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).

Method Details

getType

public int getType()

Obtain mapping type.

Returns:

mapping format type

getEntries

public java.util.List getEntries()

Obtain mapping entries.

Returns:

list of mapping entries

getMappingSize

public int getMappingSize()

Obtain size of mapping table, i.e., ciMax + 1, where ciMax is the maximum mapping index.

Returns:

size of mapping table

getMappedIndex

public int getMappedIndex(int gid)

Map glyph identifier (code) to coverge index. Returns -1 if glyph identifier is not in the domain of the mapping table.

Parameters:

gid - glyph identifier (code)

Returns:

non-negative glyph mapping index or -1 if glyph identifiers is not mapped by table
