Detailed Description

class TrilinosWrappers::SparseMatrixIterators::Accessor< true >

The specialization for a const Accessor.

Definition at line 223 of file trilinos_sparse_matrix.h.

Member Typedef Documentation

◆ MatrixType

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

Definition at line 230 of file trilinos_sparse_matrix.h.

Constructor & Destructor Documentation

◆ Accessor() [1/2]

TrilinosWrappers::SparseMatrixIterators::Accessor< true >::Accessor ( MatrixType matrix,
const size_type  row,
const size_type  index 

Constructor. Since we use accessors only for read access, a const matrix pointer is sufficient.

◆ Accessor() [2/2]

template<bool Other>
TrilinosWrappers::SparseMatrixIterators::Accessor< true >::Accessor ( const Accessor< Other > &  a)

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

Member Function Documentation

◆ value()

TrilinosScalar TrilinosWrappers::SparseMatrixIterators::Accessor< true >::value ( ) const

Value of this matrix entry.
