      public class ThaiTokenizer
      extends SegmentingTokenizerBase

  Tokenizer that use `BreakIterator` to tokenize Thai text.

  WARNING: this tokenizer may not be supported by all JREs. It is known to work with Sun/Oracle and Harmony JREs. If your application needs to be fully portable, consider using ICUTokenizer instead, which uses an ICU Thai BreakIterator that will always be available.
