| ItemObjectViewList(ItemObjectCollection<I>, Func<IEnumerable<I>, IEnumerable<I>>, Func<I, V>, Action<V>, Action<V>, bool) |
Constructs a new instance of ItemObjectViewList. If delayRemoves is true, it would be usual to set WriteOnEndEdit to false on the ItemObjectView created by Creator(). So that both adds and removes are performed on WriteChanges() |
