<DD>Configures the entry with an application-owned buffer.
<p>
The <code>data</code> field of the entry must refer to a buffer that is
at least <code>length</code> bytes in length.
<p>
If the length of the requested item is less than or equal to that number
of bytes, the item is copied into the memory to which the
<code>data</code> field refers. Otherwise, the <code>size</code> field
is set to the length needed for the requested item, and a
<A HREF="../../../com/sleepycat/db/MemoryException.html" title="class in com.sleepycat.db"><CODE>MemoryException</CODE></A> is thrown.
<p>
Applications can determine the length of a record by setting
<code>length</code> to 0 and calling <A HREF="../../../com/sleepycat/db/DatabaseEntry.html#getSize()"><CODE>DatabaseEntry.getSize</CODE></A>
on the return value.
