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 The online docs for PropertyGraph and MutablePropertyGraph look a bit out of date, and need to be sync'd with the graph_concepts.hpp.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 On Mar 14, 2004, at 7:00 PM, Douglas Gregor wrote:
Is this possible? A well-defined return type from get(p, g) when p is not an internal property of graph g would suffice.
