How to traverse automaton with new api?

[Dmitry Kan]

o.a.l.u.automaton.Automaton api has changed in lucene 4.10 (
https://issues.apache.org/jira/secure/attachment/12651171/LUCENE-5752.patch
).

Method getNumberedStates() got dropped. class State does not exist anymore.

In the Automaton api before 4.10 the traversal could be achieved like this:

// Automaton a;
State[] states = a.getNumberedStates();
    for (State s : states) {
      StringBuilder msg = new StringBuilder();
      msg.append(String.valueOf(s.getNumber()));
      if (a.getInitialState() == s) {
        msg.append(" INITIAL");
      }
      msg.append(s.isAccept() ? " [accept]" : " [reject]");
      msg.append(", " + s.numTransitions + " transitions");
      for (Transition t : s.getTransitions()) {
        // do something with transitions
      }
      log.info(msg);
    }

Can anybody help on how to traverse an existing Automaton object with new
api?

Thanks,
Dmitry
