How can I get this code involving unique_ptr and emplace_back to compile?
- by Neil G
#include <vector>
#include <memory>
using namespace std;
class A {
public:
A(): i(new int) {}
A(A const& a) = delete;
A(A &&a): i(move(a.i)) {}
unique_ptr<int> i;
};
class AGroup {
public:
void AddA(A &&a) { a_.emplace_back(move(a)); }
vector<A> a_;
};
int main() {
AGroup ag;
ag.AddA(A());
return 0;
}
does not compile... (says that unique_ptr's copy constructor is deleted)
I tried replacing move with forward. Not sure if I did it right, but it didn't work for me.
