Interface TriFunction<T,U,V,R>
-
- Type Parameters:
T
- the type of the first function argumentU
- the type of the second function argumentV
- the type of the third function argumentR
- the type of the function result
- Functional Interface:
- This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
@FunctionalInterface public interface TriFunction<T,U,V,R>
Represents a function that accepts three arguments and produces a result. This is the tri-arity specialization of Function. This is a functional interface whose functional method isapply(Object, Object, Object)

Method Detail
-
apply
R apply(T t, U u, V v)
Applies this function to the given arguments.- Parameters:
t
- the first function argumentu
- the second function argumentv
- the third function argument- Returns:
- the function result
-
andThen
default <W> TriFunction<T,U,V,W> andThen(Function<? super R,? extends W> after)
Returns a composed function that first applies this function to its input, and then applies theafter
function to the result. If evaluation of either function throws an exception, it is relayed to the caller of the composed function.- Type Parameters:
W
- 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
- ifafter
is null
