public class FloatScatterSet
extends FloatHashSet

Same as FloatHashSet 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(float key)

Description copied from class: FloatHashSet

Returns a hash code for the given key. The default implementation mixes the hash of the key with FloatHashSet.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 FloatScatterSet from(float... elements)

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