HeapUnionFind< V, IM, Comp >::ItemIt Class Reference

Detailed Description

template<typename V, typename IM, typename Comp = std::less<V>>
class lemon::HeapUnionFind< V, IM, Comp >::ItemIt

ClassIt is a lemon style iterator for the components. It iterates on the items of a class. By example if you want to iterate on each items of each classes then you may write the next code.

for (ClassIt cit(huf); cit != INVALID; ++cit) {
  std::cout << "Class: ";
  for (ItemIt iit(huf, cit); iit != INVALID; ++iit) {
    std::cout << toString(iit) << ' ' << std::endl;
  }
  std::cout << std::endl;
}
