在运行时获取C ++对象名称 [英] get C++ object name in run time

问题描述

我可以在运行时获取对象的名称（如通过RTTI获取对象的类型）？我希望对象能够打印它的名称。

Can I get object's name in run time (like getting object's type via RTTI)? I want the object to be able to print its name.

谢谢。

推荐答案

它不可能。对于on，对象没有唯一的名称。

Its not possible. For on thing, an object doesn't have a unique name.

A a;
A& ar = a;  // both a and ar refer to the same object

new A;  // the object created doesn't have a name

A* ap = new A[100];  // either all 100 objects share the same name, or need to 
                     // know that they are part of an array.

最好的办法是在对象构造函数中添加一个字符串参数，

Your best bet is to add a string argument to the objects constructor, and give it a name when its created.
