it turns out my answer was incorrect, or at least incomplete. If you have no submachine, then there might be a way around. If you write: p.process_event(pause); where pause is an eUML event, true, it cannot work. However, this works: any_number_event evpause(pause); p.process_event(evpause);
I forgot to add the definition of any:number_event as it was in another thread: BOOST_TYPE_ERASURE_MEMBER((has_getNumber), getNumber, 0); //type erasure event typedef ::boost::mpl::vector< has_getNumber<int(), const boost::type_erasure::_self>, boost::type_erasure::relaxed_match, boost::type_erasure::copy_constructible<>, boost::type_erasure::typeid_<>
any_number_event_concept; struct any_number_event : boost::type_erasure::any<any_number_event_concept>, msm::front::euml::euml_event<any_number_event> { template <class U> any_number_event(U const& u): boost::type_erasure::any<any_number_event_concept> (u){} any_number_event(): boost::type_erasure::any<any_number_event_concept> (){} };
Used like this: namespace boost { namespace msm{ template<> struct is_kleene_event< any_number_event > { typedef boost::mpl::true_ type; }; }} any_number_event number_event; stt: Playing + number_event / pause_playback == Paused
