Detailed Description

template<typename Path>
class lemon::PathWriter< Path >

This class can write paths into files. You can store paths in distinict mapset or in attributes section.

      GraphWriter<SmartGraph> gw(std::cout, g);
      NodeMapWriter<SmartGraph> nmw(gw, g, gw);
     
      SmartGraph::NodeMap<Path<SmartGraph> > pnm(g);
      for (SmartGraph::NodeIt n(g); n != INVALID; ++n) {
        pnm[n] = bfs.path(n);
      }
      nmw.writeNodeMap("pnm", pnm, PathWriter<Path<SmartGraph> >(gw));
     
      gw.run();

Warning:

Do not use this class to write node or edge map values into usual nodesets or edgesets. You will not be able to read back your paths. Rather use NodeMapWriter, EdgeSetWriter or UEdgeSetWriter to dump paths from maps to lemon file.
