Detailed Description

template<typename SState, typename SEvent, typename SFunctor = SEmptyFunctor<SState,SEvent>, typename SUnknownEventStrategy = SThrowStrategy<SEvent>>
class FSM::SStateMachine< SState, SEvent, SFunctor, SUnknownEventStrategy >

Finite state machine template which bounds functions to the states.

Parameters:

	SState	User defined state type.
	SEvent	User defined event type.
	SFunctor	User defined startegy of functions calls. Default strategy is no calls.
	SUnknownEventStrategy	User defined strategy of reacting on the unknown event. Default strategy is throwing an exception.

template<typename SState, typename SEvent, typename SFunctor = SEmptyFunctor<SState,SEvent>, typename SUnknownEventStrategy = SThrowStrategy<SEvent>> SStateMachine& FSM::SStateMachine< SState, SEvent, SFunctor, SUnknownEventStrategy >::AcceptEvent (  const EventType &  Event  )  [inline]

Accepts an event. First the transition will be executed and then the bound functions (if any) will be called. Parameters: Event  An event that should be processed. Returns: A reference to the machine itself. Exceptions: In  case of any exception (default Unknown even strategy, user functor exception etc) the machine will be reset.
