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>;
    Foo() {}

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.
