multithreading - 如何将线程添加到std::vector

Question

我正在尝试填补我的载体:

...    
auto f = std::bind(&ScheduledExecutor::complete_after, std::placeholders::_1, std::placeholders::_2);
threadPoolVector.push_back(std::thread(f, this, delay));
...

在将线程推送到向量之前，如何分离添加线程？

Answer 1

不要分离它们。您可以将std::shared_ptr用于vector中的线程:

std::vector<std::shared_ptr<std::thread>> threadPoolVector;
....
auto f = std::bind(&ScheduledExecutor::complete_after, std::placeholders::_1, std::placeholders::_2);
threadPoolVector.push_back(std::make_shared<std::thread>(f, this, delay));

如果由于某种原因不能使用共享指针，则可以使用 emplace_back() vector方法将线程移至vector:

std::vector<std::thread> threadPoolVector;
...
auto f = std::bind(&ScheduledExecutor::complete_after, std::placeholders::_1, std::placeholders::_2);
threadPoolVector.emplace_back(f, this, delay);
