Accessor< number, Constness > | accessor |
Iterator for constant and non-constant matrices.
The first template argument denotes the underlying numeric type, the second the constness of the matrix.
Since there is a specialization of this class for Constness=false
, this class is for iterators to constant matrices.
Definition at line 297 of file chunk_sparse_matrix.h.
using ChunkSparseMatrixIterators::Iterator< number, Constness >::MatrixType = typename Accessor<number, Constness>::MatrixType |
Typedef for the matrix type (including constness) we are to operate on.
Definition at line 303 of file chunk_sparse_matrix.h.
using ChunkSparseMatrixIterators::Iterator< number, Constness >::value_type = const Accessor<number, Constness> & |
An alias for the type you get when you dereference an iterator of the current kind.
Definition at line 309 of file chunk_sparse_matrix.h.
using ChunkSparseMatrixIterators::Iterator< number, 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 315 of file chunk_sparse_matrix.h.
ChunkSparseMatrixIterators::Iterator< number, Constness >::Iterator | ( | MatrixType * | matrix, |
const unsigned int | row ) |
Constructor. Create an iterator into the matrix matrix
for the given row and the index within it.
ChunkSparseMatrixIterators::Iterator< number, Constness >::Iterator | ( | MatrixType * | matrix | ) |
Constructor. Create the end iterator for the given matrix.
ChunkSparseMatrixIterators::Iterator< number, Constness >::Iterator | ( | const ChunkSparseMatrixIterators::Iterator< number, false > & | i | ) |
Conversion constructor to get from a non-const iterator to a const iterator.
Iterator & ChunkSparseMatrixIterators::Iterator< number, Constness >::operator++ | ( | ) |
Prefix increment.
Iterator ChunkSparseMatrixIterators::Iterator< number, Constness >::operator++ | ( | int | ) |
Postfix increment.
const Accessor< number, Constness > & ChunkSparseMatrixIterators::Iterator< number, Constness >::operator* | ( | ) | const |
Dereferencing operator.
const Accessor< number, Constness > * ChunkSparseMatrixIterators::Iterator< number, Constness >::operator-> | ( | ) | const |
Dereferencing operator.
bool ChunkSparseMatrixIterators::Iterator< number, Constness >::operator== | ( | const Iterator< number, Constness > & | ) | const |
Comparison. True, if both iterators point to the same matrix position.
bool ChunkSparseMatrixIterators::Iterator< number, Constness >::operator!= | ( | const Iterator< number, Constness > & | ) | const |
Inverse of ==
.
bool ChunkSparseMatrixIterators::Iterator< number, Constness >::operator< | ( | const Iterator< number, Constness > & | ) | const |
Comparison operator. Result is true if either the first row number is smaller or if the row numbers are equal and the first index is smaller.
This function is only valid if both iterators point into the same matrix.
bool ChunkSparseMatrixIterators::Iterator< number, Constness >::operator> | ( | const Iterator< number, Constness > & | ) | const |
Comparison operator. Works in the same way as above operator, just the other way round.
int ChunkSparseMatrixIterators::Iterator< number, Constness >::operator- | ( | const Iterator< number, Constness > & | p | ) | const |
Return the distance between the current iterator and the argument. The distance is given by how many times one has to apply operator++ to the current iterator to get the argument (for a positive return value), or operator-- (for a negative return value).
Iterator ChunkSparseMatrixIterators::Iterator< number, Constness >::operator+ | ( | const unsigned int | n | ) | const |
Return an iterator that is n
ahead of the current one.
|
private |
Store an object of the accessor class.
