Detailed Description#

Read-Only Sparse Matrix Iterator.

Here is how to use the iterator to compute the sum of floating-point sparse matrix elements:

SparseMatConstIterator it = m.begin(), it_end = m.end();
double s = 0;
CV_Assert( m.type() == CV_32F );
for( ; it != it_end; ++it )
   s += it.value<float>();

Constructor & Destructor Documentation#

SparseMatConstIterator()#

cv::SparseMatConstIterator::SparseMatConstIterator()

the default constructor

SparseMatConstIterator()#

cv::SparseMatConstIterator::SparseMatConstIterator(const SparseMat * _m)

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

SparseMatConstIterator()#

cv::SparseMatConstIterator::SparseMatConstIterator(const SparseMatConstIterator & it)

the copy constructor

Member Function Documentation#

node()#

const SparseMat::Node * cv::SparseMatConstIterator::node()

returns the current node of the sparse matrix. it.node->idx is the current element index

operator++()#

SparseMatConstIterator & cv::SparseMatConstIterator::operator++()

moves iterator to the next element

operator++()#

SparseMatConstIterator cv::SparseMatConstIterator::operator++(int)

moves iterator to the next element

operator–()#

SparseMatConstIterator & cv::SparseMatConstIterator::operator–()

moves iterator to the previous element

operator–()#

SparseMatConstIterator cv::SparseMatConstIterator::operator–(int)

moves iterator to the previous element

operator=()#

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

the assignment operator

seekEnd()#

void cv::SparseMatConstIterator::seekEnd()

moves iterator to the element after the last element

value()#

template<typename _Tp>
const _Tp & cv::SparseMatConstIterator::value()

template method returning the current matrix element
