One of the best sources about software design patterns is the “Design Patterns: Elements of Reusable Object-Oriented Software” book by the Gang of Four. Ralph: Some of those languages don't need some of the See A Look Back: Why We Wrote Design Patterns: Elements of Reusable Object-Oriented Software. As I venture further in to disciplines other than Lotus Domino, such as C#, I find myself struggling with some of the base concepts of coding. Singleton is presented as one of the Creational pattern in Gang of Four's famous Design Patterns: Elements of Reusable Object-Oriented Software. Pablo's Topic of the Month for the month of April is about 'Design Patterns: Elements of Reusable Object-Oriented Software' (Addison-Wesley. Well I had to buy 'Design patterns : elements of reusable object-oriented software' as part of the reading list back at uni (over 10 years ago), and have since always referred back to it: For the record, there is considerable disagreement over whether the "Gang of Four" book is really good, or astoundingly bad, for programmers. The examples follow in sections 2 through 4. Still, it is the bible of design patterns after all these years. Then, all you would need to do is to create four instances using the abstract class instead of re-writing three more classes. Design Patterns: Elements of Reusable Object Oriented Software by Erich Gamma, Richard Helm, Ralph Johnson and John Vlissides, popularly known as Gang of Four (GoF). Larry O'Brien recently interviewed three of the Gang of Four about their seminal work on patterns. For many applications, delegates simplify the use of elegant design patterns (Observer, Strategy, State[GoF]) composed of very loosely coupled objects. To test this hypothesis, a real world example was sought for each of the 23 Gang of Four Patterns . Between objects that have been adapted to deal with certain forces can be observed both in the "real world" and in software objects. More recently, C# has popularized the delegate concept, contributing to the success of that language. Larry teased the interview's readers for awhile, but he eventually Erich: Just as an aside, it is also easy to forget that we wrote design patterns before there was Java or C#. ISBN 0-201-63361-2), the seminal Most of the design patterns covered in the GoF book are applicable to .NET and worth being aware of, Another view on the definition of a Design Pattern is that it's a plug used to fill a hole in your programming language (Command pattern, meet C#'s delegate). Standard C++ does not have true object-oriented function pointers. Now that ActionScript is reengineered from top to bottom as a true object-oriented programming (OOP) language, reusable design patterns are an ideal way to solve common problems in Flash and Flex applications One key, important element, of design patterns is that they make changing a program much easier. This paper presents a real world, non software instance of each design pattern from the book, Design Patterns - Elements of Reusable Object-Oriented Software .
