I'd like to get the size of the list that is returned by cursor.fetchall().  I tried various things but didn't succeed.  What should I be using?

It's not clear to me if this list is an actual Java class.  If it is, could somebody tell me where I could find the javadoc for it and the whole API to which it belongs.  Or, if it's some Jython thing, could somebody point me to best API-type documentation for it?

Thanks for any help
