public class ByteScatterSet
extends ByteHashSet
```
Same as ByteHashSet 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.

    Description copied from class: ByteHashSet
    
    Returns a hash code for the given key. The default implementation mixes the hash of the key with ByteHashSet.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.

```
public static ByteScatterSet from(byte... elements)
```
    Create a set from a variable number of arguments or an array of byte. The elements are copied from the argument to the internal buffer.
