Examples of javax.jdo.Query.closeAll()

javax.jdo.Query.closeAll()
Close all query results associated with this Query instance, and release all resources associated with them. The query results might have iterators open on them. Iterators associated with the query results are invalidated: they return false to hasNext() and throw NoSuchElementException to next().

        while(it.hasNext()) {
            Address a = (Address) it.next();
            System.out.println("Address (" + a + ")");
            i++;
        }
        q.closeAll();
        System.out.println("There is " + i + " addresses.");


        q = pm.newQuery(Invoice.class);
        col = (Collection) q.execute();
        it = col.iterator();
