[Boost-users] BGL - edge descriptor

Hi,

I'd like to extract the source and target vertex id from an 
edge_descriptor without using the graph that contains the edge. More 
specifically, consider the following code:

typedef graph_traits<MyGraph>::edge_descriptor MyLink;

void MyFunction(MyLink& link)
{
        cout << "source vertex id: " << ??? << ", target vertex id: " << ??? << 
endl;
}

What I've to put at place of ??? to print the source and target vertex 
id? Is it a dirty solution to use the m_source and m_target field of the 
edge_descriptor structure?

Thanks,
Giulio
