Guaranteed idempotency - calling it multiple times should have the same side-effect as calling it only once. Implementations of this method should also be thread-safe.
No events will be sent by a Publisher until demand is
signaled via this method.
No events will be sent by a Publisher until demand is
signaled via this method.
It can be called however often and whenever needed.
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 onError or onComplete.
The Subscriber MAY call this method synchronously in the implementation of its
onSubscribe / onNext methods, therefore the effects of this function must be
asynchronous, otherwise it could lead to a stack overflow.
signals demand for the number of onNext events that the Subscriber wants,
if positive, then the Publisher is bound by contract to not send more than
this number of onNext events and if negative, then this signals to the
Publisher that it may send an infinite number of events, until the subscription
gets cancelled or the stream is complete.
The
Subscriptionrepresents a cross between the Monix Cancelable andorg.reactivestreams.Subcription.Represents a one-to-one lifecycle of a
Subscribersubscribing to aPublisherand mirrors theSubscriptioninterface from the Reactive Streams specification.It can be used only once by a single
Subscriber. It is used for both signaling demand for data and for canceling demand (and allow resource cleanup).
