Methods

ToProperty<TObj, TRet>(IObservable<TRet>, TObj, Expression<Func<TObj, TRet>>, out ObservableAsPropertyHelper<TRet>, bool, IScheduler?)

Converts an Observable to an ObservableAsPropertyHelper and automatically provides the onChanged method to raise the property changed notification.

public static ObservableAsPropertyHelper<TRet> ToProperty<TObj, TRet>(this IObservable<TRet> target, TObj source, Expression<Func<TObj, TRet>> property, out ObservableAsPropertyHelper<TRet> result, bool deferSubscription = false, IScheduler? scheduler = null) where TObj : class, IReactiveObject

Parameters

target IObservable<TRet>

The observable to convert to an ObservableAsPropertyHelper.

source TObj

The ReactiveObject that has the property.

property Expression<Func<TObj, TRet>>

An Expression representing the property (i.e. x => x.SomeProperty).

result ObservableAsPropertyHelper<TRet>

An out param matching the return value, provided for convenience.

deferSubscription bool

A value indicating whether the ObservableAsPropertyHelper<T> should defer the subscription to the target source until the first call to Value, or if it should immediately subscribe to the target source.

scheduler IScheduler

The scheduler that the notifications will be provided on - this should normally be a Dispatcher-based scheduler.

Returns

ObservableAsPropertyHelper<TRet>

An initialized ObservableAsPropertyHelper; use this as the backing field for your property.

Type Parameters

TObj

The object type.

TRet

The result type.
