Detailed Description

template<typename number>
class internals::SparseMatrixIterators::Accessor< number, true >

Accessor class for constant matrices, used in the const_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.

Member Typedef Documentation

template<typename number >
typedef const SparseMatrix<number> internals::SparseMatrixIterators::Accessor< number, true >::MatrixType

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


Constructor & Destructor Documentation

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

Constructor.

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

Constructor. Construct the end accessor for the given matrix.

template<typename number >
internals::SparseMatrixIterators::Accessor< number, true >::Accessor ( const internals::SparseMatrixIterators::Accessor< number, false > &  a  ) 

Copy constructor to get from a non-const accessor to a const accessor.


Member Function Documentation

template<typename number >
number internals::SparseMatrixIterators::Accessor< number, true >::value (  )  const

Value of this matrix entry.

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

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