One issue and one possible improvement, in my opinion. Currently, when parentUdi is set and type is Unknown, all the children are returned. In your patch, none of the children are returned, unless the last routine in queryDeviceInterface() returns true with Unknown type, but I doubt it as it's optimised for types like Generic, etc., but not for Unknown. Anyway, it's a case we should optimise here. Should we think that the current behaviour is wrong, then why is allDevices() returned when both parentUdi and type aren't specified? About the improvement, I'm speaking of removing duplication. The first two checks are mostly equal, they could be condensed into one (tweaking the if() inside the foreach()), with "return allDevices()" being moved on top if (parentUdi.isEmpty() and type == Unknown). - Alberto Villa On July 19, 2012, 2:17 a.m., Raphael Kubo da Costa wrote: > > ----------------------------------------------------------- > This is an automatically generated e-mail.
