Extract C++ edge from graph_tool.libgraph_tool_core.Edge

graph-tool

Hi,

I'm using graph-tool from both Python and C++. Normally, all works well
with the dispatch function. But now I came to a situation, where I get
an edge object (graph_tool.libgraph_tool_core.Edge) and want to use
this from C++. Is there a way to do this?

This is the same question as: I have a function `void do_stuff(PyObject* foo)`
where `foo` is a `graph_tool.libgraph_tool_core.Edge`. Can I extract the
boost::detail::adj_edge_descriptor somehow (or whatever is the correct
edge type)?

Kind regards
Gerion

Found out by myself. It is actually fairly simple.

void extract_edge(PyObject* py_edge) {
    graph_tool::EdgeBase& edge_base = boost::python::extract<graph_tool::EdgeBase&>(py_edge);
    graph_tool::GraphInterface::edge_t edge = edge_base.get_descriptor());
}

Best,
Gerion
