Method Details

createFeatures

public void createFeatures(List<String> features,
 String[] tokens,
 int index,
 String[] preds)

Specified by:

createFeatures in interface opennlp.tools.util.featuregen.AdaptiveFeatureGenerator

setCurrentContext

public void setCurrentContext(String[][] context)

clearForCurrentThread

public void clearForCurrentThread()

Releases the calling thread's per-thread context slot. Call when a worker thread is being returned to a pool, or when the enclosing component is being disposed in a container with classloader isolation, to avoid pinning the thread's context classloader via the ThreadLocal entry.

Same lifecycle contract as the clearThreadLocalState() methods on the ME classes that embed this generator (currently NameFinderME).
