NotifyField
UIViewModel과 연동하여 동작 하도록 설계되었으며 각Field의 값이 변경되면View에NotifyFieldChangedEventArgs를 발행하여 특정Field가 변경돈 사실을 고지UIViewModel내의NotifyField는UIViewModel이 생성될 때 자동 연동 되며 필요시Event를 추가로 등록할 수 있음
public delegate void NotifyFieldChangedHandler(NotifyFieldChangedEventArgs args);
public class NotifyFieldChangedEventArgs : EventArgs {
public new static NotifyFieldChangedEventArgs Empty { get; } = new();
}
public class NotifyCollectionChangedEventArgs : NotifyFieldChangedEventArgs {
public readonly NotifyCollectionChangedAction action;
public NotifyCollectionChangedEventArgs(NotifyCollectionChangedAction action) => this.action = action;
}
- NotifyProperty
일반 적인
Field대한 반응형Property
참조 타입의 경우
IEqualityComparer<TValue>구현 필요
NotifyCollection
열거형
(IEnumerable)을 구현하는 타입에 대한 통합 추상 클래스NotifyProperty와는 다르게Event를 통해 추가로 어떤 타입의Action이 발생하였는지 알릴 필요성이 있음
- NotifyCollection(TCollection, TValue)
Collection,NotifyList,NotifyDictionary에 기본 상속되며 열거형(IEnumerable)을 구현하는 타입에 대한 기초 추상화를 제공
- NotifyCollection(TValue)
Collection구조에 대한 반응형Property
- NotifyList
List구조에 대한 반응형Property
- NotifyDictionary
Dictionary구조에 대한 반응형Property
public class SampleUIViewModel : UIViewModel {
public readonly NotifyProperty<int> Count = new();
public void IncreaseCount(int count) => Count.Value += count;
public void DecreaseCount(int count) => Count.Value -= count;
}
public class SampleUIView : UIView<SampleUIViewModel> {
public void OnIncreaseInteraction(int count) => viewModel.IncreaseCount(count);
public void OnDecreaseInteraction(int count) => viewModel.DecreaseCount(count);
}

}
public class SampleUIView : UIView<SampleUIViewModel> {
