No problem, this was all new to me once.

That last little step is done by dbus-glib, and I honestly don't know
how the internals works.

All I know is that if I call dbus_g_connection_register_g_object after
feeding it a .xml introspection file (look at Makefile.am) it converts a
dbus MethodNameLikeThis to a a function_name_like_this.

If you checkout the dbus-glib source code I'm sure it'll be interesting
reading -- I've never played much with the internals and so can't help
you much more, sorry.

Richard.
