This concept is used when you want some information stored in one object, in C# by the introduction of “Events and Delegates” concept. Delphi's implementation of interfaces lacks of either a garbage collector (as C# or Java do (ab)use), or at least a native weak reference support (as with Apple's ARC model). Classical formulation of it could be found in “Design Patterns, Elements of Reusable Object Oriented Software” by Erich Gamma, Richard Helm, Ralph Johnson, and John Vlissides (The Gang of Four). I began myself writing a series of Delphi examples aiming to explain the classic design patterns as defined in "Design Patterns (Elements of reusable Object-Oriented Software)" by the "Gang of Four" (GOF). Singleton is presented as one of the Creational pattern in Gang of Four's famous Design Patterns: Elements of Reusable Object-Oriented Software. The resolution of the problem is easier in C#, because all classes are inherited from the same “object” class. I never finished the series for lack of time. The infamous (that's them pictured- honest) Gang of Four: Erich Gamma, Richard Helm, Ralph Johnson, and John Vlissides published their famous book 'Design Patterns, Elements of Reusable Object-Oriented Software'. The most talked about books were “Design Patterns: Elements of Reusable Object Oriented Software” by GOF, and “Head First Design Patterns”. World code, it is more difficult than expected.
