Hi, I am fairly new to boost and I have a problem using the in_edges(v, G) function. I have defined a graph of type AdjacencyList: typedef adjacency_list< vecS, vecS, directedS, VertexProperties, EdgeProperties
mcf_graph;
The following code with m_current_network being a private class variable of type mcf_graph void best_insertion::search() { vertex_descriptor v,u,w; edge_descriptor e; graph_traits<mcf_graph>::in_edge_iterator in_e, in_end; graph_traits<mcf_graph>::out_edge_iterator out_e, out_end; edge_index_map_t edge_indices=get ( edge_index, m_current_network ); edge_type_map_t edge_types= get(edge_type, m_current_network); capacity_map_t edge_capacities=get ( edge_capacity, m_current_network ); vector<int> indices; vector<int>::iterator it, it_end; //select vertex v to reinsert //find_edge_indices of vertex v for ( tie ( in_e, in_end ) = in_edges(v, m_current_network ); in_e != in_end; in_e++ ) { e=*in_e; indices.push_back ( edge_indices[e] ); } for ( tie ( out_e, out_end ) = out_edges( v, m_current_network ); out_e != out_end; out_e++ ) { e=*out_e; indices.push_back ( edge_indices[e] ); } produces the error: error: no matching function for call to 'in_edges(vertex_descriptor&, mcf_graph&)' The problem does not occur for out_edges. From the examples I have seen AdjacencyList should support both functions. Can anybody explain to me why in_edges do not work for this example? -- Best Regards, Berit Løfstedt PhD.
