Hi Rodion,

sorry, but I stopped working on collections and it looks like nobody else
is interested either.

The datastructure seems interesting, I would propose to contribute it
either to guava or Eclipse Collections (descendent of GS collections).

[collections] An order statistic tree

Hello, all.
I would like to announce that I have a java.util.Set implementation that is an 
order statistic tree (all non-bulk operations + select + rank in O(log n) time) 
[1]. However, it seems like the team on behalf of the order statistic tree 
issue is rather idle [2], hence the message.
Best,

[collections] An order statistic tree (COLLECTIONS-479)

2016-02-13 Thread Rodion Efremov
I have revived some discussion at 
https://issues.apache.org/jira/browse/COLLECTIONS-479 
(https://issues.apache.org/jira/browse/COLLECTIONS-479)
Basically, what interfaces an order statistic tree should implement? What comes 
to the structure, will a counted AVL-tree do?
Best,
rodde
