Hello,
I have a class that is a singleton. However I need more instances of that class, so I am interested do I have to rewrite the class, or I can adapt it to loose that functionality whithout touch that class?
I don`t want to touch the library class, just to add it an extra feat of not being only Singleton.Code:class MyClass : private SingletonClass { ... MyClass m_instances[3]; };
What possible reason could you have for wanting to inherit from a singleton?Originally Posted by heatblazer
Without changing the class? No - or at least not by any sensible means.
With minimal changes? Unlikely. You're changing a fairly core design assumption, one that may likely have impacted many areas of the original development. You'd have to really understand the original code well, and if you did that, you would already know the work it would take to make this no longer a singleton.

Let`s say I need two instances of that class form pjsua2: 4. Endpoint — PJSUA2 Documentation 1.0-alpha documentation
In that case, pretty much the answer is no. The whole library looks to be designed around that being a singleton.
I would question if you really needed more than one instance - there are good reasons why it's a singleton - and if you really had good reasons, you might need to look elsewhere for a library for your needs.
