instance: Basic support for the singleton pattern.

NAME

QuantLib::Singleton - Basic support for the singleton pattern.

SYNOPSIS

#include <ql/patterns/singleton.hpp>

Inherits boost::noncopyable.

Static Public Member Functions

static T & instance ()
access to the unique instance

Detailed Description

template<class T> class QuantLib::Singleton< T >

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.
