I am using the default depth_first_search visitor with an graph setup as
follows:
typedef property< vertex_index_t, uint32_t,
property< vertex_name_t,
boost::shared_ptr<Component> > >
VertexProperty;
typedef adjacency_list // VertexProperties
Graph_Type;
typedef graph_traits::vertex_descriptor
Vertex;
typedef graph_traits::edge_descriptor
Edge;
The graph contains Component class objects. I want to visit each
Component and execute the function run().
The test graph I have is a simple two node graph:
node A ---> node B
When I use the depth_first_search with my visitor I see that it only
visits node A. I do not know why this is the case. I have only
implemented the discover_vertex function in it. I have std::cout
messages for telling me various steps of run() have been done. I cannot
see how to have the visitor say what its doing (e.g. "I'm in node A.
Executing run(). Considering moving to node B).
What I need assistance on is how do I debug my visitor?
I am only sending the graph and the visitor to my call to
depth_first_search:
// Let Graph Visitor run through the Graph
// (visit Input graph)
depth_first_search (test_graph_ptr->get_Graph(),
visitor(vis));
