[Boost-users] dynamic_properties and std::vector attributes

Subject: [Boost-users] dynamic_properties and std::vector attributes

Hi guys,

the boost graph library has an example on using bundled properties. I
would like to serialise the resulting graph into graphml. Using
dynamic_properties for the std::vector attribute fails to compile with
boost 1.41. Is there a way to get this example below to work? I would
greatly appreciate it.

Thanks,
Dominik

#include <vector>
#include <string>

#include <boost/graph/adjacency_list.hpp>
#include <boost/property_map/dynamic_property_map.hpp>

struct City
{
    std::string name;
    int population;
    std::vector<int> zipcodes;
};

struct Highway
{
    std::string name;
    double miles;
    int speed_limit;
    int lanes;
    bool divided;
};

int main()
{
    typedef boost::adjacency_list<
        boost::listS, boost::vecS, boost::bidirectionalS,
        City, Highway> Graph;

    Graph g;
    Graph::vertex_descriptor v = *vertices(g).first;
    g[v].name = "Troy";
    g[v].population = 49170;
    g[v].zipcodes.push_back(12180);
    Graph::edge_descriptor e = *out_edges(v, g).first;
    g[e].name = "I-87";
    g[e].miles = 10;
    g[e].speed_limit = 65;
    g[e].lanes = 4;
    g[e].divided = true;

    boost::dynamic_properties dp;
//    dp.property("zip_codes", boost::get(&City::zipcodes, g));
    dp.property("name", boost::get(&City::name, g));

    return EXIT_SUCCESS;
}
