Ah, I see. Ok, makes sense, thanks!

If I'm not mistaken, this is addressed at http://www.boost.org/doc/libs/1_40_0/libs/statechart/doc/rationale.html#Limi..., in the section on "event dispatch to orthogonal regions."

Hi all,
first of all: thanks for the great library!
I just dug into the boost::statechart tutorial trying to figure out how to deal with the following simple scenario: Let's say I have a complex application server represented by a single boost::state_chart with multiple modules (eg. network, database, etc.) represented by orthogonal spaces. I have a couple of system-wide events like "system shutdown". Handling these eventa is generally non-trivial and I'd like all the modules to process it independently. As I understand, statechart tries to deliver an event across al of the orthogonal spaces discarding it once it's processed by any of them (ie. by "return transit", "return discard_event", etc.). But I'd like these events to be delivered to _all_ orthogonal spaces no matter what they do with it.
I could create a state for each of the orthogonal spaces. These wrappers would accept the system-wide events, translate them to local-events, post them locally and forward the system-wide event. But that's basically like having multiple statecharts for each of the modules and dispatching system-wide events manually.
Thanks, Vladimir. _______________________________________________ Boost-users mailing list Boost-users@lists.boost.org http://lists.boost.org/mailman/listinfo.cgi/boost-users
