Hierarchical States：How do I get the child state

[FrostedMonkey]

When I use ObjectStateMachine to retrieve the current state machine state, I get the top-level state. How do I get the child state

State<States, Events> getState(State<States, Events> initialState) {
        if (!initialState.isSubmachineState()) {
            return initialState;
        }
        StateMachine<States, Events> submachine = 
        ((AbstractState<States, Events>) initialState).getSubmachine();
        State<States, Events> state = submachine.getState();
        return getState(state);
    }
