code: @Override
      public void visitCode(Code obj) {
          Method m = getMethod();
          if (!m.isStatic() && "clone".equals(m.getName()) && SIG_VOID_TO_OBJECT.equals(m.getSignature())) {
              super.visitCode(obj);
          }
      }
docs: override the visitor to only continue for the clone method
  
  @param obj
