- ## 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`).
