Detailed Description

template<class T>
class Dune::Singleton< T >

An adapter to turn a class into a singleton.

The class represented by the template parameter T must have a parameterless constructor.

Class T can be publicly derived from Singleton<T>:

#include<dune/common/singleton.hh>
class Foo : public Dune::Singleton<Foo>
{
public:
  Foo()
  {
    bytes = new char[1000];
  }

  ~Foo()
  {
    delete[] bytes;
  }
private:
  char* bytes;
};

Or one can construct a Singleton of an existing class. Say Foo1 is a class with parameterless constructor then

typedef Dune::Singleton<Foo1> FooSingleton;
Foo1 instance& = FooSingleton::instance();

Creates a singleton of that class and accesses its instance.
