Pull request overview
This PR adjusts the singleton construction pattern to better support singleton subclasses that should not be publicly constructible (e.g., Dmn_Runtime_Manager), by moving construction into Dmn_Singleton and restricting the runtime manager constructor.
Changes:
- Update
Dmn_Singleton<T>::createInstance()to construct viastd::shared_ptr<T>(new T(...))instead ofstd::make_shared<T>(...). - Make
Dmn_Runtime_Managerconstructor non-public and add friendship for itsDmn_Singletonspecialization.
