You can simply move the member directly in the return statement :
class foo
{
public:
bar steal_the_moveable_object()
{
return std::move(moveable_object);
}
private:
bar moveable_object;
};
Beware that this may not be a good idea though. Consider using the following instead so that the method can only called on R-Values :
class foo
{
public:
bar steal_the_moveable_object() && // add '&&' here
{
return std::move(moveable_object);
}
private:
bar moveable_object;
};
int main()
{
foo f;
//auto x = f.steal_the_moveable_object(); // Compiler error
auto y = std::move(f).steal_the_moveable_object();
return 0;
}
