Interface FloatUnaryOperator

All Superinterfaces:

java.util.function.DoubleUnaryOperator, java.util.function.Function<java.lang.Float,java.lang.Float>, java.util.function.UnaryOperator<java.lang.Float>

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
extends java.util.function.UnaryOperator<java.lang.Float>, java.util.function.DoubleUnaryOperator

A type-specific UnaryOperator; provides methods operating both on objects and on primitives.

Since:

8.5.0

UnaryOperator

Method Summary

Modifier and Type	Method and Description
float	apply(float x) Computes the operator on the given input.
default java.lang.Float	apply(java.lang.Float x) Deprecated. Please use the corresponding type-specific method instead.
default double	applyAsDouble(double x) Deprecated. Please use apply(float).
static FloatUnaryOperator	identity() Returns a UnaryOperator that always returns the input unmodified.
static FloatUnaryOperator	negation() Returns a UnaryOperator that always returns the arithmetic negation of the input.
