Detailed Description
template<typename value_type>
class bolt::cl::constant_iterator< value_type >
constant_iterator iterates a range with a constant value.
The following demonstrates how to use a constant_iterator.
#include <bolt/cl/constant_iterator.h>
#include <bolt/cl/transform.h>
...
std::vector<int> vecSrc( 5 );
std::vector<int> vecDest( 5 );
std::fill( vecSrc.begin( ), vecSrc.end( ), 10 );
bolt::cl::control ctrl = control::getDefault( );
...
bolt::cl::constant_iterator< int > const5( 5 );
bolt::cl::transform( ctrl, vecSrc.begin( ), vecSrc.end( ), const5, vecDest.begin( ), bolt::cl::plus< int >( ) );
// vecDest is vector filled with the value 15, the sum of vecSrc and the constant value 5 from the iterator
// constant_iterator can save bandwidth when used instead of a range of values.
The documentation for this class was generated from the following file:
