TriFunction

@FunctionalInterface public abstract interface org.apache.commons.lang3.function.TriFunction<T, U, V, R>

Represents a function that accepts three arguments and produces a result. This is the three-arity specialization of Function.

This is a functional interface whose functional method is #apply(Object, Object, Object).

Parameters:

• <T> – The type of the first argument to the function

• <U> – The type of the second argument to the function

• <V> – The type of the third argument to the function

• <R> – The type of the result of the function

Since:

3.12.0

Methods

andThen(Function)	Returns a composed function that first applies this function to its input, and then applies the after function to the result.
apply(Object, Object, Object)	Applies this function to the given arguments.

public 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 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:

<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:

java.lang.NullPointerException – Thrown if after is null.

public abstract R apply(T t, U u, V v)

Applies this function to the given arguments.

Parameters:

• t – The first function argument

• u – The second function argument

• v – The third function argument

Returns:

The function result
