队列的限制大小<T>在 C++ 中

2022-01-21 00:00:00 queue limit containers c++

我注意到类似问题的主题:Limit size of Queue<T>在 .NET 中?这正是我想要做的,但我使用的不是 .net,而是 GNU C++.我没有引用 GNU C++ 中的基类,因此 super.***() 之类的 java 或 base.***() 之类的 .net 将不起作用.我一直在尝试从队列类继承,但结果是徒劳的.

I notice the thread of similar question: Limit size of Queue<T> in .NET? That's exactly what I want to do, but I am not using .net but GNU C++. I have no reference to the base class in GNU C++, so java like super.***() or .net like base.***() will not work. I have been trying to inherit from queue class but it turns out in vain.

我想做什么:指定队列的大小,当队列满时自动出队.具体来说:如果我的队列的最大大小为2,当我推送第3个项目时,会在推送新项目之前自动弹出第1个项目.

What I want to do: specify the size of the queue, and automatically dequeue when the queue is full. To be specific: if the maximum size of my queue is 2, when I push the 3rd item, the 1st item will be automatically popped out before pushing the new item.

如何实现这样的队列?

谢谢.

推荐答案

创建一个封装队列的新类,并在新类中强制执行大小限制.

Make a new class that encapsulates the queue and enforce a size limit in the new class.
