    • _4

      _4 _4()
      Retrieve the fourth element.
      Returns:
      the fourth element

    • into

      default <R> R into(Fn4<? super _1, ? super _2, ? super _3, ? super _4, ? extends R> fn)
      Destructure and apply this product to a function accepting the same number of arguments as this product's slots. This can be thought of as a kind of dual to uncurrying a function and applying a product to it.
      Type Parameters:
      R - the return type of the function
      Parameters:
      fn - the function to apply
      Returns:
      the result of applying the destructured product to the function
