Class Pow2LengthBitSetRange

java.lang.Object

com.google.uzaygezen.core.Pow2LengthBitSetRange

public class Pow2LengthBitSetRange
extends Object

BitVector range with a power of 2 length, where the inclusive start has all the level lowest bits set to zero, and the lowest level bits of the inclusive end are all set to one. A single point is represented as a bit set with level=0.

Caveat: As soon as the underlying bit set is modified, an instance and all its clones should be considered invalid. We have to make this compromise for performance reasons.
