Method Detail
-
getType
public int getType()
- Specified by:
getType
in classGlyphSubtable
- Returns:
- this subtable's type
-
isCompatible
public boolean isCompatible(GlyphSubtable subtable)
Determine if a glyph subtable is compatible with this glyph subtable. Two glyph subtables are compatible if the both may appear in a single lookup table.- Overrides:
isCompatible
in classGlyphPositioningSubtable
- Parameters:
subtable
- a glyph subtable to determine compatibility- Returns:
- true if specified subtable is compatible with this glyph subtable, where by compatible is meant that they share the same lookup type
-
position
public boolean position(GlyphPositioningState ps)
Perform glyph positioning at the current index, mutating the positioning state object as required. Only the context associated with the current index is processed.- Specified by:
position
in interfaceGlyphPositioning
- Overrides:
position
in classGlyphPositioningSubtable
- Parameters:
ps
- glyph positioning state object- Returns:
- true if the glyph subtable applies, meaning that the current context matches the associated input context glyph coverage table; note that returning true does not mean any position adjustment occurred; it only means that no further glyph subtables for the current lookup table should be applied.
-
getValue
public abstract GlyphPositioningTable.Value getValue(int ci, int gi)
Obtain positioning value for coverage index.- Parameters:
ci
- coverage indexgi
- input glyph index- Returns:
- positioning value or null if none applies
-
create
static GlyphPositioningSubtable create(java.lang.String id, int sequence, int flags, int format, GlyphCoverageTable coverage, java.util.List entries)
