org.apache.fop.complexscripts.util.GlyphSequence

A GlyphSequence encapsulates a sequence of character codes, a sequence of glyph codes, and a sequence of character associations, where, for each glyph in the sequence of glyph codes, there is a corresponding character association. Character associations server to relate the glyph codes in a glyph sequence to the specific characters in an original character code sequence with which the glyph codes are associated.
