Detailed Description

template<class GridFunction, class GV, template< class > class DerivativeTraits = Dune::Functions::DefaultDerivativeTraits>
class Dune::Functions::CoarseFunctionOnFineGridView< GridFunction, GV, DerivativeTraits >

A wrapper representing a coarse grid function on a fine gridview.

Template Parameters

GridFunction	Type of the wrapped grid function
GV	Type of the target grid view this function should act on

This wraps a grid function such that it can be used as a GridViewFunction on a user-provided GridView under the following assumptions:

1. The grid function's entity set and the GridView belong to the same grid.
2. The entity set is coarser than the GridView in the sense that any element from the GridView has an ancestor in the entity set.
