If PersistenceManager.evict is called with no parameter, then all referenced instances are evicted. For each instance evicted, it:
*<UL>
*<LI> calls the jdoPreClearmethod on each instance, if the class of the instance implements InstanceCallbacks </LI>
*<LI> clears persistent fields on each instance after the call to jdoPreClear()</LI>
*<LI> changes the state of instances to hollow or persistent-nontransactional (cannot distinguish between these two states) this is not directly testable. </LI>
*</UL>
