- 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

# TaskGroup
|
||
|
||
**命名空间**: `XCEngine::Threading`
|
||
|
||
**类型**: `class`
|
||
|
||
**头文件**: `XCEngine/Threading/TaskGroup.h`
|
||
|
||
**描述**: 管理一组相关任务的执行和同步
|
||
|
||
## 概述
|
||
|
||
TaskGroup 用于将多个相关任务组织在一起，统一管理它们的执行和同步。任务组内的任务可以声明依赖关系，确保任务按照正确的顺序执行。支持任务优先级设置、完成回调、进度查询和取消操作。
|
||
|
||
主要功能：
|
||
- 添加任务（ITask 对象或函数回调）
|
||
- 声明任务间依赖关系
|
||
- 等待所有任务完成
|
||
- 设置完成回调
|
||
- 查询完成进度
|
||
- 取消未执行的任务
|
||
|

## 公共方法
|
||
|
||
| 方法 | 描述 |
|
||
|------|------|
|
||
| [`Task()`](constructor.md) | 默认构造函数 |
|
||
| [`~Task()`](destructor.md) | 析构函数 |
|
||
| [`AddTask`](add-task.md) | 添加任务到组（支持 ITask 或 Callback） |
|
||
| [`AddDependency`](add-dependency.md) | 添加任务依赖关系 |
|
||
| [`Wait`](wait.md) | 阻塞等待所有任务完成 |
|
||
| [`WaitFor`](wait-for.md) | 等待指定超时时间 |
|
||
| [`SetCompleteCallback`](set-complete-callback.md) | 设置完成回调函数 |
|
||
| [`IsComplete`](is-complete.md) | 检查所有任务是否完成 |
|
||
| [`GetProgress`](get-progress.md) | 获取任务组完成进度 |
|
||
| [`Cancel`](cancel.md) | 取消所有未执行的任务 |

## 使用示例
|
||
|
||
```cpp
|
||
#include "XCEngine/Threading/TaskGroup.h"
|
||
#include "XCEngine/Threading/Task.h"
|
||
#include <iostream>
|
||
|
||
using namespace XCEngine::Threading;
|
||
|
||
class MyTask : public ITask {
|
||
public:
|
||
explicit MyTask(const std::string& name) : m_name(name) {}
|
||
|
||
void Execute() override {
|
||
std::cout << "Task " << m_name << " executing\n";
|
||
}
|
||
|
||
void OnComplete() override {
|
||
std::cout << "Task " << m_name << " completed\n";
|
||
}
|
||
|
||
private:
|
||
std::string m_name;
|
||
};
|
||
|
||
int main() {
|
||
TaskGroup group;
|
||
|
||
uint64_t task1 = group.AddTask(std::make_unique<MyTask>("Task1"));
|
||
uint64_t task2 = group.AddTask([]() {
|
||
std::cout << "Lambda task executing\n";
|
||
}, TaskPriority::High);
|
||
|
||
group.AddDependency(task2, task1);
|
||
|
||
group.SetCompleteCallback([]() {
|
||
std::cout << "All tasks completed!\n";
|
||
});
|
||
|
||
group.Wait();
|
||
|
||
std::cout << "Progress: " << group.GetProgress() * 100 << "%\n";
|
||
|
||
return 0;
|
||
}
|
||
```
