public MaybeSource<T> source()

Implements io.reactivex.internal.fuseable.HasUpstreamMaybeSource.source.

Doc from io.reactivex.internal.fuseable.HasUpstreamMaybeSource.source.

Returns the upstream source of this Maybe.

Allows discovering the chain of observables.

Returns:MaybeSource<T>

protected void subscribeActual(SingleObserver<? super Boolean> observer)

Implements abstract io.reactivex.Single.subscribeActual.

Doc from io.reactivex.Single.subscribeActual.

Implement this method in subclasses to handle the incoming SingleObservers.

There is no need to call any of the plugin hooks on the current Single instance or the SingleObserver; all hooks and basic safeguards have been applied by subscribe(SingleObserver) before this method gets called.

Parameters
observer:SingleObserver<? super Boolean>

the SingleObserver to handle, not null

Method Summary

Modifier and TypeMethod and Description
public void
dispose()

Implements io.reactivex.disposables.Disposable.dispose.

Dispose the resource, the operation should be idempotent.
public boolean
isDisposed()

Implements io.reactivex.disposables.Disposable.isDisposed.

Returns true if this resource has been disposed.
public void
onComplete()

Implements io.reactivex.MaybeObserver.onComplete.

Called once the deferred computation completes normally.
public void
onError(Throwable

e)

Implements io.reactivex.MaybeObserver.onError.

Notifies the MaybeObserver that the Maybe has experienced an error condition.
public void
onSubscribe(Disposable
the Disposable instance whose Disposable#dispose() can be called anytime to cancel the connection
d)

Implements io.reactivex.MaybeObserver.onSubscribe.

Provides the MaybeObserver with the means of cancelling (disposing) the connection (channel) with the Maybe in both synchronous (from within onSubscribe(Disposable) itself) and asynchronous manner.
public void
onSuccess(Object
the item emitted by the Maybe
value)

Implements io.reactivex.MaybeObserver.onSuccess.

Notifies the MaybeObserver with one item and that the Maybe has finished sending push-based notifications.
