Method Detail

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);
-
isUnsubscribed
public boolean isUnsubscribed()
Description copied from interface:Subscription
Indicates whether thisSubscription
is currently unsubscribed.- Specified by:
isUnsubscribed
in interfaceSubscription
- Returns:
true
if thisSubscription
is currently unsubscribed,false
otherwise
-
unsubscribe
public void unsubscribe()
Description copied from interface:Subscription
Stops the receipt of notifications on theSubscriber
that was registered when this Subscription was received.This allows unregistering an
Subscriber
before it has finished receiving all events (i.e. before onCompleted is called).- Specified by:
