These methods request the PersistenceManager to load all persistent fields into
the parameter instances. Subsequent to this call, the application might
call makeTransient on the parameter instances, and the fields can no
longer be touched by the PersistenceManager. The PersistenceManager
might also retrieve related instances according to a pre-read policy
(not specified by JDO).
The JDO PersistenceManager loads persistent values from the datastore into the instance
and if the class of the instance implements InstanceCallbacks calls jdoPostLoad.
