Detailed Description

template<class GridImp>
class Dune::SIntersectionIterator< GridImp >

Mesh entities of codimension 0 ("elements") allow to visit all neighbors, where a neighbor is an entity of codimension 0 which has a common entity of codimension 1 with the entity. These neighbors are accessed via a IntersectionIterator. This allows the implementation of non-matching meshes. The number of neigbors may be different from the number of faces/edges of an element!
