<div class="block">The Iterator returned by all stored collections.
<p>While in general this class conforms to the <code>Iterator</code> interface,
it is important to note that all iterators for stored collections must be
explicitly closed with <a href="../../../com/sleepycat/collections/StoredIterator.html#close--"><code>close()</code></a>. The static method <a href="../../../com/sleepycat/collections/StoredIterator.html#close-java.util.Iterator-"><code>close(java.util.Iterator)</code></a> allows calling close for all iterators without
harm to iterators that are not from stored collections, and also avoids
casting. If a stored iterator is not closed, unpredictable behavior
including process death may result.</p>
<p>This class implements the <code>Iterator</code> interface for all stored
iterators. It also implements <code>ListIterator</code> because some list
iterator methods apply to all stored iterators, for example, <a href="../../../com/sleepycat/collections/StoredIterator.html#previous--"><code>previous()</code></a> and <a href="../../../com/sleepycat/collections/StoredIterator.html#hasPrevious--"><code>hasPrevious()</code></a>. Other list iterator methods are always
supported for lists, but for other types of collections are only supported
under certain conditions. See <a href="../../../com/sleepycat/collections/StoredIterator.html#nextIndex--"><code>nextIndex()</code></a>, <a href="../../../com/sleepycat/collections/StoredIterator.html#previousIndex--"><code>previousIndex()</code></a>,
<a href="../../../com/sleepycat/collections/StoredIterator.html#add-E-"><code>add(E)</code></a> and <a href="../../../com/sleepycat/collections/StoredIterator.html#set-E-"><code>set(E)</code></a> for details.</p>
<p>In addition, this class provides the following methods for stored
collection iterators only. Note that the use of these methods is not
compatible with the standard Java collections interface.</p>
<ul>
<li><a href="../../../com/sleepycat/collections/StoredIterator.html#close--"><code>close()</code></a></li>
<li><a href="../../../com/sleepycat/collections/StoredIterator.html#close-java.util.Iterator-"><code>close(Iterator)</code></a></li>
