  All Methods

  Modifier and Type	Method	Description
  default <V> BiFunction<T,U,V>	andThen (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.
  R	apply (T t, U u)	Applies this function to the given arguments.

• Method Detail

  • apply

    R apply(T t,
     U u)

    Applies this function to the given arguments.

    Parameters:

    t - the first function argument

    u - the second function argument

    Returns:

    the function result

  • andThen

    default <V> BiFunction<T,U,V> andThen(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
