@Beta
public interface ICompletableFuture<V>
extends Future<V>

A Future where one can asynchronously listen on completion. This functionality is needed for the reactive programming model. For more information see: http://download.java.net/jdk8/docs/api/java/util/concurrent/CompletableFuture.html This class can be dropped once Hazelcast relies on Java8+. It is added to make Hazelcast compatible with Java6/7.

Since:

3.2
