There is one further possibility. The <literal>Interceptor</literal> method named
<literal>isUnsaved()</literal> lets the application implement its own strategy for distinguishing
newly instantiated objects. For example, you could define a base class for your persistent classes.
</para>
<programlisting><![CDATA[public class Persistent {
private boolean _saved = false;
public void onSave() {
_saved=true;
}
public void onLoad() {
_saved=true;
}
......
public boolean isSaved() {
return _saved;
}
}]]></programlisting>
<para>
(The <literal>saved</literal> property is non-persistent.)
Now implement <literal>isUnsaved()</literal>, along with <literal>onLoad()</literal>
and <literal>onSave()</literal> as follows.
</para>
<programlisting><![CDATA[public Boolean isUnsaved(Object entity) {
if (entity instanceof Persistent) {
return new Boolean( !( (Persistent) entity ).isSaved() );
}
else {
return null;
}
}
public boolean onLoad(Object entity,
Serializable id,
Object[] state,
String[] propertyNames,
Type[] types) {
if (entity instanceof Persistent) ( (Persistent) entity ).onLoad();
return false;
}
public boolean onSave(Object entity,
Serializable id,
Object[] state,
String[] propertyNames,
Type[] types) {
if (entity instanceof Persistent) ( (Persistent) entity ).onSave();
return false;
}]]></programlisting>

Don't worry; in Hibernate3 you don't need to write any of this kind of code if you don't want to.
