[−][src]Trait opencv::hub_prelude::SparseMatConstIteratorTrait
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
Required methods
pub fn as_raw_SparseMatConstIterator(&self) -> *const c_void
[src]
pub fn as_raw_mut_SparseMatConstIterator(&mut self) -> *mut c_void
[src]
Provided methods
pub fn m(&self) -> SparseMat
[src]
pub fn hashidx(&self) -> size_t
[src]
pub fn set_hashidx(&mut self, val: size_t)
[src]
pub fn ptr(&mut self) -> &mut u8
[src]
pub fn set_ptr(&mut self, val: &mut u8)
[src]
pub fn node(&self) -> Result<SparseMat_Node>
[src]
returns the current node of the sparse matrix. it.node->idx is the current element index
pub fn seek_end(&mut self) -> Result<()>
[src]
moves iterator to the element after the last element
