Interface CharUnaryOperator

All Superinterfaces:

java.util.function.Function<java.lang.Character,java.lang.Character>, java.util.function.IntUnaryOperator, java.util.function.UnaryOperator<java.lang.Character>

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 CharUnaryOperator
extends java.util.function.UnaryOperator<java.lang.Character>, java.util.function.IntUnaryOperator

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

Method Summary

Modifier and Type	Method and Description
char	apply(char x) Computes the operator on the given input.
default java.lang.Character	apply(java.lang.Character x) Deprecated. Please use the corresponding type-specific method instead.
default int	applyAsInt(int x) Deprecated. Please use apply(char).
