I have the following graph:
typedef property< vertex_index_t, uint32_t,
property< vertex_name_t, boost::shared_ptr<Component> > >
VertexProperty;
typedef adjacency_list // VertexProperties
Graph_Type;
When I looked at the documentation I did not see an example which used a
boost::shared_ptr to store information at the vertex. Here is my attempt
at writing a PropertyWriter. I cannot figure out how to write the 2nd
function argument type:
class Component_Writer {
public:
void operator()(std::ostream& out,
const boost::shared_ptr<Component> obj) const
{
out << "[label=\""
<< obj_ptr->get_Name()
<< "\n"
<< obj_ptr->get_ID()
<< "\"]";
}
};
The error I get is:
