|

A concrete <code>EntryBinding</code> that treats a key or data entry as
|
|
a serialized object.
|
|
|
|
<p>This binding stores objects in serialized object format. The
|
|
deserialized objects are returned by the binding, and their
|
|
<code>Class</code> must implement the <code>Serializable</code>
|
|
interface.</p>
|
|
|
|
<p>For key bindings, a tuple binding is usually a better choice than a
|
|
serial binding. A tuple binding gives a reasonable sort order, and works
|
|
with comparators in all cases -- see below.</p>
|
|
|
|
<p><em>WARNING:</em> SerialBinding should not be used with Berkeley DB Java
|
|
Edition for key bindings, when a custom comparator is used. In JE,
|
|
comparators are instantiated and called internally at times when databases
|
|
are not accessible. Because serial bindings depend on the class catalog
|
|
database, a serial binding cannot be used during these times. An attempt
|
|
to use a serial binding with a custom comparator will result in a
|
|
NullPointerException during environment open or close.</p>
