Interface Function4<T1,T2,T3,T4,R>

Type Parameters:

T1 - the type of the first argument to the function

T2 - the type of the second argument to the function

T3 - the type of the third argument to the function

T4 - the type of the fourd argument to the function

R - the type of the result of the function

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 Function4<T1,T2,T3,T4,R>

This is the three-arity specialization of Function.

Method Summary

Modifier and Type	Method and Description
default <R2> Function4<T1,T2,T3,T4,R2>	andThen(java.util.function.Function<? super R,? extends R2> after) Returns a composed function that first applies this function
R	apply(T1 t1, T2 t2, T3 t3, T4 t4) Applies this function to the given arguments.

Method Detail

apply

R apply(T1 t1,
        T2 t2,
        T3 t3,
        T4 t4)

Applies this function to the given arguments.

Parameters:

t1 - the first function argument

t2 - the second function argument

t3 - the third function argument

t4 - the fourd function argument

Returns:

the function result

andThen

default <R2> Function4<T1,T2,T3,T4,R2> andThen(java.util.function.Function<? super R,? extends R2> after)

Returns a composed function that first applies this function

Type Parameters:

R2 - 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 - if after is null
