cloud.opencode.base.json.identity.ObjectIdGenerator.IdKey
Record Components:
type - the type of the identified object - 被标识对象的类型
scope - the scope for uniqueness - 唯一性的作用域
key - the actual identity key value - 实际的身份键值
Enclosing class:
ObjectIdGenerator<T>
public static record ObjectIdGenerator.IdKey(Class<?> type, Class<?> scope, Object key) extends Record
ID Key - Composite Key for Object Identity Tracking ID 键 - 用于对象身份跟踪的复合键

A composite key consisting of type, scope, and the actual key value, used for tracking object identity during serialization and deserialization.

由类型、作用域和实际键值组成的复合键，用于在序列化和反序列化期间跟踪对象身份。
