类 AppResponse

java.lang.Object

java.util.concurrent.CompletableFuture<Result>

org.apache.dubbo.rpc.AbstractResult

org.apache.dubbo.rpc.AppResponse

所有已实现的接口:

Serializable, CompletionStage<Result>, Future<Result>, Result

直接已知子类:

DecodeableRpcResult

public class AppResponse
extends AbstractResult
implements Serializable

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 does'n have to implement the {@link Result} interface, this is done mainly for compatibility purpose.

                throws Throwable

从接口复制的说明: Result

Recreate.

if (hasException()) { throw getException(); } else { return getValue(); }

指定者:

recreate 在接口中 Result

返回:

result.

抛出:

Throwable

getValue

public Object getValue()

从接口复制的说明: Result

Get invoke result.

指定者:

getValue 在接口中 Result

返回:

result. if no result return null.

setValue

public void setValue(Object value)

指定者:

setValue 在接口中 Result

getException

public Throwable getException()

从接口复制的说明: Result

Get exception.

指定者:

getException 在接口中 Result

返回:

exception. if no exception return null.

setException

public void setException(Throwable e)

指定者:

setException 在接口中 Result

hasException

public boolean hasException()

从接口复制的说明: Result

Has exception.

指定者:

hasException 在接口中 Result

返回:

has exception.

getAttachments

public Map<String,String> getAttachments()

从接口复制的说明: Result

get attachments.

指定者:

getAttachments 在接口中 Result

返回:

attachments.

setAttachments

public void setAttachments(Map<String,String> map)

Append all items from the map into the attachment, if map is empty then nothing happens

指定者:

setAttachments 在接口中 Result

参数:

map - contains all key-value pairs to append

addAttachments

public void addAttachments(Map<String,String> map)

从接口复制的说明: Result

Add the specified map to existing attachments in this instance.

指定者:

addAttachments 在接口中 Result

getAttachment

public String getAttachment(String key)

从接口复制的说明: Result

get attachment by key.

指定者:

getAttachment 在接口中 Result

setAttachment 在接口中 Result

thenApplyWithContext

public Result thenApplyWithContext(Function<Result,Result> fn)

从接口复制的说明: Result

Add a callback which can be triggered when the RPC call finishes.

Just as the method name implies, this method will guarantee the callback being triggered under the same context as when the call was started, see implementation in AsyncRpcResult.thenApplyWithContext(Function)

指定者:

thenApplyWithContext 在接口中 Result

返回:

toString

public String toString()

覆盖:

toString 在类中 CompletableFuture<Result>
