Implements abstract io.reactivex.Observable.subscribeActual.

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

public void subscribeActual(Observer<? super T> t)

Implements abstract io.reactivex.Observable.subscribeActual.

Doc from io.reactivex.Observable.subscribeActual.

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

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

Parameters
t:Observer<? super T>

the incoming Observer, never null

Implements io.reactivex.Observer.onSubscribe.

Provides the Observer with the means of cancelling (disposing) the connection (channel) with the Observable in both synchronous (from within onNext(Object)) and asynchronous manner.

onCompleteback to summary
public void onComplete()

Implements io.reactivex.Observer.onComplete.

public void onError(Throwable t)

Implements io.reactivex.Observer.onError.

Doc from io.reactivex.Observer.onError.

Notifies the Observer that the Observable has experienced an error condition.

If the Observable calls this method, it will not thereafter call onNext or onComplete.

Parameters
t:Throwable

the exception encountered by the Observable

public void onNext(T t)

Implements io.reactivex.Observer.onNext.

Doc from io.reactivex.Observer.onNext.

Provides the Observer with a new item to observe.

The Observable may call this method 0 or more times.

The Observable will not call this method again after it calls either onComplete or onError.

Parameters
t:T

the item emitted by the Observable
