Interface Remote.Function<T,​R>

    • Method Detail

      • compose

        default <V> Remote.Function<V,​R> compose​(Remote.Function<? super V,​? extends T> before)
        Returns a composed function that first applies the before function to its input, and then applies this function to the result. If evaluation of either function throws an exception, it is relayed to the caller of the composed function.
        Type Parameters:
        V - the type of input to the before function, and to the composed function
        Parameters:
        before - the function to apply before this function is applied
        Returns:
        a composed function that first applies the before function and then applies this function
        Throws:
        NullPointerException - if before is null

      • andThen

        default <V> Remote.Function<T,​V> andThen​(Remote.Function<? super R,​? extends V> after)
        Returns a composed function that first applies this function to its input, and then applies the after function to the result. If evaluation of either function throws an exception, it is relayed to the caller of the composed function.
        Type Parameters:
        V - the type of output of the after function, and of the composed function
        Parameters:
        after - the function to apply after this function is applied
        Returns:
        a composed function that first applies this function and then applies the after function
        Throws:
        NullPointerException - if after is null

      • identity

        static <T> Remote.Function<T,​T> identity()
        Returns a function that always returns its input argument.
        Type Parameters:
        T - the type of the input and output objects to the function
        Returns:
        a function that always returns its input argument
