/**

 * <B>Keywords:</B> cache <br>
 * <B>Assertion ID:</B> A12.5.1-6. <br>
 * <B>Assertion Description: </B> The <code>PersistenceManager.refreshAll</code> method with no
 * parameters causes all transactional instances to be refreshed. Note that this method will cause
 * loss of changes made to affected instances by the application due to refreshing the contents from
 * the data store. The JDO <code>PersistenceManager</code>:
 *
 * <UL>
 *   <LI>loads persistent values from the data store;
 *   <LI>loads persistent fields into the instance;
 *   <LI>calls the <code>jdoPostLoad</code> method on each persistent instance, if the class of the
 *       instance implements <code>InstanceCallbacks</code>; and
 *   <LI>changes the state of persistent-dirty instances to persistent-clean.
 * </UL>
