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;
*  }
*
