[Boost-users] Creating a property map inside Dijkstra Visitor

Good afternoon, Inside a dijkstra visitor I would like to change the edge weights at some point, so in my visitor I'm trying to make a property map called weight :

template<class DynamicMap> class gds_visitor : public dijkstra_visitor<> { public:

gds_visitor(DynamicMap input):dynamic(input){}

....

template void examine_edge (Edge e, Graph& g) { typename property_map::type weight; weight=get(edge_weight, g);

std::cout << "An edge is being examined..." << "\n"; }

protected: DynamicMap dynamic; };

typedef adjacency_list

where Graph: property > Graph; and Edge:

typedef std::pair Edge;

But it is not compiling, mentioning a problem with weight 'soperator = . Thank you in advance, Jonas Gabriel
