Subject Re: [collections] Implementation of List with a tree
Date Tue, 03 Feb 2004 22:14:05 GMT
Sounds interesting. See
http://jakarta.apache.org/commons/patches.html

Also see Bugzilla for an AVLTree/Set already proposed. (You may want to
reuse this in some way)
http://issues.apache.org/bugzilla/show_bug.cgi?id=22853

What I really need is a good implementation with tests written using the
collections testframework. Plus a reason for including it. (Performance
between Array and Linked is a good reason ;-)

Finally, you must declare that your submission is donated to the Apache
Software Foundation.
