Dear all,
I am using bundled properties when I define my graph.
The bundled properties are smart pointers to my own class Edge and Vertex.
I write something like:
typedef boost::shared_ptr<Vertex> VertexPtr;
typedef boost::shared_ptr<Edge> EdgePtr;
typedef adjacency_list Graph;
Vertex and Edge being my own classes to store information on the
vertices and the edges.
For what I read in the doc, this is the correct, more modern way to do it.
My problem is the following.
I am trying to use the BGL algorithms and some of them require
vertex/edge info to be provide as properties maps.
From http://www.boost.org/doc/libs/1_41_0/libs/graph/doc/bundles.html
I know it is possible to generate those maps from bundled properties.
It works well if I don't use shared_ptr but cannot compile otherwise.
When using shared_ptr, similarly to the doc, I wrote:
typedef property_map::type WeightMap;
WeightMap weightMap = get(&EdgePtr::m_cost, *_graph);
m_cost being a public float member of my own class Edge.
I have the following compilation error:
'm_cost' : is not a member of 'boost::shared_ptr<T>'
Indeed it is not.
My question is, I can let the shared_ptr access the member?
In other world how to deal with bundled properties / properties maps and
shared_ptr.
Extra question, could 'm_cost' be a private member of my own class Edge?
Thank you very much
Sincerely,
Damien
