Re: boost::filtered_graph filtering on vertex color... if I only had a colormap

Hello, everybody,
I have followed your conversation and since I have a similar problem, I
would be happy if you could help me. At the moment I am really lost. 

The problem is to create the color map that can be used in
Depth_First_Search. A special feature that I have is that I want to change
the Vertex color of DFS to modify the DFS. For example like this:

If I make the color map global and pass it to the visitor, everything works:

If the color map is not global but external, I can write the map, but it is
not the same as the DFS color map and therefore I cannot manipulate the DFS
algorithm:

I then tried to create an internal map and work with the get() and put()
functions, but I didn't succeed:

I'd be so grateful for any hint.

Best
Juergen
