[Boost-users] Dijkstra Visitor - Accessing the priority queue

From: Jonas Gabriel (gkamprie_at_[hidden])

Good morning,

I'm trying to make a single pair shortest path function using the 
goal-directed search technique  based on dijkstra_shortest_paths and 
Visitors.

In some point when the target vertex is processed, I would like to exit 
dijkstra_shortest_paths.To do that I 'm thinking trying to empty the 
priority queue.

Can I access the priority queue inside a visitor using something like an 
extern declaration, since none of the Dijkstra Visitor's methods gets 
the priority queue as an argument ?

With regards,
Jonas Gabriel
