- Fix SpinLock docs: clarify lock()/unlock()/try_lock() are non-const (matching source implementation in SpinLock.h) - Add missing LambdaTask::Execute() method to inherited methods table - Update TaskGroup::Wait() docs: clarify m_pendingCount never decrements causing indefinite block even after all tasks complete (not just unexecuted tasks) - Update TaskGroup::IsComplete() docs: document same m_pendingCount issue causing incorrect return values

# TaskGroup::IsComplete
|
||
|
||
```cpp
|
||
bool IsComplete() const
|
||
```
|
||
|
||
检查任务组中所有任务是否已完成。
|
||
|
||
**参数:** 无
|
||
|
||
**返回:** `bool` - 所有任务完成返回 true,否则返回 false
|
||
|
||
**复杂度:** O(1)
|
||
|
||
**注意:** 由于实现缺陷,`m_pendingCount` 计数器在任务完成后不会递减,因此此方法在所有任务执行完毕后仍会错误地返回 false。
|
||
|
||
**示例:**
|
||
|
||
```cpp
|
||
TaskGroup* group = TaskSystem::Get().CreateTaskGroup();
|
||
|
||
for (int i = 0; i < 100; ++i) {
|
||
group->AddTask([i]() { HeavyCompute(i); });
|
||
}
|
||
|
||
// 非阻塞轮询
|
||
while (!group->IsComplete()) {
|
||
printf("Progress: %.1f%%\n", group->GetProgress() * 100.0f);
|
||
Thread::Sleep(500);
|
||
}
|
||
```
