[Lemon-user] GraphCopy : ??

[Mitcsenkov Attila]

Hi!

 

I tried to figure out how to make a duplicate of a (List)Graph object, but
now I give it up... :(

 

In the documentation I've found the GraphCopy class:

"Class to copy a graph to another graph (duplicate a graph). The simplest
way of using it is through the
<http://lemon.cs.elte.hu/pub/doc/latest/a00842.html#g44340894daf6f7d9908679c
fa989dab1> copyGraph() function."

 

OK. I've tried both, because the documentation about it was not so verbose.

 

Now this is the code that should work - if I understand the documentation.
Possibly not, because it doesn't work:

 

           lemon::copyGraph(LG,net.NetworkGraph);      // 1

           GraphCopy<ListGraph,ListGraph> GC(LG,net.NetworkGraph);
// 2

 

           for(ListGraph::NodeIt nIt(net.NetworkGraph);nIt != INVALID;
++nIt)

                      cout << "X" << endl;

           for(ListGraph::NodeIt nIt(LG);nIt != INVALID; ++nIt)

                      cout << "Y" << endl;

 

I've tried lines number  1 and 2 both separately, but none of them was
working: the output in any case was multiple X-s, and no Y-s.

 

 

Could you please help me, how to duplicate my graph?

 

Thanks:

Attila
