Hello list members,

I've a little question:

Is it possible and if so, how is it possible, to randomly access a vertex or edge by its id (according to vertex_index or edge_index proprty map)?, i.e. calling 'vertices(graph)[id]'.

My problem is that I wan't to access a vertex or edge in an unique and graph lifespan-wide manner without iterate over all vertices or edges. With vertex_descriptor/edge_discriptor it's possible but only if I don't change the graph structur (not lifespan-wide).

Kind regrads,
Manuel
