Detailed Description

template<int codim, class Grid, class IteratorImp>
class Dune::EntityIterator< codim, Grid, IteratorImp >

interface class for an iterator over grid entities

An entity iterator is an iterator over a subset of entities within a hierarchical grid.

Examples of entity iterators are:

• iterators over the leaf level (LeafGridView::Iterator)
• iterators over a grid level (LevelGridView::Iterator)
• iterators over the children of an entity (Grid::HierarchicIterator)

Template Parameters

codim	codimension of entities this iterator walks over
Grid	type of the grid implementation
IteratorImp	type of the iterator implementation
