Is LanguageDetector thread-safe?

[Vasniktel]

Is it safe to call methods on the same LanguageDetector object from different threads?

Yes, it is thread-safe. Otherwise, the parallel variants of the LanguageDetector methods would not work because they do exactly that, namely sharing the same instance across multiple threads.

In order to make the library thread-safe, the only thing necessary was to wrap the HashMaps which hold the language models in RwLocks.
