I need an IntervalTree or RangeTree implementation in Java, and am having trouble finding one with working deletion support.
There\'s a built-in one at sun.jvm.hotspot.u
I don't know your exact requirements but a non-static Segment Tree might work for you. If so, have a look at Layout Management SW, specifically the SegmentTree package. It has the remove feature you need.
If you decide to roll your own, might I suggest open sourcing it? I'm surprised there isn't an open and easy Interval Tree available already.
