Re: [Boost-users] [BGL] Is adjacency_iterator not Equality Comparable?

Please find a minimalist (but different) example in the attachments. I currently do know what's wrong but it's probably still better for my next question to attach the file. Consider the following line in my attached code:

iterator pos = find(begin, end, "3");

I know that this line doesn't compile because the value type of vertex iterator is not necessarily the same as VertexProperties. But, then, is there a simple way to find the vertex iterator that points to "3"? (I mean something as succinct as the above line of code. I DO already know that it's possible to pass an ugly function object to help find(). But, that's far too ugly.)

What about this (not tested)? typedef property::const_type pm_type; pm_type props(get(vertex_bundle, g)); typedef graph_traits::vertex_iterator v_iter_type; std::pair verts(vertices(g)); typedef property_map_iterator_generator::type iter_type; iter_type pos = find(make_property_map_iterator(props, verts.first), make_property_map_iterator(props, verts.second), "3"); v_iter_type pos_v = pos.base(); vertex_descriptor v = *pos_v; This needs to be included, plus all of the usual graph stuff. -- Jeremiah Willcock
