Subscription (original) (raw)

@Deprecated
public interface 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.

• • Method Detail

     * #### request  
     void request​(long n)  
     Deprecated.  
     No operation will be sent to MongoDB from the [Observable](Observable.html "interface in com.mongodb.async.client") 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.MAX_VALUE`. An outstanding cumulative demand of `Long.MAX_VALUE` may be treated by the [Observable](Observable.html "interface in com.mongodb.async.client") as "effectively unbounded".  
      Whatever has been requested might be sent, so only signal demand for what can be safely handled.  
      An [Observable](Observable.html "interface in com.mongodb.async.client") can send less than is requested if the stream ends but then must emit either[Observer.onError(Throwable)](Observer.html#onError%28java.lang.Throwable%29) or [Observer.onComplete()](Observer.html#onComplete%28%29).  
     Parameters:  
     `n` \- the strictly positive number of elements to requests to the upstream [Observable](Observable.html "interface in com.mongodb.async.client")  
     * #### unsubscribe  
     void unsubscribe()  
     Deprecated.  
     Request the [Observable](Observable.html "interface in com.mongodb.async.client") 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.  
     * #### isUnsubscribed  
     boolean isUnsubscribed()  
     Deprecated.  
     Indicates whether this `Subscription` is currently unsubscribed.  
     Returns:  
     `true` if this `Subscription` is currently unsubscribed, `false` otherwise
