public abstract class DisposableCompletableObserver extends Object implements CompletableObserver, Disposable
CompletableObserver
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 an
IllegalStateException
with message "It is not allowed to subscribe with a(n) <class name> multiple times."
.
Implementation of onStart()
, CompletableObserver.onError(Throwable)
and
CompletableObserver.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();
