public class LongFloatScatterMap
extends LongFloatHashMap
Same as
LongFloatHashMap
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(long key) Description copied from class:LongFloatHashMap
Returns a hash code for the given key.The default implementation mixes the hash of the key with
LongFloatHashMap.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.
