Detailed Description

template<class ACCESSOR>
class MatrixIterator< ACCESSOR >

Iterator for constant and non-constant matrices.

This iterator is abstracted from the actual matrix type and can be used for any matrix having the required ACCESSOR type.

Member Typedef Documentation

size_type

template<class ACCESSOR>

using MatrixIterator< ACCESSOR >::size_type = types::global_dof_index

Declare type for container size.

Definition at line 41 of file matrix_iterator.h.

MatrixType

template<class ACCESSOR>

using MatrixIterator< ACCESSOR >::MatrixType = typename ACCESSOR::MatrixType

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

Constructor & Destructor Documentation

MatrixIterator() [1/2]

template<class ACCESSOR >

MatrixIterator< ACCESSOR >::MatrixIterator ( MatrixType *  matrix, const size_type  row = 0, const size_type  index = 0  )

inline

Constructor. Create an iterator into the matrix matrix for the given row and the index within it.

Definition at line 132 of file matrix_iterator.h.

MatrixIterator() [2/2]

template<class ACCESSOR >

template<class OtherAccessor >

MatrixIterator< ACCESSOR >::MatrixIterator ( const MatrixIterator< OtherAccessor > &  other )

inline

Copy from another matrix iterator. Mostly implemented to allow initialization of a constant iterator from a non constant, this function only requires that a conversion from the other iterator's accessor to this accessor object is possible.

Definition at line 141 of file matrix_iterator.h.

Member Function Documentation

operator++() [1/2]

template<class ACCESSOR >

MatrixIterator< ACCESSOR > & MatrixIterator< ACCESSOR >::operator++ ( )

inline

Prefix increment.

Definition at line 149 of file matrix_iterator.h.

operator++() [2/2]

template<class ACCESSOR >

MatrixIterator< ACCESSOR > MatrixIterator< ACCESSOR >::operator++ ( int  )

inline

Postfix increment.

Definition at line 158 of file matrix_iterator.h.

operator*()

template<class ACCESSOR >

const ACCESSOR & MatrixIterator< ACCESSOR >::operator* ( ) const

inline

Dereferencing operator.

Definition at line 167 of file matrix_iterator.h.

operator->()

template<class ACCESSOR >

const ACCESSOR * MatrixIterator< ACCESSOR >::operator-> ( ) const

inline

Dereferencing operator.

Definition at line 174 of file matrix_iterator.h.

operator==()

template<class ACCESSOR >

bool MatrixIterator< ACCESSOR >::operator== ( const MatrixIterator< ACCESSOR > &  other ) const

inline

Comparison. True, if both accessors are equal.

Definition at line 182 of file matrix_iterator.h.

operator!=()

template<class ACCESSOR >

bool MatrixIterator< ACCESSOR >::operator!= ( const MatrixIterator< ACCESSOR > &  other ) const

inline

Inverse of ==.

Definition at line 190 of file matrix_iterator.h.

operator<()

template<class ACCESSOR >

bool MatrixIterator< ACCESSOR >::operator< ( const MatrixIterator< ACCESSOR > &  other ) const

inline

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.

Definition at line 198 of file matrix_iterator.h.

operator>()

template<class ACCESSOR >

bool MatrixIterator< ACCESSOR >::operator> ( const MatrixIterator< ACCESSOR > &  other ) const

inline

Comparison operator. Works in the same way as above operator, just the other way round.

Definition at line 209 of file matrix_iterator.h.
