Iterating through edges with custom defined edge properties of boost::adjacency_list

I'm working on a simulation program which uses boost::adjacency_list to represent a graph. The edges have costume designed properties

struct edge_data{
    const float linear_cost, const_cost;
    std::queue<*Agent> agents;

    edge_data(float lin, float con) : linear_cost(lin),const_cost(con) {}
};

After trying several ways, I haven't found a way to create a property_map which returns the full EdgeData for each edge, or any other way to iterate through and modify edges. Is it possible, and if so, how?

You ask the edge bundle from the graph, either

• using the boost::edge_bundle_t property map:

  auto pmap = boost::get(boost::edge_bundle, my_graph);
  edge_data& data = pmap[my_edge_descriptor];
  

• using the convenience accessors:

  edge_data& data = mygraph[my_edge_descriptor];
  

• or using specific property maps for a sub-property:

  auto costmap = boost::get(&edge_data::linear_cost, my_graph);
  float cost = costmap[my_edge_descriptor];
