- Rename D3D12Enum.h to D3D12Enums.h for naming consistency - Fix OpenGL unit test GLAD initialization by using gladLoadGL() instead of gladLoadGLLoader(wglGetProcAddress) for fallback support - Migrate remaining tests to use gtest_discover_tests for granular test discovery (math, core, containers, memory, threading, debug, components, scene, resources, input, opengl) - Remove obsolete TEST_RESOURCES_DIR and copy_directory commands from OpenGL unit test CMakeLists (minimal/Res doesn't exist) - Update TEST_SPEC.md with performance metrics and per-module build/test commands for faster development workflow - Update CMake path references to use lowercase paths

# Mutex
|
||
|
||
**命名空间**: `XCEngine::Threading`
|
||
|
||
**类型**: `class`
|
||
|
||
**头文件**: `XCEngine/Threading/Mutex.h`
|
||
|
||
**描述**: 互斥锁，封装 std::mutex 提供线程同步
|
||
|
||
## 概述
|
||
|
||
Mutex 类是对 std::mutex 的封装，提供线程安全的互斥访问机制。该类确保同一时刻只有一个线程可以访问受保护的资源，防止数据竞争和竞态条件。
|
||
|
||
该类提供两套接口：
|
||
- `Lock/Unlock/TryLock`：XCEngine 风格接口
|
||
- `lock/unlock/try_lock`：STL 兼容接口（const 成员函数）
|
||
|
||
## 公共方法
|
||
|
||
| 方法 | 描述 |
|
||
|------|------|
|
||
| [`Lock`](lock.md) | 获取互斥锁（非 const） |
|
||
| [`Unlock`](unlock.md) | 释放互斥锁（非 const） |
|
||
| [`TryLock`](trylock.md) | 尝试获取互斥锁（非 const） |
|
||
| [`lock`](lock-const.md) | 获取互斥锁（const，STL 兼容） |
|
||
| [`unlock`](unlock-const.md) | 释放互斥锁（const，STL 兼容） |
|
||
| [`try_lock`](try-lock-const.md) | 尝试获取互斥锁（const，STL 兼容） |
|
||
|
||
## 使用示例
|
||
|
||
```cpp
|
||
#include "XCEngine/Threading/Mutex.h"
|
||
#include <thread>
|
||
#include <iostream>
|
||
|
||
XCEngine::Threading::Mutex mutex;
|
||
int sharedData = 0;
|
||
|
||
void increment() {
|
||
mutex.lock();
|
||
++sharedData;
|
||
mutex.unlock();
|
||
}
|
||
|
||
int main() {
|
||
std::thread t1(increment);
|
||
std::thread t2(increment);
|
||
|
||
t1.join();
|
||
t2.join();
|
||
|
||
std::cout << "sharedData = " << sharedData << std::endl;
|
||
return 0;
|
||
}
|
||
```
