Read-Only Sparse Matrix Iterator.

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

\code 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(); \endcode

Provided methods

fn m(&self) -> SparseMat[src]

fn hashidx(&self) -> size_t[src]

fn set_hashidx(&mut self, val: size_t)[src]

fn ptr(&mut self) -> &mut u8[src]

fn set_ptr(&mut self, val: &mut u8)[src]

fn node(&self) -> Result<SparseMat_Node>[src]

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

fn seek_end(&mut self) -> Result<()>[src]

moves iterator to the element after the last element
