public class ShortIntScatterMap
extends ShortIntHashMap
Same as
ShortIntHashMap
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.

hashKey
protected int hashKey(short key) Description copied from class:ShortIntHashMap
Returns a hash code for the given key.The default implementation mixes the hash of the key with
ShortIntHashMap.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.
