You can find <a href="http://www.boost.org/doc/libs/1_51_0/boost/graph/isomorphism.hpp" rel="nofollow">here</a> the definition of <code>degree_vertex_invariant</code>. It's simply a function object with typedefs for <code>result_type</code> and <code>argument_type</code> that is expected to be called with each of the vertices of the graph and that also has a member called <code>max</code> that return an integer equal to the max value of your invariants plus one. A similar functor using your <code>discrete_vertex_invariant</code> function would look like this: <pre><code>template <typename Graph> class discrete_vertex_invariant_functor { typedef typename boost::graph_traits<Graph>::vertex_descriptor vertex_t; const Graph &graph; public: typedef unsigned int result_type; typedef vertex_t argument_type; discrete_vertex_invariant_functor(const Graph &g):graph(g){} result_type operator()(argument_type v)const { return discrete_vertex_invariant(v,graph); } result_type max() { return MAX_LABEL+1; } }; //helper function to help with argument deduction template <typename Graph> discrete_vertex_invariant_functor<Graph> make_discrete_vertex_invariant(const Graph &g) { return discrete_vertex_invariant_functor<Graph>(g); } </code></pre> You could then invoke <code>isomorphism</code> using its named-parameter version: <pre><code>bool ret=isomorphism(g1, g2, isomorphism_map(make_iterator_property_map(f.begin(), v1_index_map, f[0])) .vertex_invariant1(make_discrete_vertex_invariant(g1)) .vertex_invariant2(make_discrete_vertex_invariant(g2)) ); </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
