Hi!
I am using Query / LocalQuery to loop through the results from a query. For several reasons it would be nice to know the number of hits before/without looping through the results.
Is this possible?
Kind regards Ketill Fenne

Hi Ketill,
If you want, you can check out the Query and LocalQuery code and add a function, which returns the value of cache.size(). If it works out for you, we may add it to the offiicial API.
Hope this helps, Christian

Hello,
As a matter of fact I just did exactly that. I didn't modify directly LocalQuery class though, but added two subclasses of LocalQuery and LocalSession.
Seems to work pretty well.
Regards
Simon
Here is the code, if you are interested.
