Interface TriFunction<A,B,C,RESULT>

Type Parameters:

A - The type of the first argument to the function

B - The type of the second argument to the function

C - The type of the third argument to the function

RESULT - The type of the result of the function

All Superinterfaces:

AtlanticFunction<A,BiFunction<B,C,RESULT>>, AtlanticLambda

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<A,B,C,RESULT>
extends AtlanticFunction<A,BiFunction<B,C,RESULT>>

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).

Method Summary

Modifier and Type	Method and Description
default <AFTER_RESULT> TriFunction<A,B,C,AFTER_RESULT>	andThen(Function<? super RESULT,? extends AFTER_RESULT> after) Returns a composed trifunction that first applies this trifunction to its input, and then applies the after function to the result.
RESULT	apply(A a, B b, C c) Applies this function to the given arguments.
default BiFunction<B,C,RESULT>	downgrade(A a) Converts this AtlanticFunction into another that has the same parameters save for the first one.

Method Detail

apply

RESULT apply(A a,
             B b,
             C c)
      throws Throwable

Applies this function to the given arguments.

Parameters:

a - The first function argument.

b - The second function argument.

c - The third function argument.

Returns:

Object The function result.

Throws:

Throwable - Any exception that the operation will throw.

downgrade

default BiFunction<B,C,RESULT> downgrade(A a)

Description copied from interface: AtlanticFunction

Converts this AtlanticFunction into another that has the same parameters save for the first one. Invocation of the returned AtlanticLambda will call this one with the provided parameter.

Specified by:

downgrade in interface AtlanticFunction<A,BiFunction<B,C,RESULT>>

Parameters:

a - The parameter that will be passed to this AtlanticFunction.

Returns:

AtlanticLambda This lambda without the first parameter.

andThen

default <AFTER_RESULT> TriFunction<A,B,C,AFTER_RESULT> andThen(Function<? super RESULT,? extends AFTER_RESULT> after)

Returns a composed trifunction that first applies this trifunction 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:

AFTER_RESULT - 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:

TriFunction A composed trifunction that first applies this function and then applies the after function
