Gang of four is nothing to do with technical sense, it's name of four authors(Erich Gamma, Richard Helm, Ralph Johnson and John Vlissides) of book Design Patterns: Elements of Reusable Object-Oriented Software. The pattern specifications follow the same form as in GOF's Design Patterns: Elements of Reusable Object-Oriented Software. Create a static/shared method within the class that will return a newly created instance of your class, or if an instance already exists then it will return the current instance. A group of authors now affectionately known as the 'Gang of Four' (Erich Gamma, Richard Helm, Ralph Johnson, and John Vilssides) wrote a book called 'Design Patterns: Elements of Reusable Object-Oriented Software'. My own case was grounded in Fortran II and meandered through BASIC, assembly language, FORTH, and then on to Internet languages like JavaScript, PHP, and C#. Can creat an instance of the object. The fifth chapter is the first part of the EDP catalog. In design pattern we often listen the term Gang of Four, GOF, or GO4. In next posts, I will pick each one of original 23 GOF design patterns, discuss pros, cons & need, UML diagrams for patterns and simple code illustration in C#.
