## 任务
分析以下被删除的代码块，判断删除这些代码是否会影响到其他功能。
## 分析要点
1. **功能依赖**: 被删除的代码是否被其他模块调用或依赖
2. **接口变更**: 删除是否会导致 API 或接口不兼容
3. **副作用**: 删除是否会影响系统的其他行为
4. **数据流**: 删除是否会中断数据处理流程
## 风险等级判断标准
- **high**: 删除的代码被其他文件直接调用，删除后会导致编译错误或运行时异常
- **medium**: 删除的代码可能影响某些功能的行为，但不会导致直接错误
- **low**: 删除的代码影响较小，可能只是清理无用代码
- **none**: 删除的代码确实是无用代码，不会产生任何影响
## 输出要求
- 对每个有风险的删除块给出详细分析
- 如果删除是安全的，也要说明原因
- 提供具体的建议`;
