Hi,
I am new to LEDA and to C++.   I am running the  LEDA-R-3.3 package.

I am wondering if there is some supported way of modifying
an integer value that is part of the node info (what v->data[0] points to).

I have a GRAPH<my_node_info, my_edge_info> G.  After I finish
constructing the graph G, I would like to change the value of an
integer K that is a member of the class my_node_info.
Is there support for doing this?

I can't use a node_map or node_array because I would like to use the
sort_node() function based on the modified value of K.

Help would be greatly appreciated.
Thanks.

Soha

GRAPH<my_node_info,my_edge_info> G;
...
G[v].K = 17;
