[jira] Commented: (DERBY-815) Prevent unneeded object creation and
excessive decoding in parseSQLDTA_work()
[ http://issues.apache.org/jira/browse/DERBY-815?page=comments#action_12426672 ]
Dyre Tjeldvoll commented on DERBY-815:
--------------------------------------
No I don't see this as urgent for 10.2. Wrt. to the visibility of CliParam in DRDAConnThread, I think you're making a valid point. However, CliParam was not added to improve encapsulation or code structure. It is just a utility to avoid having two containers of (pointers to) Integer/Long objects that were created and discarded again and again. I actually tried to preserve the existing program structure as much as possible, ("small incremental changes").
