The UDSEntry struct is in the Smoke runtime, I not sure about lists of them. 
It might need a custom marshaller to do that, I'll have a look. I left 
UDSEntry out of the current koala java api because they seemed too low level 
- perhaps that was wrong.

Well, that's an interesting use for them. I tend to use the kde javadoc 
documentation to read about the kde api, because I think it looks/reads 
better than the C++ original.
