Public Methods

public abstract 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.

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

public abstract R apply (T t, U u)

Applies this function to the given arguments.

Parameters
t the first function argument
u the second function argument
