Detailed Description

template<class S>
class ThreadSafeSingleton< S >

Template class used to make from a class a singleton.

S is the type of the singleton object to instantiate.
This class permits to gather all singleton code in the same place and not to pollute object interface with singleton methods.
Accessing to the instance of S is made through ThreadSafeSingleton<S>::instance()
Note : The class using this adapter should have constructor and destructor protected and copy constructor and operator= private.
Besides it should declare the class ThreadSafeSingleton<S> friend in order this class can make the construction.
