- 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
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:
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);
}
