Examples of org.apache.cayenne.access.ToManyList

org.apache.cayenne.access.ToManyList
A list that holds objects for to-many relationships. All operations, except for resolving the list from DB, are not synchronized. The safest way to implement custom synchronization is to synchronize on parent ObjectStore. @author Andrus Adamchik

        p1.setPaintingTitle("p1");
        artist.addToPaintingArray(p1);

        assertTrue("List must be unresolved...", list.isFault());


        Painting p2 = context.newObject(Painting.class);


        artist.addToPaintingArray(p2);

        context.rollbackChanges();


        assertTrue("List must be unresolved...", list.isFault());
