I'd like to use the graph library to support connections between
different types of objects.
To do this I've created a class GraphNode that forms the base class for
various other objects
that can become vertices of the graph. I've tried the following.
int main(int,char*[])
{
//these two classes Translate and Mesh inherit from GraphNode
Translate* pT = new Translate;
Mesh* pM = new Mesh;
// create a typedef for the Graph type
typedef adjacency_list Graph;
const int num_vertices = 2;
// writing out the edges in the graph
typedef std::pair GraphEdge;
GraphEdge edge_array[] =
{ GraphEdge(pT,pM) };
const int num_edges = sizeof(edge_array)/sizeof(edge_array[0]);
// declare a graph object
Graph g(num_vertices);
// add the edges to the graph object
for (int i = 0; i < num_edges; ++i)
add_edge(edge_array[i].first, edge_array[i].second, g);
return 0;
}
but get the following error message related to the fact that it can't choose a suitable overloaded add_edge function. If I replace the types in the vertex with an int it compiles happily. I'm using Boost 1.30.0
