Re: [icu-support] Collator c++ caching ; how to reset a collator instance to factory/ctor state?

[Markus S. <mar...@gm...>]

When you cache an object, you should not modify it. So don't
get-modify-use-reset-putback.

You should also not fetch a collator for each string comparison, neither
from scratch nor from a cache. You should at least reuse it for a whole
larger operation, for example sorting a list of strings. Getting one each
time may or may not be fast enough then.

If you do need to cache, then you could either cache with options
(potentially big cache), or cache without options, clone the cached
collator, modify, use, and delete the clone. Cloning a collator should be
fast.
