Re: [Boost-users] [BGL] Determining if a graph has a particular internal property?

Hi Doug,

There's the vertex_property<Graph>::type and edge_property<Graph>::type
meta-functions which return the property list. You can then
use the property_value meta-function on the result, and if that
returns error_property_not_found, you know it is not there.

The online docs for PropertyGraph and MutablePropertyGraph look a bit
out of date, and need to be sync'd with the graph_concepts.hpp.

Cheers,
Jeremy
