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.

§ operator++() [1/2]

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

moves iterator to the next element

§ operator++() [2/2]

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 ( ) const

returns read-write reference to the current sparse matrix element
