Right, well first you need to explain what both of those terms mean.
I made debug and I noticed that MissingTransitionException is thrown always and in the method next. I changed the method but the problem is still there.
1. Which 'next' method did you change?
2. What did you change, and why did you think it would make a difference?
BTW, it's usually
very bad practise to change something before you
know what the problem is. And if it was simply done as a
test,
back it out if it doesn't work before you try anything else.
Other than what K.Tsang suggested, I can only say:
1. Your first method appears to be misnamed. From what I can see, it finds the FIRST
Transition where the 'from' state and label match the ones supplied, and returns its 'to' state (which presumably is the from state of the next Transition in sequence). In fact, I wonder if your 2nd method shouldn't simply continue on from where the first one finished - in which case it might be better to have it return the
Transition object, not the
toState.
2. '
transitions' would appear to be a
Collection of
Transition objects, and so is probably an
Iterable. If so, your first method could be re-written as:
Note: this doesn't change its logic in any way, so it won't solve your problem; but it does make it a bit easier to read.
3. Your Transition object seems a bit involved (but maybe it's required). Personally, I'd leave out
toState altogether and replace it with
Transition next;
Then "to" State becomes
next.fromState. But, as I say, maybe you need it for other reasons.
4. I'm not sure what the
Label is used for, and I suspect it may also be part of your problem. Independent equality checks like that can be tricky, unless you can
guarantee that your
Transition objects in 'transitions' are entirely consistent with the checks you're doing.
So, no answers, just questions; but maybe one of them will point you in the right direction.
