I've been trying different approaches, sorry I couldn't find
a nice
solution.
The only way I see is change all Flag... to an explicit array:
V remove(Object key, Flag... flags);
would become
V remove(Object key);
AND
V remove(Object key, Flag[] flags);
(having both signatures)
This would force the creation of an array if you want any flag, I
don't like it much.
Logging a warning would be way better than doing nothing.
May I drop in two other approaches?
* Rename one of the methods to remove ambiguity altogether.
* Overload like this:
V remove(Object key);
V remove(Object key, Flag flag); // optional, would create collision in
Cache<K, Flag>
V remove(Object key, Flag flagHead, Flag... flagRest); // unweildy
Varargs are too convenient to lose the syntactic benefits, IMO :)
I would prefer the first option, myself. But for consistency's sake it would
require renaming flag-taking variants of all mehods (and possibly other
variants too).
