JSON Patch - RFC 6902 Implementation JSON Patch - RFC 6902 实现

This class implements JSON Patch (RFC 6902), which defines a format for expressing a sequence of operations to apply to a JSON document.

此类实现 JSON Patch（RFC 6902），定义了一种格式， 用于表示应用于 JSON 文档的操作序列。

Operations | 操作:

  • add - Add a value - 添加值
  • remove - Remove a value - 移除值
  • replace - Replace a value - 替换值
  • move - Move a value - 移动值
  • copy - Copy a value - 复制值
  • test - Test a value - 测试值

Example | 示例:

JsonNode target = OpenJson.parse("{\"name\":\"John\",\"age\":30}");

JsonPatch patch = JsonPatch.builder()
    .replace("/name", JsonNode.of("Jane"))
    .add("/email", JsonNode.of("jane@example.com"))
    .remove("/age")
    .build();

JsonNode result = patch.apply(target);
// Result: {"name":"Jane","email":"jane@example.com"}

Features | 主要功能:

  • RFC 6902 JSON Patch implementation - RFC 6902 JSON Patch实现
  • Six patch operations: add, remove, replace, move, copy, test - 六种补丁操作
  • Builder pattern for constructing patch sequences - 构建补丁序列的构建器模式

Security | 安全性:

  • Thread-safe: Yes (immutable) - 线程安全: 是（不可变）
  • Null-safe: N/A - 空值安全: 不适用

JDK 25, opencode-base-json V1.0.0
