@Generated(date="2021-05-28T03:45:41+0000", value="KTypeScatterSet.java") public class ShortScatterSet extends ShortHashSet
Same asShortHashSet
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(short key)
Description copied from class:ShortHashSet
Returns a hash code for the given key. The default implementation mixes the hash of the key withShortHashSet.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:
hashKey
in classShortHashSet
-
from
public static ShortScatterSet from(short... elements)
Create a set from a variable number of arguments or an array ofshort
. The elements are copied from the argument to the internal buffer.
-
removeAll
public int removeAll(ShortLookupContainer c)
Default implementation uses a predicate for removal.- Specified by:
removeAll
in interfaceShortCollection
- Returns:
- Returns the number of removed elements.
-
retainAll
public int retainAll(ShortLookupContainer c)
Default implementation uses a predicate for retaining.- Specified by:
retainAll
in interfaceShortCollection
- Returns:
- Returns the number of removed elements.
-
retainAll
public int retainAll(ShortPredicate predicate)
Default implementation redirects toShortCollection.removeAll(ShortPredicate)
and negates the predicate.- Specified by:
retainAll
in interfaceShortCollection
- Returns:
- Returns the number of removed elements.
-
toString
public java.lang.String toString()
Convert the contents of this container to a human-friendly string.- Overrides:
toString
