    • Method Detail

      • hashKey

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

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

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