[Boost-users] BGL adjacency_list bundled properties io

20 Mar 2007

      I am trying to use an adjacency list with bundled properties.

So I type my graph data stucture as so:

struct MyV {
    int numOnVertex;
};

struct MyE {
    int numOnEdge;
};

typedef  adjacency_list<setS, setS, bidirectionalS, MyV, MyE>  MyGraph;

I would like to use the read function as defined in 
adjacency_list_io.hpp, so I can read in my special graph from a file 
that looks like below.
# 3 vertices, v0.numOnVertex=6, v1.numOnVertex=5, v2.numOnVertex=3
v
0 6
1 5
2 3

# 3 edges, edge 0, numOnEdge=0; edge 1, numOnEdge=3, edge 2, numOnEdge = 3
e
1 2 0
0 1 3
1 0 3

I can't seem to figure out a simple way to do IO with bundled properties. 

When I try these lines:
    MyGraph g;
    cin >> read(g);

I get the error:
C:\boost_1_33_1\boost/graph/adjacency_list_io.hpp(153) : error C2679: 
binary '>>' : no operator found which takes a right-hand operand of type 
'MyV' (or there is no acceptable conversion)
