# TaskSystem::Submit
|
||
|
|
|
||
|
|
将任务提交到任务系统调度执行。有两个重载版本。
|
||
|
|
|
||
|
|
## 重载 1: 提交 ITask 对象
|
||
|
|
|
||
|
|
```cpp
|
||
|
|
uint64_t Submit(std::unique_ptr<ITask> task)
|
||
|
|
```
|
||
|
|
|
||
|
|
提交一个 ITask 对象到任务队列。
|
||
|
|
|
||
|
|
**参数：**
|
||
|
|
- `task` - 要提交的任务对象
|
||
|
|
|
||
|
|
**返回：** `uint64_t` - 分配的任务 ID
|
||
|
|
|
||
|
|
**复杂度：** O(log n)
|
||
|
|
|
||
|
|
## 重载 2: 提交 lambda 任务
|
||
|
|
|
||
|
|
```cpp
|
||
|
|
uint64_t Submit(std::function<void()>&& func, TaskPriority priority = TaskPriority::Normal)
|
||
|
|
```
|
||
|
|
|
||
|
|
将可调用对象包装为任务提交。
|
||
|
|
|
||
|
|
**参数：**
|
||
|
|
- `func` - 要执行的可调用对象
|
||
|
|
- `priority` - 任务优先级，默认 TaskPriority::Normal
|
||
|
|
|
||
|
|
**返回：** `uint64_t` - 分配的任务 ID
|
||
|
|
|
||
|
|
**复杂度：** O(log n)
|
||
|
|
|
||
|
|
**示例：**
|
||
|
|
|
||
|
|
```cpp
|
||
|
|
// 提交自定义任务
|
||
|
|
class MyTask : public ITask {
|
||
|
|
public:
|
||
|
|
void Execute() override { printf("MyTask running\n"); }
|
||
|
|
};
|
||
|
|
uint64_t id1 = TaskSystem::Get().Submit(std::make_unique<MyTask>());
|
||
|
|
|
||
|
|
// 提交 lambda
|
||
|
|
uint64_t id2 = TaskSystem::Get().Submit([]() {
|
||
|
|
printf("Lambda task\n");
|
||
|
|
});
|
||
|
|
|
||
|
|
uint64_t id3 = TaskSystem::Get().Submit([]() {
|
||
|
|
HeavyCompute();
|
||
|
|
}, TaskPriority::High);
|
||
|
|
|
||
|
|
// 等待任务完成
|
||
|
|
TaskSystem::Get().Wait(id1);
|
||
|
|
TaskSystem::Get().Wait(id2);
|
||
|
|
TaskSystem::Get().Wait(id3);
|
||
|
|
```
