Dune::YGrid< Coordinates > Class Template Reference

implements a collection of YGridComponents which form a codimension Entities of given codimension c need to be represented by d choose c YgridComponents. All entities in one such component share the same set of spanning unit vectors. A YGrid is used to iterate over the entire set of components the codimension consists of. It doesn't hold any data, but instead holds an iterator range into an array of components (which is owned by YGridLevel). More...
