#include <dgfparser.hh>
Inherits Dune::MacroGrid.
The constructor of the class is given the filename of the DGF file. From that file a pointer to an instance of type GridType is created by reading the given file which is translated to the specific format of the given GridType. The GridPtr class behaves like an auto pointer of GridType. An auto pointer to a grid of type GridType is constructed as follows:
GridPtr<GridType> gridptr(filename, MPI_COMM_WORLD ); GridType & grid = *gridptr;
