Advanced Transitions¶

Ignore¶

Use ignore(...) for accepted no-op triggers.

sm.configure(State.A).ignore(Trigger.HEARTBEAT)

Guarded ignore:

sm.configure(State.A).ignore_if(Trigger.HEARTBEAT, guard, "ignore when healthy")

Use reentry when a trigger should refresh the same state and rerun state lifecycle.

sm.configure(State.A).permit_reentry(Trigger.REFRESH)

Internal transitions run actions without changing state.

sm.configure(State.A).internal_transition(Trigger.PING, internal_action)

Dynamic transitions compute destination at runtime:

def pick_destination(args):
    return State.B if args and args[0] else State.C

sm.configure(State.A).dynamic(Trigger.ROUTE, pick_destination)

Guarded dynamic:

sm.configure(State.A).dynamic(
    Trigger.ROUTE,
    pick_destination,
    guard=is_routable,
    guard_description="routing enabled",
)
