I search a method to overload operator of delete[] or suitable destructor for a code:
#include <iostream>
#include <string>
using namespace std;
class A {
private:
string name;
public:
A(string name){
this->name=name;
};
~A(){
cout<<"Destructor. Destroyed "<<name<<"\n";
};
void operator delete(void* p, A* a){
cout<<"-Delete "<<a->name<<"\n";
};
void operator delete(void* pointer){
cout<<"Delete"<<"\n";
};
void operator delete[](void* pointer){
cout<<"Delete[]"<<"\n";
};
};
int main(){
int number = 5;
A** a = new A* [ number ];
delete [] a;
system("pause");
return 0;
};
But whatever I tried default delete[] is started each time from the file delete2.cpp. What do I do wrong? [ADDED] Added an attempt to overload delete[].
Your code is not creating or destroy instances of A, only pointers to it.
#include <iostream>
#include <string>
using namespace std;
class A {
private:
string name;
public:
A() {}
A(string name){
this->name=name;
};
~A(){
cout<<"Destructor. Destroyed "<<name<<"\n";
};
void operator delete(void* p, A* a){
cout<<"-Delete "<<a->name<<"\n";
};
void operator delete(void* pointer){
cout<<"Delete"<<"\n";
};
void operator delete[](void* pointer){
cout<<"Delete[]"<<"\n";
};
};
int main(){
int number = 5;
A* a = new A[ number ];
delete [] a;
system("pause");
return 0;
};
Calls operator[] as expected: http://ideone.com/EuS3Hi
