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` Annotations @Override

Request a fusion mode from the upstream. This should be called before `onSubscribe` returns. Calling this method multiple times or after `onSubscribe` finished is not allowed and may result in undefined behavior. Parameters mode:int the requested fusion mode, allowed values are `SYNC`, `ASYNC`, `ANY` combined with `BOUNDARY` (e.g., `requestFusion(SYNC \| BOUNDARY)`). Returns:int the established fusion mode: `NONE`, `SYNC`, `ASYNC`. Annotations @Override
