parent_iterator

I am a newbie to the graph library.

I have a directed graph, and given a vertex_descriptor, I would like to 
access its parents. It is sort of an adjacency_iterator in reverse I 
believe.

Is there such a thing, or do i have to derive it from and existing 
iterator...?

Thanks,

Matt
