You can use filtered_graph to filter both edges and vertexes:

filtered_graph<Graph, EdgePredicate, VertexPredicate>

You just have to pass to function objects, as in here:

https://svn.boost.org/trac/boost/attachment/ticket/11838

https://svn.boost.org/trac/boost/attachment/ticket/11838/yen_ksp.hpp

If your function objects need more information, you can pass it to the 
constructors of the function objects.

Best,
Irek
