Read-Only Sparse Matrix Iterator.
Here is how to use the iterator to compute the sum of floating-point sparse matrix elements:
cv::SparseMatConstIterator::SparseMatConstIterator | ( | ) |
the default constructor
cv::SparseMatConstIterator::SparseMatConstIterator | ( | const SparseMat * | _m | ) |
the full constructor setting the iterator to the first sparse matrix element
cv::SparseMatConstIterator::SparseMatConstIterator | ( | const SparseMatConstIterator & | it | ) |
the copy constructor
const SparseMat::Node* cv::SparseMatConstIterator::node | ( | ) | const |
returns the current node of the sparse matrix. it.node->idx is the current element index
SparseMatConstIterator& cv::SparseMatConstIterator::operator++ | ( | ) |
moves iterator to the next element
SparseMatConstIterator cv::SparseMatConstIterator::operator++ | ( | int | ) |
moves iterator to the next element
SparseMatConstIterator& cv::SparseMatConstIterator::operator-- | ( | ) |
moves iterator to the previous element
SparseMatConstIterator cv::SparseMatConstIterator::operator-- | ( | int | ) |
moves iterator to the previous element
SparseMatConstIterator& cv::SparseMatConstIterator::operator= | ( | const SparseMatConstIterator & | it | ) |
the assignment operator
void cv::SparseMatConstIterator::seekEnd | ( | ) |
moves iterator to the element after the last element
