<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>
 <li><a href="../../../com/sleepycat/collections/StoredIterator.html#count()"><code>count()</code></a></li>
 <li><a href="../../../com/sleepycat/collections/StoredIterator.html#getCollection()"><code>getCollection()</code></a></li>
 <li><a href="../../../com/sleepycat/collections/StoredIterator.html#setReadModifyWrite(boolean)"><code>setReadModifyWrite(boolean)</code></a></li>

<div class="block">Inserts the specified element into the list or inserts a duplicate into
 other types of collections (optional operation).
 This method conforms to the <code>ListIterator.add(E)</code> interface when
 the collection is a list and the RECNO-RENUMBER access method is used.
 Otherwise, this method may only be called when duplicates are allowed.
 If duplicates are unsorted, the new value will be inserted in the same
 manner as list elements.
 If duplicates are sorted, the new value will be inserted in sort order.

 <p>Note that for the JE product, RECNO-RENUMBER databases are not
 supported, and therefore this method may only be used to add
 duplicates.</p></div>
