public class GlyphMappingTable extends java.lang.Object
Base class implementation of glyph mapping table. This base class maps glyph indices to arbitrary integers (mappping indices), and is used to implement both glyph coverage and glyph class maps.
This work was originally authored by Glenn Adams (gadams@apache.org).
