win32singleton.h File Reference

Detailed Description

Provides helper macros to implement singleton objects:

• __DeclareSingleton put this into class declaration
• __ImplementSingleton put this into the implemention file
• __ConstructSingleton put this into the constructor
• __DestructSingleton put this into the destructor

Get a pointer to a singleton object using the static Instance() method:

Core::Server* coreServer = Core::Server::Instance();
