    - #### ChainedGlyphSequenceRule

          public ChainedGlyphSequenceRule(GlyphTable.RuleLookup[] lookups,
                                          int inputSequenceLength,
                                          int[] glyphs,
                                          int[] backtrackGlyphs,
                                          int[] lookaheadGlyphs)

      Instantiate a ChainedGlyphSequenceRule.
      Parameters:
        `lookups` - the rule's lookups
        `inputSequenceLength` - number of glyphs constituting input sequence (to be consumed)
        `glyphs` - the rule's input glyph sequence to match, starting with second glyph in sequence
        `backtrackGlyphs` - the rule's backtrack glyph sequence to match, starting with first glyph in sequence
        `lookaheadGlyphs` - the rule's lookahead glyph sequence to match, starting with first glyph in sequence

  - ### Method Detail

      Returns:
        the backtrack glyphs

    - #### getLookaheadGlyphs

          public int[] getLookaheadGlyphs()

      Returns:
        the lookahead glyphs

    - #### toString

          public String toString()

      Overrides:
