Constructor Detail

### GlyphTable.ChainedClassSequenceRule

    public GlyphTable.ChainedClassSequenceRule(GlyphTable.RuleLookup[] lookups,
                                               int inputSequenceLength,
                                               int[] classes,
                                               int[] backtrackClasses,
                                               int[] lookaheadClasses)

  Instantiate a ChainedClassSequenceRule.

  Parameters:
    `lookups` - the rule's lookups
    `inputSequenceLength` - number of glyphs constituting input sequence (to be consumed)
    `classes` - the rule's input glyph class sequence to match, starting with second glyph in sequence
    `backtrackClasses` - the rule's backtrack glyph class sequence to match, starting with first glyph in sequence
    `lookaheadClasses` - the rule's lookahead glyph class sequence to match, starting with first glyph in sequence

Method Detail

### getBacktrackClasses

    public int[] getBacktrackClasses()

  Returns:
    the backtrack classes

### getLookaheadClasses

    public int[] getLookaheadClasses()

  Returns:
    the lookahead classes

### toString

    public java.lang.String toString()

  Overrides:
    `toString` in class `GlyphTable.ClassSequenceRule`
