如何在运行时获取C ++对象名? [英] How to 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(例如通过RTTI获取对象的类型)吗?我希望该对象能够打印其名称.

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

推荐答案

不可能.对于事物，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.

您最好的选择是在对象构造函数中添加一个字符串参数，并在其创建时为其命名.

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