Method Detail

isDisposed

public boolean isDisposed()

Description copied from interface: Disposable

Returns true if this resource has been disposed.

Specified by:

isDisposed in interface Disposable

Returns:

true if this resource has been disposed

dispose

public void dispose()

Description copied from interface: Disposable

Dispose the resource, the operation should be idempotent.

Specified by:

dispose in interface Disposable

add

boolean add(FlowableReplay.InnerSubscription<T> producer)

Atomically try adding a new InnerSubscription to this Subscriber or return false if this Subscriber was terminated.

Parameters:

producer - the producer to add

Returns:

true if succeeded, false otherwise

remove

void remove(FlowableReplay.InnerSubscription<T> p)

Atomically removes the given InnerSubscription from the subscribers array.

Parameters:

p - the InnerSubscription to remove

onSubscribe

public void onSubscribe(org.reactivestreams.Subscription p)

Description copied from interface: FlowableSubscriber

Implementors of this method should make sure everything that needs to be visible in Subscriber.onNext(Object) is established before calling Subscription.request(long). In practice this means no initialization should happen after the request() call and additional behavior is thread safe in respect to onNext.

Specified by:

onSubscribe in interface FlowableSubscriber<T>

Specified by:

onSubscribe in interface org.reactivestreams.Subscriber<T>

onNext

public void onNext(T t)

Specified by:

onNext in interface org.reactivestreams.Subscriber<T>

onError

public void onError(java.lang.Throwable e)

Specified by:

onError in interface org.reactivestreams.Subscriber<T>

onComplete

public void onComplete()

Specified by:

onComplete in interface org.reactivestreams.Subscriber<T>

manageRequests

void manageRequests()

Coordinates the request amounts of various child Subscribers.
