Class GlyphPositioningTable.PairSubtable

    • Constructor Detail

      • PairSubtable

        PairSubtable​(java.lang.String id,
                     int sequence,
                     int flags,
                     int format,
                     GlyphCoverageTable coverage,
                     java.util.List entries)
    • Method Detail

      • getType

        public int getType()
        Specified by:
        getType in class GlyphSubtable
        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 class GlyphPositioningSubtable
        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 interface GlyphPositioning
        Overrides:
        position in class GlyphPositioningSubtable
        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.
      • getPairValues

        public abstract GlyphPositioningTable.PairValues getPairValues​(int ci,
                                                                       int gi1,
                                                                       int gi2)
        Obtain associated pair values.
        Parameters:
        ci - coverage index
        gi1 - first input glyph index
        gi2 - second input glyph index
        Returns:
        pair values or null if none applies
