Undirector< DGR >::CombinedArcMap< FW, BK > Class Template Reference

Detailed Description

template<typename DGR>
template<typename FW, typename BK>
class lemon::Undirector< DGR >::CombinedArcMap< FW, BK >

This map adaptor class adapts two arc maps of the underlying digraph to get an arc map of the undirected graph. Its value type is inherited from the first arc map type (FW).

Template Parameters

FW	The type of the "foward" arc map.
BK	The type of the "backward" arc map.
