我个人实现的C++之get和set方法，使用宏定义

#pragma once
//PropertyBuilderByTypeName 用于生成类的成员变量
//并生成set和get方法
//variable_type为变量类型,可以是指针类型,也可以是非指针类型,例如int,int*等
//type_shortname为变量类型的缩写,例如bool缩写为b,int缩写为i,double缩写为d等
//method_name为方法名称
//access_permission为变量的访问权限(public, protected, private)
#define PropertyBuilder_ReadWrite(variable_type, type_shortname, method_name, access_permission)\
access_permission:\
    variable_type m_##type_shortname##method_name;\
public:\
    inline variable_type get##method_name(void)\
    {\
        return m_##type_shortname##method_name;\
    }\
    inline void set##method_name(variable_type v)\
    {\
        m_##type_shortname##method_name = v;\
    }\
#define PropertyBuilder_ReadOnly(variable_type, type_shortname, method_name, access_permission)\
access_permission:\
    variable_type m_##type_shortname##method_name;\
public:\
    inline variable_type get##method_name(void) const\
    {\
        return m_##type_shortname##method_name;\
    }\
#define PropertyBuilder_WriteOnly(variable_type, type_shortname, method_name, access_permission)\
access_permission:\
    variable_type m_##type_shortname##method_name;\
public:\
    inline void set##method_name(variable_type v)\
    {\
        m_##type_shortname##method_name = v;\
    }\

class MyClass
  {
  public:
  MyClass()
  {
    m_bLookAhead = true;
    m_dStatus = NULL;
    m_iHello = 0;
  }
  ~MyClass() {}
  PropertyBuilder_ReadWrite(bool, b, LookAhead, protected)//bool m_bLookAhead;
  PropertyBuilder_ReadWrite(double*, d, Status, protected)//bool* m_pStatus;
  PropertyBuilder_WriteOnly(int, i, Hello, private)//int m_iHello;
  public:
  void test()
  {
    setLookAhead(true);
    double a = 0;
    setStatus(&a);
    setHello(5);
    bool r = getLookAhead();
  }
  };
