A Remapper using a Map to define its mapping.

/** * A {@link Remapper} using a {@link Map} to define its mapping. * * @author Eugene Kuleshov */
public class SimpleRemapper extends Remapper { private final Map<String, String> mapping;
Constructs a new SimpleRemapper with the given mapping.
Params:
  • mapping – a map specifying a remapping as follows:
    • for method names, the key is the owner, name and descriptor of the method (in the form <owner>.<name><descriptor>), and the value is the new method name.
    • for invokedynamic method names, the key is the name and descriptor of the method (in the form .<name><descriptor>), and the value is the new method name.
    • for field names, the key is the owner and name of the field (in the form <owner>.<name>), and the value is the new field name.
    • for internal names, the key is the old internal name, and the value is the new internal name.
