Stephen Allen commented on JENA-26:
-----------------------------------
There is no other way to find out the count of a find pattern in a standard way
through Jena. Some graph store implementations *might* be able to answer that
question without iterating over all the results. However, stores that retain
this information typically do so for query optimization, therefore it would
usually just be an estimate for costing purposes and not necessarily accurate.
And finally, even if there were a store that had an accurate answer there is no
current way to expose that through the standard Graph interface, so retrieving
it would be implementation specific.
