在C++中,序列化是将对象状态转换为可以存储或传输的格式的过程。反序列化是将这种格式还原为对象状态的过程。当涉及到脚本语言交互时,序列化和反序列化可以实现C++代码与脚本语言之间的数据传递。
以下是一个使用C++序列化库(如Boost.Serialization)与Python脚本语言交互的示例:
cmake_minimum_required(VERSION 3.10)
project(cpp_serialization)
set(CMAKE_CXX_STANDARD 14)
find_package(Boost REQUIRED COMPONENTS serialization)
include_directories(${Boost_INCLUDE_DIRS})
add_executable(cpp_serialization main.cpp)
target_link_libraries(cpp_serialization ${Boost_LIBRARIES})
// my_class.h
#pragma once
#include <boost/serialization/access.hpp>
#include <boost/serialization/nvp.hpp>
class MyClass {
public:
int x;
float y;
private:
friend class boost::serialization::access;
template<class Archive>
void serialize(Archive & ar, const unsigned int version) {
ar & BOOST_SERIALIZATION_NVP(x);
ar & BOOST_SERIALIZATION_NVP(y);
}
};
// main.cpp
#include <fstream>
#include <boost/archive/binary_oarchive.hpp>
#include "my_class.h"
int main() {
MyClass obj;
obj.x = 42;
obj.y = 3.14f;
std::ofstream ofs("data.bin", std::ios::binary);
boost::archive::binary_oarchive oa(ofs);
oa << obj;
return 0;
}
import ctypes
class MyClass(ctypes.Structure):
_fields_ = [
("x", ctypes.c_int),
("y", ctypes.c_float)
]
with open("data.bin", "rb") as f:
data = f.read()
obj = MyClass()
ctypes.memmove(ctypes.addressof(obj), data, ctypes.sizeof(obj))
print("x:", obj.x)
print("y:", obj.y)
注意:这个示例仅适用于简单的C++类,不包含指针、引用等复杂数据结构。对于更复杂的类,可能需要自定义序列化和反序列化函数以适应不同的脚本语言。
