[Boost-users] [BGL] Simple question about accessing vertex property

Hi,

How do I access the vertex_index property of a vertex? Is it necessary 
to use the get function? More precisaly, let us consider the following:

typedef adjacency_list<vecS, vecS, bidirectionalS,
                         no_property, property<edge_weight_t, int> > TGraph;

typedef graph_traits<TGraph>::vertex_descriptor TNode;

Suppose that 'vertex' is a TNode. Is it correct to do

int idx = vertex;

to get in idx the vertex_index of vertex?

Thanks in adavnce,
Giulio
