Hi to all,

I'm searching for a good method to stopping prematurely a graph 
exploration, e.g. when I've just founded and explored a particular vertex.

I think I've to create a visitor to which passing the particular vertex, 
but I don't know how to configure it.

A very brutal method is to wrap the exploration function in a try-catch 
block, and then throw an exception in the examine_vertex funtion. I want 
to believe that there's a more elegant method than this...

Best regards,
Cosimo Calabrese.
