<DT><PRE>public class <B>StoredIterator</B><DT>extends java.lang.Object<DT>implements java.lang.Cloneable</DL>
</PRE>
<P>
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(java.lang.Object)"><CODE>add(java.lang.Object)</CODE></A> and <A HREF="../../../com/sleepycat/collections/StoredIterator.html#set(java.lang.Object)"><CODE>set(java.lang.Object)</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>

<li><A HREF="../../../com/sleepycat/collections/StoredIterator.html#close()"><CODE>close()</CODE></A></li>

<DL>
<DD>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>

<DT><B>Throws:</B>
<DD><CODE>java.lang.UnsupportedOperationException</CODE> - if the collection is a sublist, or
if the collection is indexed, or if the collection is read-only, or if
the collection is a list and the RECNO-RENUMBER access method was not
used, or if the collection is not a list and duplicates are not allowed.
<DD><CODE>java.lang.IllegalStateException</CODE> - if the collection is empty and is not a
list with RECNO-RENUMBER access.
<DD><CODE>java.lang.IllegalArgumentException</CODE> - if a duplicate value is being added
that already exists and duplicates are sorted.
