如何使用std :: string创建条件断点 [英] how to create conditional breakpoint with std::string

问题描述

假设我有这个功能：

std::string Func1(std::string myString)
{
   //do some string processing 
   std::string newString = Func2(myString)
   return newString;  
}

如果 newString 具有特定的值？ （不更改源）

how do I set a conditional break when newString has a specific value ? (without changing the source)

设置条件 newString ==我的价值

没有工作的断点被禁用，错误重载运算符未找到

didn't work the breakpoints got disabled with an error "overloaded operator not found"

推荐答案

有些搜索没有办法做到这一点。建议的替代方法是将测试放在代码中并添加标准断点：

Some searching has failed to turn up any way to do this. Suggested alternatives are to put the test in your code and add a standard breakpoint:

if (myStr == "xyz")
{
    // Set breakpoint here
}

或建立从个人角色比较中进行测试。即使看着字符串中的个人字符也有点骰子;在Visual Studio 2005中，我不得不挖掘成员变量，如

Or to build up your test from individual character comparisons. Even looking at individual characters in the string is a bit dicey; in Visual Studio 2005 I had to dig down into the member variables like

myStr._Bx._Buf[0] == 'x' && myStr._Bx._Buf[1] == 'y' && myStr._Bx._Buf[2] == 'z'

这两种方法都不是很令人满意。我们应该更好地访问标准库的无所不在的功能。

Neither of these approaches is very satisfactory. We should have better access to a ubiquitous feature of the Standard Library.
