Method Detail

subscribeActual

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

Description copied from class: Maybe

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 Maybe.subscribe(MaybeObserver) before this method gets called.

Specified by:

subscribeActual in class Maybe<T>

Parameters:

observer - the MaybeObserver to handle, not null

onSubscribe

public void onSubscribe(Disposable d)

Description copied from interface: MaybeObserver

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.

Specified by:

onSubscribe in interface MaybeObserver<T>

Parameters:

d - the Disposable instance whose Disposable.dispose() can be called anytime to cancel the connection

onSuccess

public void onSuccess(T value)

Description copied from interface: MaybeObserver

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 MaybeObserver.onError(java.lang.Throwable).

Specified by:

onSuccess in interface MaybeObserver<T>

Parameters:

value - the item emitted by the Maybe

onError

public void onError(java.lang.Throwable e)

Description copied from interface: MaybeObserver

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

If the Maybe calls this method, it will not thereafter call MaybeObserver.onSuccess(T).

Specified by:

onError in interface MaybeObserver<T>

Parameters:

e - the exception encountered by the Maybe

onComplete

public void onComplete()

Description copied from interface: MaybeObserver

Called once the deferred computation completes normally.

Specified by:

onComplete in interface MaybeObserver<T>

add

boolean add(MaybeCache.CacheDisposable<T> inner)

remove

void remove(MaybeCache.CacheDisposable<T> inner)
