copied!<p>Below is code I used to attach some properties to vertices, edges, and graphs. Note that vertex name and graph name are predefined properties (see boost/properties.hpp for a complete list) so that <code>vertex_name_t</code> and <code>graph_name_t</code> are already defined. However, <code>vertex_location_t</code>, <code>edge_length_t</code>, and <code>graph_notes_t</code> are my own properties and hence need definition. I cobbled together this code from various examples and documentation, and I'm not sure exactly what <code>BOOST_INSTALL_PROPERTY</code> does, but the code seems to work fine.</p> <pre><code>// Define custom properties enum vertex_location_t { vertex_location }; enum edge_length_t { edge_length }; enum graph_notes_t { graph_notes }; namespace boost { BOOST_INSTALL_PROPERTY(vertex, location); BOOST_INSTALL_PROPERTY(edge, length ); BOOST_INSTALL_PROPERTY(graph, notes ); } // Define vertex properties: vertex name and location typedef property<vertex_name_t, string, property<vertex_location_t, Point3> > VertexProperties; // Define edge properties: length typedef property<edge_length_t, double> EdgeProperties; // Define graph properties: graph name and notes typedef property<graph_name_t, string, property<graph_notes_t, string> > GraphProperties; // Define a graph type typedef adjacency_list < vecS, // edge container type vecS, // vertex container type undirectedS, VertexProperties, EdgeProperties, GraphProperties > Graph; </code></pre>
