方法详细资料

getOperationKey

protected AsynchronousJobOperationKey getOperationKey(HandlerRequest<EmptyRequestBody,SavepointStatusMessageParameters> 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,SavepointInfo,SavepointStatusMessageParameters>

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 SavepointInfo 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,SavepointInfo,SavepointStatusMessageParameters>

参数:

throwable - failure of the asynchronous operation

返回:

Exceptional operation result

operationResultResponse

protected SavepointInfo operationResultResponse(String 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,SavepointInfo,SavepointStatusMessageParameters>

参数:

operationResult - of the asynchronous operation

返回:

Operation result
