      public void computeHash(Hasher hasher)
      Description copied from interface: IHashable
      Computes the hash of the implementing object using the provided hasher. The implementation should call appropriate put methods on the hasher for all fields that should contribute to the hash value.
      Specified by:
      computeHash in interface IHashable
      Parameters:
      hasher - the hasher instance to use for hash computation
