Method Details

getEntries

public List getEntries()

Specified by:

getEntries in class GlyphSubtable

Returns:

this subtable's lookup entries

getLookups

public GlyphTable.RuleLookup[] getLookups(int ci,
 int gi,
 GlyphSubstitutionState ss,
 int[] rv)

Obtain rule lookups set associated current input glyph context.

Specified by:

getLookups in class GlyphSubstitutionTable.ChainedContextualSubtable

Parameters:

ci - coverage index of glyph at current position

gi - glyph index of glyph at current position

ss - glyph substitution state

rv - array of ints used to receive multiple return values, must be of length 1 or greater

Returns:

array of rule lookups or null if none applies

matches

private boolean matches(GlyphSubstitutionState ss,
 GlyphClassTable cdt,
 int[] classes,
 int offset,
 int[] rv)

resolveLookupReferences

public void resolveLookupReferences(Map<String, GlyphTable.LookupTable> lookupTables)

Resolve references to lookup tables, e.g., in RuleLookup, to the lookup tables themselves.

Overrides:

resolveLookupReferences in class GlyphSubtable

Parameters:

lookupTables - map from lookup table identifers, e.g. "lu4", to lookup tables

populate

private void populate(List entries)
