Copy Constructors and calling functions
- by helixed
Hello,
I'm trying to call an accessor function in a copy constructor but it's not working. Here's an example of my problem:
A.h
class A {
public:
//Constructor
A(int d);
//Copy Constructor
A(const A &rhs);
//accessor for data
int getData();
//mutator for data
void setData(int d);
private:
int data;
};
A.cpp
#include "A.h"
//Constructor
A::A(int d) {
this->setData(d);
}
//Copy Constructor
A::A(const A &rhs) {
this->setData(rhs.getData());
}
//accessor for data
int A::getData() {
return data;
}
//mutator for data
void A::setData(int d) {
data = d;
}
When I try to compile this, I get the following error:
error: passing 'const A' as 'this' argument of 'int A::getData()' discards qualifiers
If I change rhs.getData() to rhs.data, then the constructor works fine. Am I not allowed to call functions in a copy constructor? Could somebody please tell me what I'm doing wrong?
Thanks,
helixed
