<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">What's funny is that it looks fairly close from the code which would have to be written for the "smart device list" I discussed with Alex a couple of years ago. It'd have to be split in two and then the part independent from QML would need to be thread safe.
Note: I'm not asking you to do that, it's just for future reference.</pre>

The property should be named "empty" the getter is still named "isEmpty".</pre>

<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">revision 0:
This one will need more review and discussion - it exposes some of Solid functionality to QML.
The reason Solid classes are not exported directly is that they don't tend to have a no-arg constructor, and some of them are not QObjects.
It registers a class (org.kde.solid.)Devices (initially modelled after DeviceNotifier) that contains the following features:
- ability to list all devices or just those that match a defined query (Solid::Predicate)
- signals for when devices that match the query are added or deleted
- isEmpty property - are there no devices that match the query?
- count property - the number of devices that match the query
- devices property - a list of udis of the devices that match the query
- device method that returns a QObject interface to the device.
The things I'm in doubt about:
1. devices property and device(...) method are similarly named, while one gets udis, and the other actual DeviceInterface object.
Possible solutions:
- devices -> udis or deviceUdis
- device(...) -> deviceInterface(...) or something else
2. If the user creates two instances with the same query, both instances will contain a query and a Solid::Predicate, the query will be parsed two times and similar.
The implementation could be complicated a bit by creating private parts of instances with the same queries to be shared, but is it worth it?
