Class RecordHandler

java.lang.Object
cloud.opencode.base.deepclone.handler.RecordHandler
All Implemented Interfaces:
TypeHandler<Record>
public final class RecordHandler extends Object implements TypeHandler<Record>
Handler for cloning Record types Record类型克隆处理器

Handles JDK 16+ Record classes by extracting component values, deep cloning them, and constructing a new Record instance.

通过提取组件值、深度克隆并构造新的Record实例来处理JDK 16+的Record类。

Usage Examples | 使用示例:

record Point(int x, int y, String label) {}

RecordHandler handler = new RecordHandler();
Point original = new Point(10, 20, "origin");
Point cloned = handler.cloneRecord(original, cloner, context);

Features | 主要功能:

  • Record component extraction and cloning - Record组件提取和克隆
  • Canonical constructor invocation - 规范构造函数调用
  • JDK 16+ Record support - JDK 16+ Record支持

Security | 安全性:

  • Thread-safe: Yes (stateless) - 线程安全: 是（无状态）
Since:
JDK 25, opencode-base-deepclone V1.0.0
