Subject [jira] [Created] (COLLECTIONS-433) TreeList.addAll() complexity
Date Thu, 06 Sep 2012 15:19:07 GMT
Adrian Nistor created COLLECTIONS-433:
-----------------------------------------

             Summary: TreeList.addAll() complexity
                 Key: COLLECTIONS-433
                 URL: https://issues.apache.org/jira/browse/COLLECTIONS-433
             Project: Commons Collections
          Issue Type: Bug
    Affects Versions: 3.2.1
            Reporter: Adrian Nistor


"TreeList.addAll(Collection coll)" has a higher complexity than
necessary when "coll" is a "TreeList" object (because "addAll" just
adds one element at a time).  This can be done in just O(N) as
described for example here:

Are there any plans to improve this?
