public final class Gsub extends LookupTableGives access to the 'GSUB' table.
To apply features, the client first resolves a feature tag to a set of lookups, using the
resolveFeatureTagmethod. Then, it invokes the GSUB engine to apply those lookups to the glyph run, using the
applyLookupsmethod. The client passes two objects to
applyLookups, implementing the
Selectorinterfaces respectively. The
Shaperobject is used by the GSUB engine to access the glyphs as well as to report transformations to be done on the glyph run. The
Selectorobject is used by the GSUB engine to learn if the feature should be applied at some positions. Thus, the
Selectorobjects are the bulk of the interface between the client and the GSUB engine.
