方法详细资料

handleRequest

protected R handleRequest(HandlerRequest<EmptyRequestBody> request,
                          AccessExecutionGraph executionGraph)
                   throws RestHandlerException

指定者:

handleRequest 在类中 AbstractAccessExecutionGraphHandler<R extends ResponseBody,M extends CheckpointMessageParameters>

抛出:

RestHandlerException

handleCheckpointRequest

protected abstract R handleCheckpointRequest(HandlerRequest<EmptyRequestBody> request,
                                             AbstractCheckpointStats checkpointStats)
                                      throws RestHandlerException

Called for each request with the corresponding AbstractCheckpointStats instance.

参数:

request - for further information

checkpointStats - for which the handler is called

返回:

Response

抛出:

RestHandlerException - if the handler could not handle the request
