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 FloatUnaryOperator

A Type Specific Function interface that reduces boxing/unboxing and fills the gaps of interfaces that are missing.

Method Summary

Modifier and Type	Method and Description
default FloatUnaryOperator	andThen(FloatUnaryOperator after) Returns a composed function that first applies this function to its input, and then applies the after function to the result.
float	applyAsFloat(float k) Type Specific get function to reduce boxing/unboxing
default FloatUnaryOperator	compose(FloatUnaryOperator before) Returns a composed function that first applies the before function to its input, and then applies this function to the result.
static FloatUnaryOperator	identity() Creates a Default function that returns the input provided.

Method Detail

applyAsFloat

float applyAsFloat(float k)

Type Specific get function to reduce boxing/unboxing

Parameters:

k - the value that should be processed

Returns:

the result of the function

identity

static FloatUnaryOperator identity()

Creates a Default function that returns the input provided.

Returns:

a input returning function

compose

default FloatUnaryOperator compose(FloatUnaryOperator before)

Returns a composed function that first applies the before function to its input, and then applies this function to the result. If evaluation of either function throws an exception, it is relayed to the caller of the composed function.

Parameters:

before - the function that should be used first

Returns:

a composed function with a different starting function.

andThen

default FloatUnaryOperator andThen(FloatUnaryOperator 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.

Parameters:

after - the function that should be used last

Returns:

a composed function with a different starting function.
