All Implemented Interfaces:

ClassVisitor

public class SingleImplementationMarker
extends SimplifiedVisitor
implements ClassVisitor

This ClassVisitor investigates all classes that it visits to see whether they have/are the sole (non-abstract) implementation of an interface. It may already modify the access of the single implementing class to match the access of the interface.

Constructor Summary

SingleImplementationMarker(boolean allowAccessModification)
Creates a new SingleImplementationMarker.

SingleImplementationMarker(boolean allowAccessModification, ClassVisitor extraClassVisitor)
