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

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

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