Hi again,
[snip]
// An action which returns the event's number. BOOST_MSM_EUML_ACTION(GetEventNumber_) { template
int operator()(Evt const& evt, Fsm&, SourceState&, TargetState&) { return evt.getNumber(); } }; // The attribute: BOOST_MSM_EUML_DECLARE_ATTRIBUTE(int, EventNo) BOOST_MSM_EUML_ATTRIBUTES((attributes_ << EventNo), EventNoAttr) // All events that contain this attribute: MY_BOOST_MSM_EUML_EVENT_WITH_ATTRIBUTES_AND_MEMBERS(event1, EventNoAttr, (int getEventNumber() const { return get_attribute(EventNo); }) // <-- members_list ) /* ... more events with same scheme ... */
// Creating an instance of the new "kleene"-event which has // a "getNumber" member-function. any_number_event number_event;
// The transitions table BOOST_MSM_EUML_TRANSITION_TABLE(( State1 + number_event [IsEventNumberGT_<7>()] == State2, State1 + event1 / (fsm_(lastEventNo) = event_(EventNo)) == State3 State2 + kleene / (fsm_(lastEventNo) = GetEventNumber_)) == State3 ), stt)
Of course, I had some more typos. (I did not test, what I extracted from my code into the email... :-/) However, I realized, that for my case I do not really need the "IsEventNumberGT_<VAL>" action. I could as well have used the "GetEventNumber_" action in the transition table which is even clearer for a C++ developer: // The transitions table BOOST_MSM_EUML_TRANSITION_TABLE(( State1 + number_event [GetEventNumber_ > Int_<7>()] == State2, ), stt) Ciao, Deniz PS: I found a possible bug in MSM when accessing state-attributes from actions. But maybe I am doing something wrong. I'll open a new email-thread for that with subject "[MSM] Unable to retrieve correct value of attribute of a state from within actions. (Possible Bug?)". Maybe you could have a look at it.
