Guarded by connection (not this).

EMPTY

static final CachedObservable.ReplayProducer<?>[] EMPTY

The default empty array of producers.

nl

final NotificationLite<T> nl

Constructor Detail

CacheState

public CacheState(Observable<? extends T> source,
                  int capacityHint)

Method Detail

addProducer

public void addProducer(CachedObservable.ReplayProducer<T> p)

Adds a ReplayProducer to the producers array atomically.

Parameters:

p -

removeProducer

public void removeProducer(CachedObservable.ReplayProducer<T> p)

Removes the ReplayProducer (if present) from the producers array atomically.

Parameters:

p -

connect

public void connect()

Connects the cache to the source. Make sure this is called only once.

onNext

public void onNext(T t)

Description copied from interface: Observer

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 Observer.onCompleted() or Observer.onError(java.lang.Throwable).

Specified by:

onNext in interface Observer<T>

Parameters:

t - the item emitted by the Observable

onError

public void onError(java.lang.Throwable e)

Description copied from interface: Observer

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

If the Observable calls this method, it will not thereafter call Observer.onNext(T) or Observer.onCompleted().

Specified by:

onError in interface Observer<T>

Parameters:

e - the exception encountered by the Observable

onCompleted

public void onCompleted()

Description copied from interface: Observer

Notifies the Observer that the Observable has finished sending push-based notifications.

The Observable will not call this method if it calls Observer.onError(java.lang.Throwable).

Specified by:

onCompleted in interface Observer<T>

dispatch

void dispatch()

Signals all known children there is work to do.
