[Lemon-user] Using filterNodes with bpGraphCopy?

[Noam Goldberg]

Hi,

I am trying to use filterNodes within bpGraphCopy:

bpGraphCopy(filterNodes(_graph, nf), g).nodeRef(nr).run();

(Here both graphs are of type SmartBpGraph),

but I then get a compilation error such as:

/lemon-main/lemon/core.h:1184:36: error: no type named ‘RedNode’ in ‘class
lemon::FilterNodes<const lemon::SmartBpGraph,
lemon::BpGraphExtender<lemon::SmartBpGraphBase>::NodeMap<bool>, void>’

I could not find a special FilterNodes (sub)class for bipartite graphs.
How should I otherwise go about copying a subgraph of a BpGraph ? (I might
also need to copy a RedNodeMap and/or BlueNodeMap).

Thank you in advance,
Noam
