C++ rtti performance
WebC++ 为什么std:：type_info是多态的？,c++,polymorphism,rtti,typeinfo,C++,Polymorphism,Rtti,Typeinfo,是否有理由将std:：type_info指定为多态性？析构函数被指定为虚拟的（在C++的设计和发展中有一条注释是关于“使其多态”的效果）。我真的看不出有什么令人信服的理由。 Web这是“安全的”，在这个意义上，这是有效的c++，并且可以访问所有程序中的返回指针，因为静态本地将在第一个函数调用初始化。代码中使用的每种类型t将有一个静态变量. 但是： 为什么返回非常量指针？这将允许调用者更改静态变量值，这显然不是您想要的

WebMar 14, 2024 · C++ 的 RTTI 整体上比较弱（比如无法枚举成员函数） C++ 的设计哲学是不让用户为其用不着的特性买单，而完整的反射特性显然无论程序员是否会用到，都可能对应用的时间和空间性能产生比较大的影响。 因此 C++ 中的 RTTI 只是方便用户进一步实现完整的反射等机制的一种手段——通过 RTTI，用户可以自行实现自己需要的类型机制，比如反 … WebC++ : Why is RTTI needed for non-polymorphic typeid?To Access My Live Chat Page, On Google, Search for "hows tech developer connect"Here's a secret feature t...
