Do you have to use the property map method? I've converted over to bundled properties. Much simpler and intuitive. http://www.boost.org/libs/graph/doc/bundles.html -----Original Message----- From: Christian Sturz [mailto:linuxkaffee@gmx.net] Sent: Friday, February 15, 2008 1:01 AM To: boost-users@lists.boost.org Subject: [Boost-users] Pointers as graph vertex property Hi, I've a question about Boost Library Graphs. My Boost Graph is defined as: typedef boost::adjacency_list< boost::vecS, boost::vecS, boost::directedS, boost::property< boost::graph_name_t, std::string >, boost::property< boost::vertex_index_t, ClassA* > > Boost_Graph; So, I want to have a pointer to an entity of class ClassA as vertex property "vertex_index". However, when I try to access this property via a property map boost::property_map< Boost_Graph, boost::vertex_index_t >::type vertexNameMap = get( boost::vertex_index, g ); with vertexNameMap[v] (where v is Vertex_Type) the compiler tells me that the property is not of type 'ClassA*' (as I would expect) but of type 'size_t'. Why? I thought that for the definition of boost::property< boost::vertex_index_t, ClassA* > ClassA* is the template value and defines the type of the property "vertex_index". Any ideas how I can manage it to store pointers as vertex property? Regards, Christian -- Psst!
