Detailed Description

template<class T, class F = NewObject<T>, int instance = 0>
class Singleton< T, F, instance >

Restricts the instantiation of a class to one static object without locks.

Template Parameters
Tthe class or type
Fthe object factory for T
instancethe initiali instance count

This class safely initializes a static object in a multithreaded environment without using locks (for portability). Note that if two threads call Ref() at the same time, they may get back different references, and one object may end up being memory leaked. This is by design.

Member Function Documentation

template<class T , class F , int instance>
const T & Singleton< T, F, instance >::Ref (   ...) const

Return a reference to the inner Singleton object.

Ref() is used to create the object using the object factory. The object is only created once with the limitations discussed in the class documentation.
