I think reference_existing_object will work.
And in my opinion, you'd better be careful if you expect that the c++ code
and python code are using the same singleton instance.
Because there're two Singleton::_instance if you export the Singleton class
to Python. one at c++ side, the other at python
HI,
The am not sure if which call policy I should be using for this particular use
case,
class Singleton
{
public:
Singleton* create()
{
if(!_instance)
{
_instance = new Singleton();
}
return _instance;
}
static Singleton* _instance;
}
