Method Details

subscribeActual

protected void subscribeActual(CompletableObserver observer)

Description copied from class: Completable

Implement this method to handle the incoming CompletableObservers and perform the business logic in your operator.

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

Specified by:

subscribeActual in class Completable

Parameters:

observer - the CompletableObserver instance, never null

onSubscribe

public void onSubscribe(Disposable d)

Description copied from interface: CompletableObserver

Called once by the Completable to set a Disposable on this instance which then can be used to cancel the subscription at any time.

Specified by:

onSubscribe in interface CompletableObserver

Parameters:

d - the Disposable instance to call dispose on for cancellation, not null

onError

public void onError(Throwable e)

Description copied from interface: CompletableObserver

Called once if the deferred computation 'throws' an exception.

Specified by:

onError in interface CompletableObserver

Parameters:

e - the exception, not null.

onComplete

public void onComplete()

Description copied from interface: CompletableObserver

Called once the deferred computation completes normally.

Specified by:

onComplete in interface CompletableObserver

add

boolean add(CompletableCache.InnerCompletableCache inner)

remove

void remove(CompletableCache.InnerCompletableCache inner)
