Example usage for com.google.common.util.concurrent Futures addCallback

Introduction

In this page you can find the example usage for com.google.common.util.concurrent Futures addCallback.

Prototype

public static <V> void addCallback(ListenableFuture<V> future, FutureCallback<? super V> callback) 

Source Link

Document

Registers separate success and failure callbacks to be run when the Future 's computation is java.util.concurrent.Future#isDone() complete or, if the computation is already complete, immediately.

Usage

From source file:io.crate.executor.transport.task.UpdateTask.java
