GraphWriter< GR > Class Template Reference

Detailed Description

template<typename GR>
class lemon::GraphWriter< GR >

This utility writes an LGF file.

It can be used almost the same way as DigraphWriter. The only difference is that this class can handle edges and edge maps as well as arcs and arc maps.

The arc maps are written into the file as two columns, the caption of the columns are the name of the map prefixed with '+' and '-'. The arcs are written into the @attributes section as a '+' or a '-' prefix (depends on the direction of the arc) and the label of corresponding edge.
