    • Method Detail

      • hashKey

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

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

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