猜测和析构

本文介绍了猜测和析构的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我正在研究roguelike。我有一个全局std :: vector 字符列表（是的，我知道全局变量很糟糕。我还在学习 面向对象的编程。）我还有一个处理程序类，可以将 字符添加到该列表中。 退出处理程序对象的函数会导致析构函数 为角色列表调用？

I''m currently working on a roguelike. I''ve got a global std::vector list of characters (Yes, I know globals are bad. I''m still learning Object Oriented programming.) I''ve also got a handler class to add characters to that list. Could exiting the functions of the handler object cause a destructor to be called for the character list?

推荐答案

我不清楚你到底在做什么，但一般来说，矢量上的 析构函数（是一个全局的）只能在整个程序的 关闭时调用，而向量的元素可能或者可能通过添加/删除向量的元素来构造/销毁。 br />

I''m not clear on exactly what you are doing but in general, the destructor on the vector (being a global) can only be called on the shutdown of the whole program while elements of the vector may or may not be constructed/destroyed by adding/removing elements of the vector.

好​​吧，有些东西正在调用析构函数。我把一个std :: cout放到 析构函数中以确定它是在程序运行时被调用的。这也不是我;从不明确地调用析构函数。

Well, something is calling the destructor. I put a std::cout into the destructor to be sure and it''s being called while the program is running. It''s not me, either; the destructor is never explicitly called.

好​​吧，有些东西正在调用析构函数。我把一个std :: cout放到 析构函数中以确定它是在程序运行时被调用的。这也不是我;析构函数永远不会被明确调用。

你是否擦过了向量中的元素？如果是，析构函数将为每个已擦除的元素调用。 Pierre

Do you ever erase elements from the vector ? If yes, the destructor will be called for each erased element. Pierre
