Re: [Boost-users] Property map deletion

Hi Jeremy, Internal. Here is my implementation. It is right out of your (very helpful) book. -d namespace boost { // ECInGraph custom properties. enum vertex_com_t {vertex_com = 1223497}; enum edge_nEmailsIn_t {edge_nEmailsIn = 1223498}; enum edge_nEmailsOut_t {edge_nEmailsOut = 1223499}; enum edge_sourceVD_t {edge_sourceVD = 1223500}; BOOST_INSTALL_PROPERTY (vertex, com); BOOST_INSTALL_PROPERTY (edge, nEmailsIn); BOOST_INSTALL_PROPERTY (edge, nEmailsOut); BOOST_INSTALL_PROPERTY (edge, sourceVD); } typedef boost::property > > InGraphEdgeProps; typedef boost::property > InGraphVertexProps; typedef boost::adjacency_list < boost::vecS, // Edge list is a std::vector boost::vecS, // Vertex list is a std::vector boost::undirectedS, // undirected graph InGraphVertexProps, // Vertex properties InGraphEdgeProps, // Edge properties boost::no_property // Graph properties > ECInGraph; void EC::InitGraphPropertyMaps() { // m_inGraph property maps. m_g2VName = boost::get(boost::vertex_name, m_inGraph); m_g2Com = boost::get(boost::vertex_com, m_inGraph); m_g2EmailsIn = boost::get(boost::edge_nEmailsIn, m_inGraph); m_g2EmailsOut = boost::get(boost::edge_nEmailsOut, m_inGraph); m_g2SourceVD = boost::get(boost::edge_sourceVD, m_inGraph); } Jeremy Siek wrote:

I'm not sure what you mean by "custom". Are you using an internal property map (e.g., inside an adjacency_list) or are you using some external property map?
