Examples of org.apache.cayenne.ObjectContext.invalidateObjects()

org.apache.cayenne.ObjectContext.invalidateObjects()
Invalidates a Collection of persistent objects. This operation only applies to the objects already committed to the database and does nothing to the NEW objects. It would remove each object's snapshot from caches and change object's state to HOLLOW. On the next access to this object, the object will be refetched. @see RefreshQuery

        Artist childDeleted = (Artist) objects.get(2);
        childContext.deleteObjects(childDeleted);
        childDeleted.setArtistName("DDD");


        Artist childHollow = (Artist) objects.get(3);
        childContext.invalidateObjects(childHollow);


        childContext.commitChanges();


        assertEquals(PersistenceState.COMMITTED, childNew.getPersistenceState());
        assertEquals(PersistenceState.COMMITTED, childModified.getPersistenceState());
