Namespace
NanoByte.Common.Dispatch
Assembly
NanoByte.Common.dll

Keeps two collections of different types in sync based on mapping rules.

[MustDisposeResource]
public sealed class ModelViewSync<TModel, TView> where TModel : class, IChangeNotify<TModel> where TView : class

Type Parameters

TModel

The common base type of elements in the model.

TView

The common base type of representations in the view.

Inheritance
object
ModelViewSync<TModel, TView>
Extension Methods

Remarks

Useful for maintaining View representations for a set of mutable Model elements in a Model-View-Controller/Presenter design. Generated View representations will automatically be disposed on removal, if they implement System.IDisposable.

Constructors

ModelViewSync(MonitoredCollection<TModel>, ICollection<TView>)

Keeps two collections of different types in sync based on mapping rules.

public ModelViewSync(MonitoredCollection<TModel> model, ICollection<TView> view)

Parameters

model MonitoredCollection<TModel>

The Model that can change on its own accord.

view ICollection<TView>

The View that is to be automatically updated to reflect changes in the Model.
