public class ObjectScatterSet<KType>
extends ObjectHashSet<KType>
Same as
ObjectHashSet
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
Description copied from class:ObjectHashSet
Returns a hash code for the given key. The default implementation mixes the hash of the key withObjectHashSet.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.- Overrides:

from
Create a set from a variable number of arguments or an array ofObject
. The elements are copied from the argument to the internal buffer.
