Hi,
I would like to visit my graph in a particular order using a dfs visitor.
To do this I tried to order the out_edges of each node.

I use the std sort function, like this:
GraphContainer::out_edge_iterator oe_it, oe_itEnd;
boost::tie( oe_it, oe_itEnd ) = boost::out_edges( vd, graph );
std::sort( oe_it, oe_itEnd, OrderEdge<GraphContainer>(graph) );

But it does nothing. It seems that there is an empty operator= on out_edge_descriptor.
So, how can I sort the out_edges ?

Best regards,
