    • Method Detail

      • hashKey

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

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

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