Package org.apache.dubbo.rpc.protocol.dubbo

Class FutureAdapter<V>

java.lang.Object

java.util.concurrent.CompletableFuture<V>

org.apache.dubbo.rpc.protocol.dubbo.FutureAdapter<V>

All Implemented Interfaces:

CompletionStage<V>, Future<V>

public class FutureAdapter<V>
extends CompletableFuture<V>

This is the type of the Future instance users get in an async call: 1. unwrap AppResponse in appResponseFuture and convert to plain biz result represented by FutureAdapter. 2. customized behaviors meaningful for RPC, for example, cancel(boolean)
