Hi Takatoshi,
Thank you for your effort and commit. I am really impressed at your brilliant solution! I modified my example using the new any supports. See 41_FingerPrintExampleAnyEvent.cpp
Ah yes, there is even some enable_if! Now this looks like C++ ;-)
It works perfectly.
Good! :)
As you mentioned, your solution not only improves the sub-machines' reusability but also provides access to events. This is something that I really want to.
And can be used in every context, not just with submachines. Furthermore, the mechanism is easily extendable to be used with another any than Boost.Any (like, say, TypeErasure). Looks like our discussion was useful :)
Exactly. I think that Boost.Msm and type erasure mechanism are good combination.
Let me clarify my understanding. msm::front::none is a completion_event. A transition that corresponds to completion_event can be processed without trigger events. Kleene event is not a completion_event. Therefore, it is not invoked without trigger events, but any events are accepted as a trigger. Furthermore, the trigger event is preserved as boost::any.
Yes you got it. A completion event happens immediately, without a call to process_event. A Kleene is an event which matches any event. So, without a call to process_event, nothing happens. I named it kleene so that people familiar with regex see more easily what it is.
By the way, I'm writing the guideline for UML modelers. My goal is to describe how to implement Each UML element into Boost.Msm. Maybe I talked about it last year. And it is coming along some extent now. http://redboltz.wikidot.com/boost-msm-guide
Ah yes, I saw it some time ago, but now it's much more complete. Do you mind if I point to it in the doc?
Of course not. I would appreciate it, if you would do that.
Do you plan to do the same with eUML?
Yes. But first, I will write about several topics such as orthogonal regions and information propagation approach between sub-machine and parent machine on functor front-end. And then I will start to write about eUML. Thanks, Takatoshi
Regards,
Christophe
