@Generated(date="2023-10-26T04:33:09+0000", value="KTypeVTypeScatterMap.java") public class CharShortScatterMap extends CharShortHashMap
Same as CharShortHashMap 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(char key)
      Description copied from class: CharShortHashMap
      Returns a hash code for the given key.

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

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