Detailed Description

template<bool Constness>
class TrilinosWrappers::SparseMatrixIterators::Iterator< Constness >

This class acts as an iterator walking over the elements of Trilinos matrices. The implementation of this class is similar to the one for PETSc matrices.

Note that Trilinos stores the elements within each row in ascending order. This is opposed to the deal.II sparse matrix style where the diagonal element (if it exists) is stored before all other values, and the PETSc sparse matrices, where one can't guarantee a certain order of the elements.

Member Typedef Documentation

size_type

template<bool Constness>

using TrilinosWrappers::SparseMatrixIterators::Iterator< Constness >::size_type = ::types::global_dof_index

Declare type for container size.

Definition at line 358 of file trilinos_sparse_matrix.h.

difference_type

template<bool Constness>

using TrilinosWrappers::SparseMatrixIterators::Iterator< Constness >::difference_type = ::types::global_dof_index

A type that denotes what data types is used to express the difference between two iterators.

Definition at line 364 of file trilinos_sparse_matrix.h.

value_type

template<bool Constness>

using TrilinosWrappers::SparseMatrixIterators::Iterator< Constness >::value_type = TrilinosScalar

An alias for the type you get when you dereference an iterator of the current kind.

Definition at line 370 of file trilinos_sparse_matrix.h.

MatrixType

template<bool Constness>

using TrilinosWrappers::SparseMatrixIterators::Iterator< Constness >::MatrixType = typename Accessor<Constness>::MatrixType

Typedef for the matrix type (including constness) we are to operate on.
