@Generated(date="2024-05-16T12:00:00+0000", value="KTypeScatterSet.java") public class LongScatterSet extends LongHashSet
Same asLongHashSet
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(long key)
Description copied from class:LongHashSet
Returns a hash code for the given key. The default implementation mixes the hash of the key withLongHashSet.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
public static LongScatterSet from(long... elements)
Create a set from a variable number of arguments or an array oflong
. The elements are copied from the argument to the internal buffer.
