request back to summary

public void request(long n)

Implements org.reactivestreams.Subscription.request.

Doc from org.reactivestreams.Subscription.request.

No events will be sent by a Publisher until demand is signaled via this method.

It can be called however often and whenever needed—but if the outstanding cumulative demand ever becomes Long.MAX_VALUE or more, it may be treated by the Publisher as "effectively unbounded".

Whatever has been requested can be sent by the Publisher so only signal demand for what can be safely handled.

A Publisher can send less than is requested if the stream ends but then must emit either Subscriber#onError(Throwable) or Subscriber#onComplete().

Parameters

n:long: the strictly positive number of elements to requests to the upstream Publisher
