Sorry for being unclear. I mean that if I find 'make_label_writer' call in C++ code, I don't know where to look for documentation. There's no single list of all functions with links to documentation, ala "namespace members" in doxygen documentation.
Ahh. Yes, we do need an index.
So is your problem with external property maps, or with some graphs that don't provide a vertex index property?
The problem is that if a graph don't privde vertex index property, then it's not possible to create efficient external property map -- the only way I know is std::map, which is not as fast as property maps which use indices.
Is there some reason you want to have a graph without a vertex index property and also use external property maps? If not, just use graph a with a vertex index internal property. Or am I missing something?
Ah, but the documentation does not say that std::string is convertible to property<vertex_name_t,std::string>("brother"), at least I can't find it.
Oops, there's lots of stuff missing from the docs for property. I've checked in a bunch of additions.
Also, what happens if vertex_propety is
property<vertex_name_t, std::string, property<vertex_index_t, unsigned> >
will conversion from std::string or property<vertex_name_t, std::string> work?
Nope. See the new docs.
Probably, but we'd need to way to associate PropertyTag with each member. Another idea: isn't this a good application for named function parameters?
add_vertex(g, vertex_name_t("brother").vertex_index_t(10));
? I'm still in dark about named parameters used by BGL or the upcoming named param library, so is not sure if this exact syntax is implementable.
That's a good idea.
