Method Summary

Modifier and Type	Method and Description
void	complete()
void	error(java.lang.Throwable e)
boolean	isCancelled() Returns true if the downstream cancelled the sequence.
void	next(T t) Try emitting, might throw an unchecked exception.
long	requestedFromDownstream() The current outstanding request amount.
FluxSink<T>	serialize() Ensures that calls to next, error and complete are properly serialized.
void	setCancellation(Cancellation c) Associate a cancellation-based resource with this FluxSink that will be disposed in case the downstream cancels the sequence via Subscription.cancel().
