也许意味着:
Myclass obj;
然后,你想要知道物体的名称是obj
,你想通过thi
做到这一点。
Answer is:
No You cannot. There is no reflection available in C++.
让我们承担以下职能:getName(
),将物体的“名称”退回。 你们期望以下法典能取得什么结果?
struct Object {
Object() { getName(); }
void getName() { cout << getName(this) << endl; }
};
int main() {
new Object;
}
或者,如何做到这一点?
int main() {
Object o;
Object& r = o;
r.getName(); //should it print `r` or `o`?
}
简言之,当然没有。
是:
#include <iostream>
#include <typeinfo>
struct C
{
C(){
std::cout<<typeid(*this).name()<<std::endl;
}
};
int main() {
C c;
}
