Detailed Description

Class and macro for implementing singletons.

Definition in file singleton.h.

Macro Definition Documentation

DECLARE_SINGLETON

#define DECLARE_SINGLETON

(

T

)

Value:

namespace Common { \
    template<> T *Singleton<T>::_singleton = 0; \
    }

Note that you need to use this macro from the global namespace.

This is because C++ requires initial explicit specialization to be placed in the same namespace as the template. It has to be put in the global namespace to assure the correct namespace Common is referenced.
