      Returns:
        the input sequence length

    - #### resolveLookupReferences

          public void resolveLookupReferences(java.util.Map<java.lang.String,GlyphTable.LookupTable> lookupTables)

      Resolve references to lookup tables, e.g., in RuleLookup, to the lookup tables themselves.
      Parameters:
        `lookupTables` - map from lookup table identifers, e.g. "lu4", to lookup tables
