Detailed Description

template<class GridImp, class EntitySeedImp>
class Dune::EntitySeed< GridImp, EntitySeedImp >

Store a reference to an entity with a minimal memory footprint.

The EntitySeed provides a light-weight way to store an entity. It is supposed to be implemented as memory-efficiently as possible. To get back the actual entity (or, rather, EntityPointer), you need the corresponding grid. On the grid, there is the method entityPointer(const EntitySeed&), which gives you an EntityPointer in exchange for an EntitySeed.
