对象从容器中删除自身 [英] Object delete itself from container

问题描述

所以我有一个容器(任何类型，可能是 std::map 或 std::vector)，它包含一个类的对象，其中一些网络事物在一个线程中运行，检查它是否仍然连接(线程在内部定义该类并在构造时启动).

So I have a container(any kind, probably std::map or std::vector) which contains objects of a class with some network thing running in a thread that checks if it is still connected (the thread is defined inside that class and launches when constructed).

有什么方法可以让对象在断开连接时从容器中删除自己，或者我应该将线程移到对象之外并使用该类来存储数据?

Is there any way I can make the object delete itself from the container when its disconnected or should I move the thread outside the object and use that class just to store data?

推荐答案

我会有卸载队列.

当一个线程注意到连接断开时，它会将对象(和 continer)注册到卸载队列中，尽可能地让一切都上升，然后线程终止.

When a thread notices that the connection is down it registers the object (and continer) with the unload queue tides everything up as much as possible then the thred terminates.

然后一个单独的线程位于卸载队列中.它的唯一目的是监视队列.当它在队列中看到一个新对象时，将其从容器中移除，然后将其销毁(根据需要与对象线程同步).

A separate thread is then inside the unload queue. Its sole purpose is to monitor the queue. When it sees a new object on the queue, remove it from the container and then destroy it (syncing with the objects thread as required).
