Detailed Description

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

This class can read paths from files. You can store paths in distinict mapset or in attributes section.

      GraphReader<SmartGraph> gr(std::cout, g);
      NodeMapReader<SmartGraph> nmr(gr, g, gr);
     
      SmartGraph::NodeMap<Path<SmartGraph> > pnm(g);
      nmr.readNodeMap("pnm", pnm, PathReader<Path<SmartGraph> >(gr));
     
      gr.run();

Warning:

Do not use this class to read node or edge map values from nodesets or edgesets. The edges are not surely constructed when the edge list should be read. Rather use NodeMapReader, EdgeSetReader or UEdgeSetReader to read distinict map sets from file.
