Interface TriFunction<A,B,C,R>

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.

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.

Method Summary

Modifier and Type	Method	Description
default <R1> TriFunction<A,B,C,R1>	andThen(Function<? super R,? extends R1> after)	Returns a composed function that first applies this function to its input, and then applies the after function to the result.
R	apply(A firstArgument, B secondArgument, C thirdArgument)	Applies this function to the given arguments.

Method Details

apply

R apply(A firstArgument,
 B secondArgument,
 C thirdArgument)

Applies this function to the given arguments.

Parameters:

firstArgument - The first function argument.

secondArgument - The second function argument.

thirdArgument - The third function argument.

Returns:

The function result.

andThen

@API(status=STABLE,
     since="0.1.0")
default <R1> TriFunction<A,B,C,R1> andThen(Function<? super R,? extends R1> 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:

R1 - The type of the 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.
