All Implemented Interfaces:

Subset

Direct Known Subclasses:

public class SubsetDefaultImpl
extends java.lang.Object
implements Subset

A default implementation for the Subset interface.

This implementation is suitable for subclassing, if specific behaviour is needed beyond the correspondance between subset and full gids.

Constructor Summary

Constructor	Description
SubsetDefaultImpl(int numGlyphs, boolean doSubset)	Create a new subset for a font.

Method Summary

Modifier and Type	Method	Description
boolean	doSubset()
int	getExistingSubsetGid(int fullGid)	Return the currently esisting subset gid corresponding to a full gid, if there is one, without generating a new one.
int	getFullGid(int subsetGid)	Return the full gid corresponding to a subset gid.
int	getNumGlyphs()	Return the number of glyphs in the subset.
int	getSubsetGid(int fullGid)	Return the subset gid corresponding to a full gid.

Constructor Detail

SubsetDefaultImpl

public SubsetDefaultImpl(int numGlyphs,
                         boolean doSubset)
                  throws InvalidFontException,
                         UnsupportedFontException

Create a new subset for a font.

Parameters:

numGlyphs - the number of glyphs in the full font

doSubset - whether to effectively subset

Throws:

InvalidFontException

UnsupportedFontException

Method Detail

doSubset

public boolean doSubset()

getNumGlyphs

public int getNumGlyphs()

Description copied from interface: Subset

Return the number of glyphs in the subset.

Specified by:

getNumGlyphs in interface Subset

getSubsetGid

public int getSubsetGid(int fullGid)
                 throws InvalidFontException,
                        UnsupportedFontException

Description copied from interface: Subset

Return the subset gid corresponding to a full gid.

Specified by:

getSubsetGid in interface Subset

Parameters:

fullGid - the full gid, must be a legal gid for the full font.

Throws:

InvalidFontException

UnsupportedFontException

getFullGid

public int getFullGid(int subsetGid)

Description copied from interface: Subset

Return the full gid corresponding to a subset gid.

Specified by:

getFullGid in interface Subset

Parameters:

subsetGid - the subset gid, must be in the range [0..getNumGlyphs () [

getExistingSubsetGid

public int getExistingSubsetGid(int fullGid)

Description copied from interface: Subset

Return the currently esisting subset gid corresponding to a full gid, if there is one, without generating a new one. Return -1 if the full gid is not in the subset.

Specified by:

getExistingSubsetGid in interface Subset

Parameters:

fullGid - the full gid, must be a legal gid for the full font.
