    • Method Detail

      • hashKey

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

        The default implementation mixes the hash of the key with DoubleObjectHashMap.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:

      • from

        public static <VType> DoubleObjectScatterMap<VType> from​(double[] keys,
                                                                 VType[] values)
        Creates a hash map from two index-aligned arrays of key-value pairs.
