Class template permutation_iterator

boost::compute::permutation_iterator — The permutation_iterator class provides a permuation iterator.

Synopsis

// In header: <boost/compute/iterator/permutation_iterator.hpp>
template<typename ElementIterator, typename IndexIterator> 
class permutation_iterator {
public:
  // types
  typedef unspecified                 super_type;     
  typedef super_type::value_type      value_type;     
  typedef super_type::reference       reference;      
  typedef super_type::base_type       base_type;      
  typedef super_type::difference_type difference_type;
  typedef IndexIterator               index_iterator; 
  // construct/copy/destruct
  permutation_iterator(ElementIterator, IndexIterator);

};

Description

Итератор перестановок повторяется в диапазоне значений и в диапазоне индексов. При отмене он возвращает значение из диапазона значений, используя текущий индекс из диапазона индексов.

Например, для изменения диапазона с помощью алгоритма копирования() и последовательности перестановок:
