state-machine

问题 I have created a stepfunction, the definition for this statemachine below ( step-function.json ) is used in terraform (using the syntax in this page:https://docs.aws.amazon.com/sagemaker/latest/APIReference/API_CreateTransformJob.html) The first time if I execute this statemachine, it will create a SageMaker batch transform job named example-jobname , but I need to exeucute this statemachine everyday, then it will give me error "error": "SageMaker.ResourceInUseException", "cause": "Job name

问题 From this page: https://docs.aws.amazon.com/step-functions/latest/dg/input-output-contextobject.html I'm using "TransformJobName.$": "$$.Execution.Name" to define a dynamic SageMaker job name since the name needs to be unique otherwise statemachine will fail When I executed the statemachine, I got the error below: { "resourceType": "sagemaker", "resource": "createTransformJob.sync", "error": "SageMaker.AmazonSageMakerException", "cause": "2 validation errors detected: Value '808bxx-xxxx-xxxx

问题 I am new in MPL and Finite MSM from boost. I would like to iterate the transition table in order to get the associated transition event given 2 the transition states (current, next). I define and I get the transition table (vector50) like this: struct<my_state_machine_>{ (...) struct transition_table : boost::mpl::vector50< a_row < StateA ,eventAB ,StateB ,&my_machine_state_::action>, (...) > {}; }; typedef boost::msm::back::state_machine<my_state_machine_> my_fsm; typedef boost::msm::back:

问题 I wonder if a state machine is just the state pattern at work or if there is actually a difference between those two? I found this article with the bold title "the state design pattern vs state machine" but at the end of the day he only says that the state pattern makes state machines obsolete but then doesn't describe what exactly is a state machine compared to the implementation of the state pattern . 回答1: The way I describe this difference to my colleagues is that state patterns are a more

问题 I am currently learning about syntax analysis, and more especially, top-down parsing. I know the terminology and the difference with bottom-up LR parsers, and since top-down LL parsers are easier to implement by hand, I am looking forward to make my own. I have seen two kinds of approach: The recursive-descent one using a collection of recursive functions. The stack-based and table-driven automaton as shown here on Wikipedia. I am more interested by the latter, for its power and its
