Detailed Description

template<class GridView>
class Dune::VTKWriter< GridView >::CornerIterator

Iterate over the elements' corners.

This class iterates over the elements, and within the elements over the corners. Each vertex in the grid can be a corner in multiple elements, and is visited once for each element it is associated with. This class differs from VertexIterator in that it visits the corners of a given element in VTK-ordering, and that it always visits a given vertex once for each element where that vertex is a corner in, independent of the data mode dm.

Dereferencing the iterator yields the current entity. Another useful method on the iterator itself is id(), which returns the number of the current corners associated vertex, in the numbering given by the iteration order of VertexIterator.
