<P>
The Set returned by Map.entrySet(). This class may not be instantiated
directly. Contrary to what is stated by <A HREF="http://java.sun.com/j2se/1.3/docs/api/java/util/Map.html#entrySet()" title="class or interface in java.util"><CODE>Map.entrySet()</CODE></A> this class
does support the <A HREF="../../../com/sleepycat/collections/StoredEntrySet.html#add(java.lang.Object)"><CODE>add(java.lang.Object)</CODE></A> and <A HREF="../../../com/sleepycat/collections/StoredCollection.html#addAll(java.util.Collection)"><CODE>StoredCollection.addAll(java.util.Collection)</CODE></A> methods.
<p>The <A HREF="http://java.sun.com/j2se/1.3/docs/api/java/util/Map.Entry.html#setValue(java.lang.Object)" title="class or interface in java.util"><CODE>Map.Entry.setValue(java.lang.Object)</CODE></A> method of the Map.Entry objects
that are returned by this class and its iterators behaves just as the <A HREF="../../../com/sleepycat/collections/StoredIterator.html#set(java.lang.Object)"><CODE>StoredIterator.set(java.lang.Object)</CODE></A> method does.</p>
<p><em>Note that this class does not conform to the standard Java
collections interface in the following ways:</em></p>
<ul>
<li>The <A HREF="../../../com/sleepycat/collections/StoredContainer.html#size()"><CODE>StoredContainer.size()</CODE></A> method always throws
<code>UnsupportedOperationException</code> because, for performance reasons,
databases do not maintain their total record count.</li>
<li>All iterators must be explicitly closed using <A HREF="../../../com/sleepycat/collections/StoredIterator.html#close()"><CODE>StoredIterator.close()</CODE></A> or <A HREF="../../../com/sleepycat/collections/StoredIterator.html#close(java.util.Iterator)"><CODE>StoredIterator.close(java.util.Iterator)</CODE></A>
to release the underlying database cursor resources.</li>
