Subject [jira] Commented: (DERBY-815) Prevent unneeded object creation and excessive decoding in parseSQLDTA_work()
Date Tue, 08 Aug 2006 18:32:14 GMT
    [ 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").
