      • andThen

        default <V> FailableBiFunction<T,​U,​V,​E> andThen​(FailableFunction<? super R,​? extends V,​E> after)
        Returns a composed FailableBiFunction that like BiFunction.andThen(Function).
        Type Parameters:
        V - the output type of the after function, and of the composed function.
        Parameters:
        after - the operation to perform after this one.
        Returns:
        a composed FailableBiFunction that like BiFunction.andThen(Function).
        Throws:
        java.lang.NullPointerException - when after is null.
