respondToRequest

protected CompletableFuture<Void> respondToRequest(org.apache.flink.shaded.netty4.io.netty.channel.ChannelHandlerContext ctx,

                                            throws RestHandlerException

从类复制的说明: AbstractHandler

Respond to the given HandlerRequest.

指定者:

respondToRequest 在类中 AbstractHandler<RestfulGateway,EmptyRequestBody,M extends TaskManagerMessageParameters>

参数:

ctx - channel handler context to write the response

httpRequest - original http request

handlerRequest - typed handler request

gateway - leader gateway

返回:

Future which is completed once the request has been processed

抛出:

RestHandlerException - if an exception occurred while responding
