Detailed Description

template<class Map>
class MappedMatrixColIterator< Map >

Iterator over sparse row of MappedMatrix.

Be careful: Since MappedMatrix is not a real container the entries can only be accessed as copies. Hence the exported type Reference is not a Value&.

As a side effect 'operator->' cannot be used because Dune::ForwardIteratorFacade does not allow to specify a proxy class as Pointer type. Instead it tries to get an address of the result of 'operator*'.

MappedMatrixColIterator()

template<class Map >

MappedMatrixColIterator< Map >::MappedMatrixColIterator ( const Map &  map, typename Matrix::row_type::ConstIterator &&  it, int  row, int  virtualRow, int  virtualCol = 0  )

inline

Construct iterator that points at a specific column.

Parameters

map	The transformation that should be applied to the entries.
it	Iterator pointing to the corresponding column of the untransformed matrix
row	Index of the row of the underlying matrix.
virtualRow	Row number in the set of rows that resulted from transforming the row pointed to by it.
virtualCol	Column number in the set of columns that resulted from transforming the column pointed to by it.
