handleRequest

public CompletableFuture<AsynchronousOperationResult<AsynchronousOperationInfo>> handleRequest(@Nonnull
                                                                                               HandlerRequest<EmptyRequestBody> request,

从类复制的说明: AbstractRestHandler

This method is called for every incoming request and returns a CompletableFuture containing a the response.

Implementations may decide whether to throw RestHandlerExceptions or fail the returned CompletableFuture with a RestHandlerException.

Failing the future with another exception type or throwing unchecked exceptions is regarded as an implementation error as it does not allow us to provide a meaningful HTTP status code. In this case a HttpResponseStatus.INTERNAL_SERVER_ERROR will be returned.

覆盖:

handleRequest 在类中 AbstractAsynchronousOperationHandlers.StatusHandler<RestfulGateway,AsynchronousOperationInfo,RescalingStatusMessageParameters>

参数:

request - request that should be handled

gateway - leader gateway

返回:

future containing a handler response

抛出:

RestHandlerException - if the handling failed

getOperationKey

protected AsynchronousJobOperationKey getOperationKey(HandlerRequest<EmptyRequestBody> request)

从类复制的说明: AbstractAsynchronousOperationHandlers.StatusHandler

Extract the operation key under which the operation result future is stored.

指定者:

getOperationKey 在类中 AbstractAsynchronousOperationHandlers.StatusHandler<RestfulGateway,AsynchronousOperationInfo,RescalingStatusMessageParameters>

参数:

request - with which the status handler has been called

返回:

Operation key under which the operation result future is stored

exceptionalOperationResultResponse

protected AsynchronousOperationInfo exceptionalOperationResultResponse(Throwable throwable)

从类复制的说明: AbstractAsynchronousOperationHandlers.StatusHandler

Create an exceptional operation result from the given Throwable. This method is called if the asynchronous operation failed.

指定者:

exceptionalOperationResultResponse 在类中 AbstractAsynchronousOperationHandlers.StatusHandler<RestfulGateway,AsynchronousOperationInfo,RescalingStatusMessageParameters>

参数:

throwable - failure of the asynchronous operation

返回:

Exceptional operation result

operationResultResponse

protected AsynchronousOperationInfo operationResultResponse(Acknowledge operationResult)

从类复制的说明: AbstractAsynchronousOperationHandlers.StatusHandler

Create the operation result from the given value.

指定者:

operationResultResponse 在类中 AbstractAsynchronousOperationHandlers.StatusHandler<RestfulGateway,AsynchronousOperationInfo,RescalingStatusMessageParameters>

参数:

operationResult - of the asynchronous operation

返回:

Operation result
