--- Comment #10 from Javen O'Neal <one...@apache.org> --- Created attachment 34241 --> https://bz.apache.org/bugzilla/attachment.cgi?id=34241&action=edit a non-working MapUniqueList class that mimicks an associative SetUniqueList If we can remove the scenario where duplicate entries may exist in the lists then we could write a MapUniqueList (see org.apache.commons.collections4.list.SetUniqueList), which may be more performant. Looking at the usage of these lists, we only use List.add(E), List.indexOf(E), and List.size(), so we may not run into the performance bottlenecks when elements in the array are shifted (and this makes sense--we wouldn't want to change the style index as there are other data structures that only reference the index, not the object itself. -- You are receiving this mail because: You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@poi.apache.org For additional commands, e-mail: dev-h...@poi.apache.org
