<p>This class is the reverse class adaptor for all dbstl iterator classes. </p>
|
||
<p>It inherits from real iterator classes like <a class="link" href="db_vector_iterator.html" title="Chapter 13. Db_vector_iterator">db_vector_iterator</a>
|
||
, <a class="link" href="db_map_iterator.html" title="Chapter 16. Db_map_iterator">db_map_iterator</a>
|
||
or <a class="link" href="db_set_iterator.html" title="Chapter 19. Db_set_iterator">db_set_iterator</a>
|
||
. When you call container::rbegin(), you will get an instance of this class. </p>

<p>When we talk about reverse iterator movement, we think the container is a uni-directional range, represented by [begin, end), and this is true no matter we are using iterators or reverse iterators.</p>
|
||
<p>When an iterator is moved closer to "begin", we say it is moved forward, otherwise we say it is moved backward. </p>
