      Modifier and Type Method Description
      void addCID​(int gid, int cid)
      Adds a new GID/CID combination to the charset.
      void addSID​(int gid, int sid, java.lang.String name)
      Adds a new GID/SID/name combination to the charset.
      int getCIDForGID​(int gid)

      int getGIDForCID​(int cid)
      Returns the GID for a given CID.
      (package private) int getGIDForSID​(int sid)
      Returns the GID for the given SID.
      java.lang.String getNameForGID​(int gid)
      Returns the PostScript glyph name for the given GID.
      (package private) int getSID​(java.lang.String name)
      Returns the SID for a given PostScript name, you would think this is not needed, but some fonts have glyphs beyond their encoding with charset SID names.
      (package private) int getSIDForGID​(int gid)
      Returns the SID for a given GID.
      boolean isCIDFont()
      Indicates if the charset belongs to a CID font.
