Johan Nilsson wrote: [snipped example of calling virtual functions from a state ctor] I'm too lazy to look in the standard what exactly is allowed w.r.t calling virtual functions from ctors, but I'd very much expect that this should work (since we're *not* calling a function that is potentially overridden in a derived class).
- Is it possible to indicate that a state should exit right away in boost::fsm (I'm not sure what this would be referred to as in FSM terminology - a 'transitional state' perhaps)? E.g.:
struct flush_buffers : fsm::simple_state<...> { flush_buffers() { ... flush ... ... if ok - goto xxx_state ... if fail - return to previous } };
This has nothing to do with ctors/dtors. You cannot just "goto" another state inside an action and therefore entry()/exit() wouldn't change anything here. FSMs usually do this by posting internal events, boost::fsm is no different here. Regards, Andreas
