protected void subscribeActual(MaybeObserver<? super R> observer)

Implements abstract io.reactivex.Maybe.subscribeActual.

Doc from io.reactivex.Maybe.subscribeActual.

Implement this method in subclasses to handle the incoming MaybeObservers.

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

Parameters
observer:MaybeObserver<? super R>

the MaybeObserver to handle, not null

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(T
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.
