Subject [jira] [Commented] (CASSANDRA-8988) Optimise IntervalTree
Date Mon, 23 Mar 2015 12:24:18 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-8988?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14375790#comment-14375790

Branimir Lambov commented on CASSANDRA-8988:
--------------------------------------------

bq. the argument Op makes it quite clear what you're asking for

Agreed, let's use binarySearchAsymmetric.

bq. By convention i <= j in algorithms

I don't think this is a widely used convention, it is probably very clear to you but isn't
to me. lb/ub sounds good.

bq. strictnessOfLessThan

Sounds good.
