      public final class OpenNLPTokenizer
      extends SegmentingTokenizerBase

  Run OpenNLP SentenceDetector and Tokenizer. The last token in each sentence is marked by setting the `EOS_FLAG_BIT` in the FlagsAttribute; following filters can use this information to apply operations to tokens one sentence at a time.
