Detailed Description
template<class T>
class Dune::shared_ptr< T >
A reference counting smart pointer.
It is designed such that it is usable within a std::vector. The contained object is destroyed only if there are no more references to it.
Member Typedef Documentation
template<class T>
| typedef T Dune::shared_ptr< T >::element_type |

This has to have a parameterless constructor.
