AppResponse (Apache Dubbo 2.7.14 API)

java.lang.Object
- org.apache.dubbo.rpc.AppResponse

所有已实现的接口:

Serializable, Result
```
public class AppResponse
extends Object
implements Result
```
AsyncRpcResult is introduced in 3.0.0 to replace RpcResult, and RpcResult is replaced with AppResponse:
- AsyncRpcResult is the object that is actually passed in the call chain
- AppResponse only simply represents the business result
The relationship between them can be described as follow, an abstraction of the definition of AsyncRpcResult:
```
  
   Public class AsyncRpcResult implements CompletionStage {
       ......
  }
 
```
AsyncRpcResult is a future representing an unfinished RPC call, while AppResponse is the actual return type of this call. In theory, AppResponse doesn't have to implement the {@link Result} interface, this is done mainly for compatibility purpose.
