Hi Daniel,

Another place that is not clear to me is the following (in old code):

 585         // Returns a KnownLevel with the given localized name matching
 586         // by calling the Level.getLocalizedLevelName() method (i.e. found
 587         // from the resourceBundle associated with the Level object).
 588         // This method does not call Level.getLocalizedName() that may
 589         // be overridden in a subclass implementation
590 static synchronized KnownLevel findByLocalizedLevelName(String name) {
591 for (List<KnownLevel> levels : nameToLevels.values()) {
592 for (KnownLevel l : levels) {
593 String lname = l.levelObject.getLocalizedLevelName();
594 if (name.equals(lname)) {
595 return l;
596 }
597 }
598 }
599 return null;
 600         }

In spite of claiming that "this method doesn't call Level.getLocalizedName() that may be overridden in subclass", it does just that. it calls the getLocalizedLevelName on the KnownLevel.levelObject, which is a user-constructed object. You changed the code into:

627 static synchronized Optional<Level> findByLocalizedLevelName(String name,
 628                 Function<KnownLevel, Stream<Level>> selector) {
 629             purge();
 630             return nameToLevels.values()
 631                     .stream()
 632                     .flatMap(List::stream)
 633                     .flatMap(selector)
634 .filter(lo -> name.equals(lo.getLocalizedLevelName()))
 635                     .findFirst();
 636         }

Which calls getLocalizedName() on the Level object selected by the given selector. In line 385 you pass in the selector to select the mirroredLevel, but in line 487, you pass in the selector to select the referent.

So which one is the right one? If you want to obey the comment it should always be the mirroredLevel which is checked against localized name, right?

Regards, Peter

Hi Mandy,

I added an additional selector parameter to the find methods.
This made it possible to return Optional<Level> instead of
KnownLevel - and it does simply the parse() method.

This looks pretty good.

Since KnownLevel is now a Reference, I suggest to change KnownLevel::findByName, findByValue and findByLocalizedLevelName to return Optional<Level> instead such that the parse method implementaiton could be simplified.

We need to return KnownLevel because sometimes we need the
level object and sometimes the mirror.

So either findByName(String name, boolean mirror) or two methods: findLevelByName and findMirroredLevelByName??

Or seriously consider to remove KnownLevel class by introducing a new Level subclass with final Level.getName, Level.getLocalizedName, Level.getResourceBundleName methods??
