Method Detail

onStateTransition

void onStateTransition(State from,
                       State to,
                       Event via)

A state transition has occurred.

Transitions may be internal, i.e. the from and to state are the same.

Listener notification is implemented as a TransitionAction, so take care not to block in this callback as it will block the state machine evaluation as well.

Parameters:

from - the State transitioned from.

to - the State transitioned to.

via - the Event that caused the transition.
