I prefer, when the Singleton pattern is the best pattern to use, to create the instance as a static member of the class.Thu, 09 Apr 2026 19:28:00 GMThttps://stackoverflow.com/questions/2155688/what-is-a-singleton-in-cA singleton is a class which only allows one instance of itself to be created - and gives simple, easy access to said instance. The singleton premise is a pattern across software development. There is a C# implementation "Implementing the Singleton Pattern in C#" covering most of what you need to know - including some good advice regarding thread safety. To be honest, It's very rare that you ...Thu, 09 Apr 2026 18:16:00 GMThttps://stackoverflow.com/questions/6760685/what-is-the-best-way-of-implementing-a-singleton-in-pythonA singleton is special because its instance is created only once, and a metaclass is the way you customize the creation of a class, allowing it to behave differently than a normal class.Wed, 25 Mar 2026 22:09:00 GMThttps://stackoverflow.com/questions/228164/on-design-patterns-when-should-i-use-the-singletonThe glorified global variable - becomes a gloried global class. Some say breaking object-oriented design. Give me scenarios, other than the good old logger where it makes sense to use the singleton.Thu, 09 Apr 2026 02:17:00 GMThttps://stackoverflow.com/questions/86582/singleton-how-should-it-be-usedSo a singleton should be used if and only if, we need both the traits it offers: If we need global access (which is rare, because globals are generally discouraged) and we need to prevent anyone from ever creating more than one instance of a class (which sounds to me like a design issue).Thu, 09 Apr 2026 16:07:00 GMThttps://stackoverflow.com/questions/733842/what-are-the-real-world-applications-of-the-singleton-patternSimple. What does a singleton do? It provides global access to an instance of an object, and It guarantees that no more than one instance of that type can ever be created. So you use a singleton when you need both of these things. And that is rare. Globals are generally speaking, bad. We tend to avoid them when possible. And building your application around the assumption that "if more than ...Wed, 08 Apr 2026 12:12:00 GMThttps://stackoverflow.com/questions/70689/what-is-an-efficient-way-to-implement-a-singleton-pattern-in-javaThis is useful when your singleton needs to inherit from a superclass. You cannot use the enum singleton pattern in this case, since enums cannot have a superclass (they can implement interfaces, though).Sun, 05 Apr 2026 04:02:00 GMThttps://stackoverflow.com/questions/246710/how-to-implement-a-singleton-in-cHow do I implement the singleton pattern in C#? I want to put my constants and some basic functions in it as I use those everywhere in my project.

I still use quite a lot of singletons, especially for factoryMon, 06 Apr 2026 15:21:00 GMThttps://stackoverflow.com/questions/2094211/difference-between-singleton-and-factory-method-patternThe Singleton pattern ensures that only one instance of the class exists and typically provides a well-known, i.e., global point for accessing it. The Factory pattern defines an interface for creating objects (no limitation on how many) and usually abstracts the control of which class to instantiate.Thu, 09 Apr 2026 03:00:00 GMT
