Hi,
I have a mutable property undirected graph. I want to delete all the vertices and edges in the graph.
I tried using the for loop
for( b = *vertices( databaseGraph ).first; b!= *vertices( databaseGraph ).second; b++ ){ clear_vertex( b, databaseGraph ); remove_vertex( b, databaseGraph ); }
The major problem here is that you shouldn't be dereferencing vertices(databaseGraph).second, because it is a past-the-end iterator. You could rewrite the loop as: while (vertices(databaseGraph).first != vertices(databaseGraph).second) { b = *vertices(databaseGraph).first; clear_vertex(b, databaseGraph); remove_vertex(b, databaseGraph); }
Can you let me know what is the correct way of deleting all edges and vertices in a mutable property undirected graph.
The easy way is just "databaseGraph.clear()" Doug
