template<typename T> struct SingletonAccessor¶

SingletonAccessor struct.

Provides access to singleton instances of classes.

class MySingleton {
private:
     MySingleton() = default; // Prevent direct instantiation
public:
     void doSomething() {}
     friend RaeptorCogs::SingletonAccessor<MySingleton>;
};
// Access the singleton instance
MySingleton& instance = RaeptorCogs::SingletonAccessor<MySingleton>::get();
instance.doSomething();

Template Parameters:: T – The class type to manage as a singleton.

Public Static Functions

static inline T &get()¶

Get the singleton instance of the class T.

Note

The constructor of T must be private or protected, and SingletonAccessor must be declared as a friend of T. Accessing this method will create the instance on first call and return a reference to it.

Returns:: Reference to the singleton instance of T.
