Detailed Description

template<typename InstanceType>
class LibCarna::base::Singleton< InstanceType >

Singleton base class

Parameters

InstanceType

Names the class, which derives from this class.

Example of usage:

class Config : public LibCarna::base::Singleton< Config >
{
protected:
 
    friend class LibCarna::base::Singleton< Config >
    Config();
};

If you do require a special implementation of the default constructor, than there is no need for the friend class declaration.
