I scanned the README, and there's no mention of the python-side name remapping. Is it only possible to discover the python-side names (so that one can override a specific java method in an overloaded set) by looking at the .cpp files? > Andi just checked in the SimilarityDelegator method, which > sounds like what you want: see > http://lists.osafoundation.org/pipermail/pylucene-dev/2007-Mar > ch/001595.html > > Hope this helps. > > Aaron Lav (http://www.pobox.com/~asl2) Looks like someone was asking almost the same question is me just a week before. :) Props to Andi for getting that fix in so soon. I'll wait for the next minor version release, though - makes life a little simpler. Besides, not having the Delegator class available to me has forced me to better understand the art of extending PyLucene. -ofer _______________________________________________ pylucene-dev mailing list [email protected] http://lists.osafoundation.org/mailman/listinfo/pylucene-dev
