    • Method Detail

      • getType

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

      • getEntries

        public java.util.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​(java.util.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
