Detailed Description
template<class T>
class QuantLib::Singleton< T >
Basic support for the singleton pattern.
The typical use of this class is:
class Foo : public Singleton<Foo> { friend class Singleton<Foo>; private: Foo() {} public: ... };
which, albeit sub-optimal, frees one from the concerns of creating and managing the unique instance and can serve later as a single implemementation point should synchronization features be added.
