Using a Visitor Pattern to apply the Law of Demeter?

Question

I don't understand how to use Law of Demeter (LoD) with hierarchical classes and the Visitor Pattern.
The hierarchy of classes is for example (with relationships): Article [m:m] Supplier [m:1] Address.
If I want to set the address, I would normally have to code something like: article.getSupplier(4711).getAddress().setStreet("G.W. Bush Street 1"); // ironic
I don't know much of LoD, but I think this example violates it heavily.
How does the solution for this example look like with respecting LoD by using a Visitor Pattern?
And what do you think about it?

Answer 1

TO use the visitor pattern all the visited objects
must have a common interface, and I don't see one
between Supplier, Address and Article.I think they don't need a common interface. Look at the sample code:
package test;
class VisitorPattern {
     public static void main(String[] args) {
          Cheese cheese1 = new Wensleydale();
          Cheese cheese2 = new Gouda();
          Cheese cheese3 = new Brie();
          Visitor v = new VisitorImpl();
          cheese1.accept(v);
          cheese2.accept(v);
          cheese3.accept(v);
interface Visitor {
     void visit(Wensleydale w);
     void visit(Gouda g);
     void visit(Brie b);
class VisitorImpl implements Visitor {
     public void visit(Wensleydale w) {
          System.out.println(w.wensleydaleName());
     public void visit(Gouda g) {
          System.out.println(g.goudaName());
     public void visit(Brie b) {
          System.out.println(b.brieName());
interface Cheese {
     void accept(Visitor v);
abstract class BaseCheese implements Cheese {
class Wensleydale extends BaseCheese {
     String wensleydaleName() {
          return "This is wensleydale";
     public void accept(Visitor v) {
          v.visit(this);
class Gouda extends BaseCheese {
     String goudaName() {
          return "This is gouda";
     public void accept(Visitor v) {
          v.visit(this);
class Brie extends BaseCheese {
     String brieName() {
          return "This is brie";
     public void accept(Visitor v) {
          v.visit(this);
