subscribeActualback to summary
protected void subscribeActual(Subscriber<? super T> s)

Implements abstract io.reactivex.Flowable.subscribeActual.

Doc from io.reactivex.Flowable.subscribeActual.

Operator implementations (both source and intermediate) should implement this method that performs the necessary business logic and handles the incoming Subscribers.

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

Parameters
s:Subscriber<? super T>

the incoming Subscriber, never null

Implements io.reactivex.MaybeObserver.onComplete.

Called once the deferred computation completes normally.
public void
onError(Throwable
the exception encountered by the Maybe
e)

Implements io.reactivex.MaybeObserver.onError.

Notifies the MaybeObserver that the Maybe has experienced an error condition.
public void
onSubscribe(Disposable

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.
public void
request(long
the strictly positive number of elements to requests to the upstream Publisher
n)

Implements org.reactivestreams.Subscription.request.

No events will be sent by a Publisher until demand is signaled via this method.

public void cancel()

Implements org.reactivestreams.Subscription.cancel.

Request the Publisher to stop sending data and clean up resources.

Data may still be sent to meet previously signalled demand after calling cancel.

onErrorback to summary
public void onError(Throwable e)

Implements io.reactivex.MaybeObserver.onError.

Doc from io.reactivex.MaybeObserver.onError.

Notifies the MaybeObserver that the Maybe has experienced an error condition.

If the Maybe calls this method, it will not thereafter call onSuccess.

Parameters
e:Throwable

the exception encountered by the Maybe

Annotations
@Override
onSubscribeback to summary
public void onSubscribe(Disposable d)

Implements io.reactivex.MaybeObserver.onSubscribe.

Doc from 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.

Parameters
d:Disposable

the Disposable instance whose Disposable#dispose() can be called anytime to cancel the connection

Annotations
@Override
onSuccessback to summary
public void onSuccess(T value)

Implements io.reactivex.MaybeObserver.onSuccess.

Doc from io.reactivex.MaybeObserver.onSuccess.

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

The Maybe will not call this method if it calls onError.

Parameters
value:T

the item emitted by the Maybe

Annotations
@Override
requestback to summary
public void request(long n)

Implements org.reactivestreams.Subscription.request.

Doc from org.reactivestreams.Subscription.request.

No events will be sent by a Publisher until demand is signaled via this method.

It can be called however often and whenever needed—but if the outstanding cumulative demand ever becomes Long.MAX_VALUE or more, it may be treated by the Publisher as "effectively unbounded".

Whatever has been requested can be sent by the Publisher so only signal demand for what can be safely handled.

A Publisher can send less than is requested if the stream ends but then must emit either Subscriber#onError(Throwable) or Subscriber#onComplete().

Parameters
n:long

the strictly positive number of elements to requests to the upstream Publisher
