dematerialize<S> method
Converts the onData, onDone, and onError Notification objects from a materialized stream into normal onData, onDone, and onError events.
When a stream has been materialized, it emits onData, onDone, and onError events as Notification objects. Dematerialize simply reverses this by transforming Notification objects back to a normal stream of events.
Example
new Observable<Notification<int>>
.fromIterable([new Notification.onData(1), new Notification.onDone()])
.dematerialize()
.listen((i) => print(i)); // Prints 1
Error example
new Observable<Notification<int>>
.just(new Notification.onError(new Exception(), null))
.dematerialize()
.listen(null, onError: (e, s) { print(e) }); // Prints Exception
Implementation
Observable<S> dematerialize<S>() {
return cast<Notification<S>>()
.transform(DematerializeStreamTransformer<S>());
}
