ObservableAsPropertyHelper<T> Class

Summary

ObservableAsPropertyHelper is a class to help ViewModels implement "output properties", that is, a property that is backed by an Observable. The property will be read-only, but will still fire change notifications. This class can be created directly, but is more often created via the OAPHCreationHelperMixin extension methods.

    IEnableLogger

Type Parameters

Name Description
T The type.

Constructors

Properties

Name Value Summary
IsSubscribed bool
Gets a value indicating whether the ObservableAsPropertyHelper has subscribed to the source Observable. Useful for scenarios where you use deferred subscription and want to know if the ObservableAsPropertyHelper Value has been accessed yet.
ThrownExceptions IObservable<Exception>
Gets an observable which signals whenever an exception would normally terminate ReactiveUI internal state.
Value T
Gets the last provided value from the Observable.

Methods

Name Value Summary
Default(T?, IScheduler?) ObservableAsPropertyHelper<T>
Constructs a "default" ObservableAsPropertyHelper object. This is useful for when you will initialize the OAPH later, but don't want bindings to access a null OAPH at startup.
static
Dispose() void
Disposes this ObservableAsPropertyHelper.
