Detailed Description

template<class Coordinates>
class Dune::YGridComponent< Coordinates >::Iterator

Iterator class allows one to run over all cells of a grid. The cells of the grid to iterate over are numbered consecutively starting with zero. Via the index() method the iterator provides a mapping of the cells of the grid to a one-dimensional array. The number of entries in this array must be the size of the grid.
