A SignatureVisitor that remaps types with a Remapper.

/** * A {@link SignatureVisitor} that remaps types with a {@link Remapper}. * * @author Eugene Kuleshov */
public class SignatureRemapper extends SignatureVisitor { private final SignatureVisitor signatureVisitor; private final Remapper remapper; private ArrayList<String> classNames = new ArrayList<>();
Constructs a new SignatureRemapper. Subclasses must not use this constructor. Instead, they must use the SignatureRemapper(int, SignatureVisitor, Remapper) version.
Params:
  • signatureVisitor – the signature visitor this remapper must deleted to.
  • remapper – the remapper to use to remap the types in the visited signature.
