include a <i>link</i> as a component.</p>

    17 <p>A link object has data members containing pointers which point forwards

    18 to the next link object and backwards to the previous link object. A link

    19 object also has function members to implement the behaviour expected of link

    20 objects, for example, connecting itself to another link object.</p>

    21 <p>A link is an instance of the <codeph>TDblQueLink</codeph> class.</p>
