open fun <V : Any!> andThen(after: Function<in R, out V>!): BiFunction<T, U, V>!
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 | |
|---|---|
<V> |
the type of output of the after function, and of the composed function |
after |
Function<in R, out V>!: the function to apply after this function is applied |
| Return | |
|---|---|
BiFunction<T, U, V>! |
a composed function that first applies this function and then applies the after function |
| Exceptions | |
|---|---|
java.lang.NullPointerException |
if after is null |
