    • getType

      public int getType()
      Obtain mapping type.
      Overrides:
      getType in class GlyphMappingTable
      Returns:
      mapping format type

      public List getEntries()
      Obtain mapping entries.
      Overrides:
      getEntries in class GlyphMappingTable
      Returns:
      list of mapping entries

    • getClassSize

      public int getClassSize(int set)
      Obtain size of class table, i.e., ciMax + 1, where ciMax is the maximum class index.
      Specified by:
      getClassSize in interface GlyphClassMapping
      Parameters:
      set - for coverage set based class mappings, indicates set index, otherwise ignored
      Returns:
      size of class table

    • getClassIndex

      public int getClassIndex(int gid, int set)
      Map glyph identifier (code) to coverge index. Returns -1 if glyph identifier is not in the domain of the class table.
      Specified by:
      getClassIndex in interface GlyphClassMapping
      Parameters:
      gid - glyph identifier (code)
      set - for coverage set based class mappings, indicates set index, otherwise ignored
      Returns:
      non-negative glyph class index or -1 if glyph identifiers is not mapped by table

    • createClassTable

      public static GlyphClassTable createClassTable(List entries)
      Create glyph class table.
      Parameters:
      entries - list of mapped or ranged class entries, or null or empty list
      Returns:
      a new covera table instance
