Subscription

trait Subscription extends reactivestreams.Subscription

A Subscription represents a one-to-one lifecycle of a Observer subscribing to an Observable.

Instances can only be used once by a single Observer.

It is used to both signal desire for data and to allow for unsubscribing.

Abstract Value Members

  1. abstract def isUnsubscribed: Boolean

    Indicates whether this Subscription is currently unsubscribed.

    Indicates whether this Subscription is currently unsubscribed.

    returns

    true if this Subscription is currently unsubscribed, false otherwise

  2. abstract def request(n: Long): Unit

    No operation will be sent to MongoDB from the Observable until demand is signaled via this method.

    No operation will be sent to MongoDB from the Observable until demand is signaled via this method.

    It can be called however often and whenever needed, but the outstanding cumulative demand must never exceed Long.MaxValue. An outstanding cumulative demand of Long.MaxValue may be treated by the Observable as "effectively unbounded".

    Whatever has been requested might be sent, so only signal demand for what can be safely handled.

    An Observable can send less than is requested if the stream ends but then must emit either Observer.onError or Observer.onComplete.

    n

    the strictly positive number of elements to requests to the upstream Observable

  3. abstract def unsubscribe(): Unit

    Request the Observable to stop sending data and clean up resources.

    Request the Observable to stop sending data and clean up resources.

    As this request is asynchronous data may still be sent to meet previously signalled demand after calling cancel.

Concrete Value Members

  1. def cancel(): Unit

    Request the Observable to stop sending data and clean up resources.

    Request the Observable to stop sending data and clean up resources.

    As this request is asynchronous data may still be sent to meet previously signalled demand after calling cancel.
