用C++实现类似JAVA类中的toString函数

最近在开发时，发现C++的类中没有JAVA类中toString函数，打印对象的信息十分麻烦，就用宏自己实现了一个

主要代码如下

#define PRINT_CLASS_INFO_BEGIN(sstream, className) sstream << "ClassName:" << #className << ", Addr:" << this << "[";

#define PRINT_CLASS_PARA(sstream, para) sstream << #para << " = " << para;

#define PRINT_CLASS_INFO_END(sstream) sstream << "]" << std::endl;

class MyClass

{

public:

virtual string toString();
private:

int m_iPara1;
string m_strPara2;
}

string MyClass::toString

{

stringstream sstream;

PRINT_CLASS_INFO_BEGIN(sstream, MyClass)
PRINT_CLASS_PARA(sstream, m_iPara1)
PRINT_CLASS_PARA(sstream, m_strPara2)
PRINT_CLASS_INFO_END(sstream)

return sstream.str();
}
