      Modifier and Type Method Description
      int hash​(byte[] payload)
      Hashes a byte array efficiently.
      int hash​(int hashcode)
      An incremental version of the hash function, that spreads a pre-calculated hash code, such as one derived from Object.hashCode().
      int hash​(Object o)
      A helper that calculates the hashcode of an object, choosing the optimal mechanism of hash calculation after considering the type of the object (byte array, String or Object).
