Package io.reactivex.rxjava3.observers
Class DisposableCompletableObserver
- java.lang.Object

- io.reactivex.rxjava3.observers.DisposableCompletableObserver
-
- All Implemented Interfaces:
CompletableObserver
,Disposable
public abstract class DisposableCompletableObserver extends java.lang.Object implements CompletableObserver, Disposable
An abstractCompletableObserver
that allows asynchronous cancellation by implementing Disposable.All pre-implemented final methods are thread-safe.
Like all other consumers,
DisposableCompletableObserver
can be subscribed only once. Any subsequent attempt to subscribe it to a new source will yield anIllegalStateException
with message"It is not allowed to subscribe with a(n) <class name> multiple times."
.Implementation of
onStart()
,CompletableObserver.onError(Throwable)
andCompletableObserver.onComplete()
are not allowed to throw any unchecked exceptions.Example
Disposable d = Completable.complete().delay(1, TimeUnit.SECONDS) .subscribeWith(new DisposableMaybeObserver<Integer>() { @Override public void onStart() { System.out.println("Start!"); } @Override public void onError(Throwable t) { t.printStackTrace(); } @Override public void onComplete() { System.out.println("Done!"); } }); // ... d.dispose();
