Hi All ,
I've been trying to use a custom structure for describing the various edge
properties of a graph. I'm defining a graph as the following
struct edge_properties {
int capacity ;
double weight ;
typedef struct edge_properties_tag kind ; // NOT SURE what this does ?
};
typedef boost::adjacency_list,
edge_properties > Graph;
This allows me to create a Graph instance g. I've been trying to retrieve
the edge properties via a get call, but have not been able to do so.
To retrieve the vertex properties doing the following works
property_map::type v_names ;
v_names = get(vertex_name,g) ;
But on attempting to do something similar for retrieving the edge properties
always fails with the following error message
"test.cpp: 75: error: expected primary-expression before ',' token"
test.cpp
71: property_map::type epr;
72: property_map::type v_names ;
74: v_names = get(vertex_name,g) ;
75: epr = get(edge_properties,g) ;
I've tried various variants but seems to me i'm missing something
fundamental in the way boost-graph keeps the edge_properties hidden.
Any pointers will be useful.
Thanks in advance
