Detailed Description

template<class GridImp>
class Dune::SubGridPart< GridImp >

A class to represent a part of a grid, similar to a GridView.

The differences from a GridView are:

The SubGridPart consists of a set of elements (codim 0 entities), considered to be Interior, and their neighbours, considered to be Overlap.
When iterating over intersections on the elements, and accessing the outside() elements, this can give you access to grid entities that are not in the SubGridPart itself. This can only happen for intersections in the Overlap part. For intersections of elements in the Interior part, the outside() element will be either Interior or Overlap.

Constructor & Destructor Documentation

template<class GridImp>

Dune::SubGridPart< GridImp >::SubGridPart	(	const Grid &	grid,
		std::vector< typename Codim< 0 >::Entity::EntitySeed > &&	seeds,
		const bool	overlap = true )

inline

Construct a view of the codim 0 entities that can be constructed from the seeds input.

The seeds input is moved from and will be in a valid but indeterminate state after the call.

template<class GridImp>

template<int cd>

Codim< cd >::Iterator Dune::SubGridPart< GridImp >::begin ( ) const

inline

obtain number of entities with a given geometry type

obtain begin iterator for this view

template<class GridImp>

int Dune::SubGridPart< GridImp >::size ( int codim ) const

inline

obtain the index set

obtain number of entities in a given codimension
