Since Python supports overloading to wrap C++ overload, just list the members as normal:
cdef foobar (int) cdef foobar (int, int) …
Cython understands that we are in C++ mode and can handle all the type conversion as normal. It's interesting that it can also handle an operator overload easily since it is just another hook! For example, let's take the Car class again and perform some operator overriding such as the following:
namespace mynamespace {
class Car {
int doors;
int wheels;
public:
Car ();
~Car ();
Car * operator+(Car *);
void printCar (void);
void setWheels (int x) { wheels = x; };
void setDoors (int x) { doors = x; };
};
};Remember to add these operator-overloading class members to your Cythonized class; otherwise, your Cython will throw the following error:
Invalid operand types for '+' (Car *; Car *)
The Cython declaration of the operator overload looks as you expected:
cdef extern from "cppcode.h" namespace "mynamespace":
cppclass...
