Detailed Description

template<typename number>
class SparseMatrixIterators::Accessor< number, false >

Accessor class for non-constant matrices, used in the iterators. This class builds on the accessor classes used for sparsity patterns to loop over all nonzero entries, and only adds the accessor functions to gain access to the actual value stored at a certain location.

Definition at line 170 of file sparse_matrix.h.


Member Typedef Documentation

template<typename number >
typedef SparseMatrix<number> SparseMatrixIterators::Accessor< number, false >::MatrixType

Typedef for the type (including constness) of the matrix to be used here.

Definition at line 281 of file sparse_matrix.h.


Constructor & Destructor Documentation

template<typename number >
SparseMatrixIterators::Accessor< number, false >::Accessor ( MatrixType matrix,
const unsigned int  row,
const unsigned int  index 
)

Constructor.

template<typename number >
SparseMatrixIterators::Accessor< number, false >::Accessor ( MatrixType matrix )

Constructor. Construct the end accessor for the given matrix.


Member Function Documentation

template<typename number >
Reference SparseMatrixIterators::Accessor< number, false >::value (  ) const

Value of this matrix entry, returned as a read- and writable reference.

template<typename number >
MatrixType& SparseMatrixIterators::Accessor< number, false >::get_matrix (  ) const

Return a reference to the matrix into which this accessor points. Note that in the present case, this is a non-constant reference.
