Class MirrorLinkAnnotationPostProcessor

java.lang.Object

cn.hutool.core.annotation.AbstractLinkAnnotationPostProcessor

cn.hutool.core.annotation.MirrorLinkAnnotationPostProcessor

All Implemented Interfaces:

SynthesizedAnnotationPostProcessor, Comparable<SynthesizedAnnotationPostProcessor>

public class MirrorLinkAnnotationPostProcessor
extends AbstractLinkAnnotationPostProcessor

用于处理注解对象中带有Link注解，且Link.type()为RelationType.MIRROR_FOR的属性。
当该处理器执行完毕后，原始合成注解中被Link注解的属性与Link注解指向的目标注解的属性， 都将会被被包装并替换为MirroredAnnotationAttribute。

                                      AnnotationAttribute linkedAttribute)

将存在镜像关系的合成注解属性分别包装为MirroredAnnotationAttribute对象， 并使用包装后MirroredAnnotationAttribute替换在它们对应合成注解实例中的AnnotationAttribute

Specified by:

processLinkedAttribute in class AbstractLinkAnnotationPostProcessor

Parameters:

synthesizer - 注解合成器

annotation - originalAttribute上的Link注解对象

originalAnnotation - 当前正在处理的SynthesizedAnnotation对象

originalAttribute - originalAnnotation上的待处理的属性

linkedAnnotation - Link指向的关联注解对象

linkedAttribute - Link指向的originalAnnotation中的关联属性，该参数可能为空
