Observer Pattern

Tuesday, 18 March 2008 15:58 by Frimbob

I have been doing some reading on design patterns an in particular the Observer Pattern.

In short the pattern helps to de-couple code modules by providing a third party class that will acts as observers to concrete classes. These observes act as an intermediary to send messages from one class to another.

This avoids having to directly reference other classes using a full qualified name and thus creating a dependency.

I have found some documentation on MSDN on Implementing the observer pattern in .net.

It appears that by using delegates and events offered by the .NET frame work that less code is required than I originally though necessary.

I might use this pattern in my OOP university project if I can get my Lecture to approve of C++/CLI over his much loved classic C++ .

Since I have needed more reference materials for my OOP (object oriented programming) class which uses C++ as the language I have taken out my credit card for some exercise.

I have also Purchased another code-notes book for my XML Class, they are very concise books easy to read, perfect for a quick read in conjunction with class textbooks.
