request
public void request(long n) Description copied from interface:Producer
Request a certain maximum number of items from this Producer. This is a way of requesting backpressure. To disable backpressure, passLong.MAX_VALUE
to this method.Requests are additive but if a sequence of requests totals more than
Long.MAX_VALUE
thenLong.MAX_VALUE
requests will be actioned and the extras may be ignored. Arriving atLong.MAX_VALUE
by addition of requests cannot be assumed to disable backpressure. For example, the code below may result inLong.MAX_VALUE
requests being actioned only.request(100); request(Long.MAX_VALUE-1);
