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: https://docs.oracle.com/javase/8/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

Method Detail

andThen

void andThen(ExecutionCallback<V> callback)

Registers a callback that will run after this future is completed. If this future is already completed, it runs immediately.

Please note that there is no ordering guarantee for running multiple callbacks. It is also not guaranteed that the callback will run within the same thread that completes the future.

Parameters:

callback - the callback to execute

andThen

void andThen(ExecutionCallback<V> callback,
             Executor executor)

Registers a callback that will run with the provided executor after this future is completed. If this future is already completed, it runs immediately. The callback is called using the given executor. Please note that there is no ordering guarantee for executing multiple callbacks.

Parameters:

callback - the callback to execute

executor - the executor in which the callback will be run
