Query the current substate of a parallel region

[Ulrich Schuster]

Hi there

I just started using the squirrel framework - it's great! Thanks very much for developing and sharing!

I am still exploring the framework. My goal is to use is as a mock of a mobile device, so I can test backend functions without actual devices in the field. I have two active regions - on to mimic the wireless connection, which might go down any time; and one for the controller. For a transition between controller states CTRL_A and CTRL_B, I want to set up a guard that enables the transition only if the device is online - that is, if the the WIRELESS region is in state ONLINE. How can I query the current state in the neighboring parallel region from within a Condition<> object?

Thanks very much for your help!

Hi Ulrich,

Sorry for late reply. I am glad you like the library.

I am not quite understand your question, what means "How can I query the current state in the neighboring parallel region from within a Condition<> object"? It would be helpful if you can write some pseudocode to describe your question. And in case you want to query substates of a parallel state, you can try "StateMachine.getSubStatesOn(AParallelState)" which will return substates of current parallel state.

Thanks,

Henry
