Hi all I was curious about the various design patterns used in Max's book. I know he used the Adapter pattern. I would like to know the details of all the patterns he used in the sample application and where he used them in Application. That way i would have a full understanding of when and how to use a design pattern. I have the book by the "Gang-of 4" but even though they presented a sample app in their book i would like to know how it also relates to Max's sample app so as to get a better understanding of the different patterns. Thanks a lot as you answer.
