Namespace: Semata.DataStore.ObjectModel.Views
A list ItemObjects that will be loaded from an ItemObjectCollection. The list will only be loaded when accessed, not when created, i.e. it is lazy
generic <typename I, typename V> where I : ItemObject where V : ItemObjectView<I> public ref class ItemObjectViewList : public IList<V^> , IList , IReadOnlyList<V^> , INotifyCollectionChanged , INotifyStateChanged , IEditableDataCreator
Implements: IList<V> , IList , IReadOnlyList<V> , INotifyCollectionChanged , INotifyStateChanged , IEditableDataCreator
Constructors
| Name | Description |
| ItemObjectViewList(ItemObjectCollection<I>^, Func<I, V>^) |
Constructs a new instance of ItemObjectViewList. |
| ItemObjectViewList(ItemObjectCollection<I>^, Func<IEnumerable<I>, IEnumerable<I>>^, Func<I, V>^) |
Constructs a new instance of ItemObjectViewList. |
| 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() |
