添加一个外部属性以包含图中vertix的索引(boost)

我试图使用associative_property_map来包含顶点的索引,但是我用下面的简单代码得到以下错误,问题是什么?

#include <boost/graph/iteration_macros.hpp>
#include <boost/graph/adjacency_list.hpp>

using namespace std;
using namespace boost;

struct NodeData
{
    int label;
};

struct EdgeData
{
    int age;
};

typedef map<vecS, size_t> IndexMap;
IndexMap mapIndex;
associative_property_map<IndexMap> propmapIndex(mapIndex);

typedef adjacency_list<setS, setS, undirectedS, NodeData, EdgeData> Graph;
typedef Graph::vertex_descriptor NodeID;
typedef Graph::edge_descriptor EdgeID;

int main()
{
    Graph g;

    NodeID n0 = add_vertex(g); g[n0].label = -1;
    NodeID n1 = add_vertex(g); g[n1].label = -1;

    EdgeID edge; bool ok;
    tie(edge, ok) = boost::add_edge(n0, n1, g);
    if (ok) g[edge].age = 10;

    int i=0;
    BGL_FORALL_VERTICES(v, g, Graph)
    {
        put(propmapIndex, v, i++);
    }

    return 0;
}

错误:

谢谢


顶点描述符必须指定给IndexMap,因此它的map<NodeID, size_t>而不是map<vecS, size_t>

<...>
typedef Graph::vertex_descriptor NodeID;

typedef map<NodeID, size_t> IndexMap;
IndexMap mapIndex;
associative_property_map<IndexMap> propmapIndex(mapIndex);
<...>

// indexing all vertices
int i=0;
BGL_FORALL_VERTICES(v, g, Graph)
{
   put(propmapIndex, v, i++);
}
