@Generated(date="2024-05-16T12:00:00+0000", value="KTypeVTypeScatterMap.java") public class ObjectFloatScatterMap<KType> extends ObjectFloatHashMap<KType>
Same asObjectFloatHashMap
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.

Method Detail

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