Boost::msm How to initialize state_machine_def and msm::front::state with non-default constructor
I have a state machine look like this:
class FsmDef : public boost::msm::front::state_machine_def {
private:
Args args;
using State = boost::msm::front::state<>;
public:
FsmDef(Args args) : args{args}
{}

BOOST::MSM Checking for state transitions in a guard condition
I have a generic guard condition which I would like to conditionally prevent transitions under certain circumstances. Below is a somewhat C++/Pseudocode of what I would like to do.
bool operator()(Event const& evt, FSM & fsm, SourceState& src,…

boost msm submachine current_state for accessing sub state
any idea how, using boost msm 1_60, I can get the current_state(s) of a submachine? Consider the following code, describing an outer state machine that allows for chosing between two different traffic lights (standard red, yellow, green one and…

How do I get boost.msm to properly change state when using a signal handler to trigger events?
My (boost.msm) state machine appears to 'roll-back' when using signal handlers
to trigger events. However, when I use direct calls to trigger events the state
machine behaves correctly.
I looked in the boost documentation and searched the web, but…

How to Pass data to the current boost meta state machine(MSM) substate
In the following example, while the current execution is still in substate1, I want to pass data to substate1 continuously and then send Event3 or Event1 based on the data. Looks like MSM supports only sending events using (process_event()), but I…

Coupling multiple MSM Statemachines together
My question is more an architectural question. I have multiple statemachines of the same type. Say
controller_type1_sm controller1;
controller_type2_sm controller2;
std::array workers1;
std::array workers2;
Now when…

I am new to c++, boost and using state machines. Does anyone know of an example of polymorphic boost::msm state machine?
I tried to change a transition action to virtual in the basic example provided, but the linker says :
undefined reference to…

periodic state machine with boost statechart
I want to implement a state machine that will periodically monitor some status data (the status of my system) and react to it.
This seems to be something quite basic for a state machine (I've had this problem many times before), but I could not find…

With boost::msm eUML, if I give attributes_ << to the state machine or state, how do I (re)set them?
If I add attributes to an event, I know I can then use the event name like a function...
BOOST_MSM_EUML_EVENT_WITH_ATTRIBUTES(*someEvent*, *someAttributeList*)
someStateMachine.process_event(
someEvent (
valueOfSomeAttribute1, // sets the…
