@Generated(date="2024-02-21T10:44:44+0000", value="KTypeVTypeScatterMap.java") public class ShortCharScatterMap extends ShortCharHashMap
Same as ShortCharHashMap 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 Details

    • hashKey

      protected int hashKey(short key)
      Description copied from class: ShortCharHashMap
      Returns a hash code for the given key.

      The default implementation mixes the hash of the key with ShortCharHashMap.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 class ShortCharHashMap
    • from

      public static ShortCharScatterMap from(short[] keys, char[] values)
      Creates a hash map from two index-aligned arrays of key-value pairs.
