Class ConservativeClientFuture<V>

java.lang.Object

org.apache.qpid.protonj2.client.futures.ClientFuture<V>

org.apache.qpid.protonj2.client.futures.ConservativeClientFuture<V>

Type Parameters:

V - The type that result from completion of this Future

All Implemented Interfaces:

java.util.concurrent.Future<V>, AsyncResult<V>

public class ConservativeClientFuture<V>
extends ClientFuture<V>

A more conservative implementation of a ClientFuture that is better on some platforms or resource constrained hardware where high CPU usage can be more counter productive than other variants that might spin or otherwise avoid entry into states requiring thread signaling.
