4 * The ODMG List collection.
5 * A <code>DList</code> collection is an ordered collection that provides
6 * efficient insertion and removal of elements at arbitrary positions in the
7 * list, but it also supports indexed access. The beginning index value is 0.
8 * When an element is added at a given position in the list, the index of all
9 * subsequent elements is increased by 1. Similarly, when an element is removed
10 * from the list, the index of all subsequent elements is decreased by 1.
11 * <p>
12 * All of the operations defined by the JavaSoft <code>List</code>
13 * interface are supported by an ODMG implementation of <code>DList</code>,
14 * the exception <code>UnsupportedOperationException</code> is not thrown when a
15 * call is made to any of the <code>List</code> methods.
