Return	Name	Description
	`SparseMatConstIterator()`	the default constructor

`SparseMatConstIterator &`	`operator--()`	moves iterator to the previous element
`SparseMatConstIterator`	`operator--(int)`	moves iterator to the previous element
`SparseMatConstIterator &`	`operator=(const SparseMatConstIterator & it)`	the assignment operator
`void`	`seekEnd()`	moves iterator to the element after the last element
`const _Tp &`	`value()`	template method returning the current matrix element

Public Attributes#

Detailed Description#

Read-write Sparse Matrix Iterator.

The class is similar to cv::SparseMatConstIterator, but can be used for in-place modification of the matrix elements.

Constructor & Destructor Documentation#

SparseMatIterator()#

cv::SparseMatIterator::SparseMatIterator()

the default constructor

SparseMatIterator()#

cv::SparseMatIterator::SparseMatIterator(const SparseMatIterator & it)

the copy constructor

SparseMatIterator()#

cv::SparseMatIterator::SparseMatIterator(SparseMat * _m)

the full constructor setting the iterator to the first sparse matrix element

SparseMatIterator()#

cv::SparseMatIterator::SparseMatIterator(
SparseMat * _m,
const int * idx )

the full constructor setting the iterator to the specified sparse matrix element

Member Function Documentation#

node()#

SparseMat::Node * cv::SparseMatIterator::node()

returns pointer to the current sparse matrix node. it.node->idx is the index of the current element (do not modify it!)

operator++()#

SparseMatIterator & cv::SparseMatIterator::operator++()

moves iterator to the next element

operator++()#

SparseMatIterator cv::SparseMatIterator::operator++(int)

moves iterator to the next element

operator=()#

SparseMatIterator & cv::SparseMatIterator::operator=(const SparseMatIterator & it)

the assignment operator

value()#

template<typename _Tp>
_Tp & cv::SparseMatIterator::value()

returns read-write reference to the current sparse matrix element
