Class ThreadSafeLanguageDetectorME

java.lang.Object

opennlp.tools.langdetect.ThreadSafeLanguageDetectorME

All Implemented Interfaces:

AutoCloseable, opennlp.tools.langdetect.LanguageDetector

@ThreadSafe
public class ThreadSafeLanguageDetectorME
extends Object
implements opennlp.tools.langdetect.LanguageDetector, AutoCloseable

A thread-safe version of the LanguageDetectorME. Using it is completely transparent. You can use it in a single-threaded context as well, it only incurs a minimal overhead.

Note:
This implementation uses a ThreadLocal. Although the implementation is lightweight because the model is not duplicated, if you have many long-running threads, you may run into memory problems.

Be careful when using this in a Jakarta EE application, for example.

The user is responsible for clearing the ThreadLocal via calling close().
