Detailed Description

Accessor class for iterators into sparsity patterns. This class is also the base class for both const and non-const accessor classes into sparse matrices.

Note that this class only allows read access to elements, providing their row and column number (or alternatively the index within the complete sparsity pattern). It does not allow modifying the sparsity pattern itself.
