Class ThreadSafeSentenceDetectorME

java.lang.Object
opennlp.tools.sentdetect.ThreadSafeSentenceDetectorME
All Implemented Interfaces:
AutoCloseable, SentenceDetector
@ThreadSafe public class ThreadSafeSentenceDetectorME extends Object implements SentenceDetector, AutoCloseable
A thread-safe version of SentenceDetectorME. Using it is completely transparent. You can use it in a single-threaded context as well, it only incurs a minimal overhead.

Note, however, that 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.
