public class DoubleByteScatterMap
extends DoubleByteHashMap
DoubleByteHashMap but does not implement per-instance
key mixing strategy and uses a simpler (faster) bit distribution function.
Note: read about important differences between hash and scatter sets.

protected int hashKey(double key)
DoubleByteHashMapThe default implementation mixes the hash of the key with DoubleByteHashMap.keyMixer
to differentiate hash order of keys between hash containers. Helps
alleviate problems resulting from linear conflict resolution in open
addressing.
The output from this function should evenly distribute keys across the entire integer range.
