public DelegateWitness(Action<T> onNext, Action<Exception>? onError = null, Action? onCompleted = null)
Summary:
A lightweight IObserver that forwards each notification to the supplied delegates.
Use it to subscribe to an IObservable without allocating a bespoke observer class.
The onError and onCompleted delegates are optional; when omitted
the corresponding terminal notification is ignored.
Parameters
| Name | Type | Description |
|---|---|---|
onNext | Action | The delegate invoked with each value pushed to OnNext. |
onError = null | Action | The optional delegate invoked with the exception when the sequence faults via OnError. |
onCompleted = null | Action? | The optional delegate invoked when the sequence finishes via OnCompleted. |
