postCompleteRequest

public static <T> boolean postCompleteRequest(long n,
                                              org.reactivestreams.Subscriber<? super T> downstream,
                                              Queue<T> queue,
                                              AtomicLong requested,
                                              BooleanSupplier isCancelled)

Perform a potential post-completion request accounting.

Type Parameters:

T - the output value type

Parameters:

n - the requested amount

downstream - the downstream consumer

queue - the queue holding the available values

requested - the requested atomic long

isCancelled - callback to detect cancellation
