Detailed operation steps for embedding Python into C ++ Operator Overloading

Embed Python into the operator overloading of C ++. If you overload related operators in C ++. when Python is passed to Python, You can overload the "+" operator of the Msg class by using the following code. def (self + self) "is passed to Python.

 
 

  
  
class Msg:public Message  
  
  
{  
  
  
public:  
  
  
int count;  
  
  
Msg(std::string m):Message(m)  
  
  
{  
  
  
}  
  
  
void setcount(int n)  
  
  
{  
  
  
count = n;  
  
  
}  
  
  
int getcount()  
  
  
{  
  
  
return count;  
  
  
}  
  
  
int operator+ (Msg x) const  
  
  
{  
  
  
int r;  
  
  
r = count + x.count;  
  
  
return r;  
  
  
}  
  
  
};  
  
  
BOOST_PYTHON_MODULE(Message)  
  
  
{  
  
  
class_<Message>("Message",init<std::string>())  
  
  
.add_property("msg",&Message::get,&Message::set);  
  
  
class_<Msg, bases<Message> >("Msg",init<std::string>())  
  
  
.def("setcount", &Msg::setcount)  
  
  
.def("getcount", &Msg::getcount)  
  
  
.def(self + self);  
  
  
}  
 
 

You can use the same method to embed Python into the operator overload of C ++, as shown below.

. Def (self-self) // equivalent to the _ sub _ Method

. Def (self * self) // equivalent to the _ mul _ Method

. Def (self/self) // equivalent to the _ div _ Method

. Def (self <self); // equivalent to the _ lt _ Method

The above is an introduction to the content related to the heavy loading of operators embedded in Python C ++. I hope you will gain some benefits.
