      • _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
