Welcome to my Visitor Design Pattern Tutorial! This is the last part of my design pattern video tutorial.

The Visitor design pattern allows you to add methods to classes of different types without much altering to those classes. You can make completely different methods depending on the class used with this pattern.

With both the video and the code above you should be able to start using this pattern in your code easily.
