# TaskGroup::WaitFor
|
||
|
||
```cpp
|
||
bool WaitFor(std::chrono::milliseconds timeout)
|
||
```
|
||
|
||
等待任务组中所有任务完成，可在超时后返回。
|
||
|
||
**参数：**
|
||
- `timeout` - 最大等待时间
|
||
|
||
**返回：** `bool` - 所有任务在超时前完成返回 true，超时返回 false
|
||
|
||
**复杂度：** O(n)
|
||
|
||
**示例：**
|
||
|
||
```cpp
|
||
TaskGroup* group = TaskSystem::Get().CreateTaskGroup();
|
||
|
||
for (int i = 0; i < 5; ++i) {
|
||
group->AddTask([i]() {
|
||
Thread::Sleep(i * 100);
|
||
printf("Task %d done\n", i);
|
||
});
|
||
}
|
||
|
||
if (group->WaitFor(std::chrono::seconds(1))) {
|
||
printf("All tasks completed within 1 second\n");
|
||
} else {
|
||
printf("Timeout! Some tasks still running\n");
|
||
printf("Progress: %.1f%%\n", group->GetProgress() * 100.0f);
|
||
}
|
||
```
