Ask help for boost::statechart in PG

[star fan]

I ask the question because I am not good at boost::statechart and I
can't get answer from other way.

To help me to good understand the PG statechart, I hope someone answer
below questions:
In Initial state,
1. why there is not react function for custom_reaction< NullEvt >
2. why there is not custom_reaction definition about
boost::statechart::result react(const MNotifyRec&);

Regards
Vincent

One thing to keep in mind is that the states form a hierarchy. If a state
doesn't explicitly handle/react to an event, the parent will. You'll
notice that Reset and Started both react to NullEvt, and the other states
are substates/children of those.

NullEvt event is handled by react(const boost::statechart::event_base&)

2. why there is not custom_reaction definition about boost::statechart::result react(const MNotifyRec&)

But I can't find any children of Initial which has definition about
MNotifyRec event. Is Primary a children of Initial?

Do I understand correct?
