docs: 重构 API 文档结构并修正源码准确性
- 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

# HashMap::Contains
|
||||
|
||||
```cpp
|
||||
bool Contains(const Key& key) const;
|
||||
```
|
||||
|
||||
检查哈希表中是否包含指定的键。
|
||||
|
||||
**参数:**
|
||||
- `key` - 要检查的键
|
||||
|
||||
**返回:** 如果键存在返回 `true`,否则返回 `false`。
|
||||
|
||||
**复杂度:** O(1) 平均,最坏 O(n)
|
||||
|
||||
**示例:**
|
||||
|
||||
```cpp
|
||||
XCEngine::Containers::HashMap<int, const char*> map;
|
||||
map.Insert(1, "one");
|
||||
map.Insert(2, "two");
|
||||
|
||||
if (map.Contains(1)) {
|
||||
std::cout << "Key 1 exists" << std::endl; // 输出 "Key 1 exists"
|
||||
}
|
||||
|
||||
if (!map.Contains(99)) {
|
||||
std::cout << "Key 99 does not exist" << std::endl; // 输出 "Key 99 does not exist"
|
||||
}
|
||||
```
