This article introduces the operation procedure of operator overloading of embedding Python into C++. The content is very detailed. Interested friends can use it for reference. I hope it will be helpful to you.

Embed Python into the operator overload of C++ if you overload the related operator in C++ and pass Boost.Python to Python, you can overload the "+" operator of the Msg class and pass it to Python through ".def (self + self)" in the following code.

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", init ()) .add _ property ("msg", & Message::get,&Message::set); class_ ("Msg", init ()) .def ("setcount", & Msg::setcount) .def ("getcount", & Msg::getcount) .def (self + self);}

Embedding Python in C++ 's operator overloading works the same way for other operator overloads, 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

This is the end of the procedure for embedding Python into C++ 's operator overloading. I hope the above can be of some help and learn more. If you think the article is good, you can share it for more people to see.
