- 重组文档目录结构: 每个模块的概述页移动到模块子目录 - 重命名 index.md 为 main.md - 修正所有模块文档中的错误: - math: FromEuler→FromEulerAngles, TransformDirection 包含缩放, Box 是 OBB, Color::ToRGBA 格式 - containers: 新增 operator==/!= 文档, 补充 std::hash DJB 算法细节 - core: 修复 types 链接错误 - debug: LogLevelToString 返回大写, timestamp 是秒, Profiler 空实现标注, Windows API vs ANSI - memory: 修复头文件路径, malloc vs operator new, 新增方法文档 - resources: 修复 Shader/Texture 链接错误 - threading: TaskSystem::Wait 空实现标注, ReadWriteLock 重入描述, LambdaTask 链接 - 验证: fix_links.py 确认 0 个断裂引用

String::Clear
void Clear();
清空字符串内容,将长度设为 0,但不释放已分配的内存。
参数: 无
返回: 无
复杂度: O(1)
示例:
#include "XCEngine/Containers/String.h"
#include <iostream>
int main() {
XCEngine::Containers::String s("Hello World");
std::cout << "Before clear - Length: " << s.Length()
<< ", Capacity: " << s.Capacity() << std::endl;
// 输出: Before clear - Length: 11, Capacity: 12
s.Clear();
std::cout << "After clear - Length: " << s.Length()
<< ", Capacity: " << s.Capacity() << std::endl;
// 输出: After clear - Length: 0, Capacity: 12
std::cout << "Empty: " << s.Empty() << std::endl; // 输出: Empty: 1
return 0;
}
