- All Known Implementing Classes:
    GlyphClassTable

      public interface GlyphClassMapping

  The `GlyphClassMapping` interface provides glyph identifier to class index mapping support.

    All Methods Instance Methods Abstract Methods
    Modifier and Type | Method and Description
    --- | ---
    `int` | `getClassIndex(int gid, int set)` Map glyph identifier (code) to coverge index.
    `int` | `getClassSize(int set)` Obtain size of class table, i.e., ciMax + 1, where ciMax is the maximum class index.

- - ### Method Detail

    - #### getClassSize

          int getClassSize(int set)

      Obtain size of class table, i.e., ciMax + 1, where ciMax is the maximum class index.
      Parameters:
        `set` - for coverage set based class mappings, indicates set index, otherwise ignored
      Returns:
        size of class table

    - #### getClassIndex

          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.
      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
