transform

public int transform(CtClass clazz,
                     int pos,
                     CodeIterator iterator,
                     ConstPool cp)

Modify GETFIELD, GETSTATIC, PUTFIELD, and PUTSTATIC so that a different field is accessed. The new field must be declared in a superclass of the class in which the original field is declared.
