Class SimpleObjectIdResolver

java.lang.Object
cloud.opencode.base.json.identity.SimpleObjectIdResolver
All Implemented Interfaces:
ObjectIdResolver
public class SimpleObjectIdResolver extends Object implements ObjectIdResolver
Simple Object ID Resolver - Default HashMap-Based Identity Resolver 简单对象 ID 解析器 - 默认基于 HashMap 的身份解析器

A straightforward implementation of ObjectIdResolver that uses a HashMap to store and retrieve object identity mappings. Each deserialization context should use its own instance.

一个简单的 ObjectIdResolver 实现，使用 HashMap 存储和检索对象身份映射。每个反序列化上下文应使用自己的实例。

Example | 示例:

SimpleObjectIdResolver resolver = new SimpleObjectIdResolver();
ObjectIdGenerator.IdKey key = new ObjectIdGenerator.IdKey(User.class, Void.class, 42);
resolver.bindItem(key, user);
Object found = resolver.resolveId(key); // returns user

Security | 安全性:

  • Thread-safe: No (single-threaded deserialization context) - 线程安全: 否（单线程反序列化上下文）
  • Null-safe: Rejects null ID keys - 空值安全: 拒绝空 ID 键
