<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">This isn't really ref counting.
It will say how many of this type of object are in the system, not count how many pointers there are to this one instance. (actual ref counting)
Anyway, I'd be very surprised if plasma worked this way. I'm pretty sure if an other plasmoid starts using it, it will increase the ref count of the dataengine and NOT call the constructor again.
I would suggest looking where the parent class has it's ref counter increased.
(arguably this will work to tell if the dataengine exists or not.. which is probably actually all that's needed in reality.)
tl;dr pretty sure this won't work. Happy to be proved wrong if you have evidence otherwise.

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">You're right about the refCount, it is not an actual refCount as that variable was initially used for refCount and then I changed it to static var, but left the name like this. In the end it doesn't really matter, it works as it should, really ;) It works in such way, that the dbus interface exposes a method for returning this refCount var (whatever it really is) only if the dataengine is created, when the dataengine is not in use (ie. deleted), the dbus method does not exist, so in the end it serves its purpose. I can change the variable to something like int isActive, but I think it's enough for a temp workaround.</pre>

Actually - why have this variable at all?
If you get a dbus response it's active. If you don't - and get a dbus error, then it isn't.
You may even simply be able to see if the dbus address exists and not need any methods in the address at all.

Next part will be checking from contact list for this dbus entry/method. It is meant as a temp workaround for bug 270675, once the upstream has proper features, we will remove it.</pre>
