Undirector< DGR > Class Template Reference

Detailed Description

template<typename DGR>
class lemon::Undirector< DGR >

Undirector adaptor can be used for viewing a digraph as an undirected graph. All arcs of the underlying digraph are showed in the adaptor as an edge (and also as a pair of arcs, of course). This adaptor conforms to the Graph concept.

The adapted digraph can also be modified through this adaptor by adding or removing nodes or edges, unless the GR template parameter is set to be const.

This class provides item counting in the same time as the adapted digraph structure.

Template Parameters:
DGRThe type of the adapted digraph. It must conform to the Digraph concept. It can also be specified to be const.
The Node type of this adaptor and the adapted digraph are convertible to each other, moreover the Edge type of the adaptor and the Arc type of the adapted digraph are also convertible to each other. (Thus the Arc type of the adaptor is convertible to the Arc type of the adapted digraph.)
