Detailed Description

This class is an Lp variable item writer for Lemon IO. It makes possible to store lp variables in lemon file. The usage of this class is very simple:

      Graph graph;
      Lp lp;
      Graph::EdgeMap<Lp::Col> var(graph); 
     
      GraphWriter<Graph> writer(cin, graph);
      writer.writeEdgeMap("lpvar", var, LpColWriter(lp));
      writer.run();

If there is no name associated to the current item then the name will automatically constructed. If the value is INVALID then it will write an '-' value to the file. #include <lemon/lp_utils.h>
