C++用宏定义实现PROPERTY

#define PROPERTY_RW(T,var) public: \
void set_##var(const T& _var){m_##var=_var;}\
T get_##var(){return m_##var;}\
private: T m_##var;

class Test
{
public:
	Test();
	~Test();
	PROPERTY_RW(int, my_var)
private:

};

Test::Test()
{
}

Test::~Test()
{
}

int main()
{
	Test t;
	t.set_my_var(1000);
	auto x=t.get_my_var();
	printf("var=%d\n", x);
	getchar();
    return 0;
}
