set / get in c ++。 [英] set/get in c++.
问题描述
嗨。
为了减少标题的大小并加入
变量的定义和内联函数的定义，我使用宏i看到
这个组包含所有内置类型和类型的赋值运算符。
#define ATRIBUTO（type，x）\
私人：\
类型x; \
公开：\
类型&获取## x（）{return x; } \
类型获取## x（）{return x; } const \
void设置## x（类型值）{x =值; } \
A级{
ATRIBUTO（char，caracter）;
};
1.-这个宏可能有缺陷吗？
2.-是否有任何解决方法，以便功能名称
扩展为名称在设置或获取资金后的第一个字母？，我
意味着：
GetCaracter和SetCaracter而不是Getcarater和Setcaracter。
我想在会员中使用caracter而不是Caracter
函数A.
提前谢谢你，原谅我的英文不好。

这是正式的我见过的这个
组中最糟糕的一个想法。

这样更好。
A级

字符;

但这非常糟糕，你的版本非常非常糟糕。我认为你需要
在面向对象的设计中做一些修改。

我同意他的宏是丑陋（和坏代码），但我不确定是否有任何内在错误的get / set方法。我经常发现它们
非常有用。
当get / set方法与实现相关时出现问题
详细信息一对一的基础（如在宏观中）。

Hi.
In order to reduce the size of my headers and join definitions of
variables and definitions of inline functions, i use a macro i saw in
this group for all built-in types and types with assignment operator.
#define ATRIBUTO( type, x) \
private: \
type x; \
public: \
type & Get##x() { return x; } \
type Get##x() { return x; } const \
void Set##x( type value ) { x = value; } \
class A{
ATRIBUTO(char, caracter);
};
1.- Can be flawed this macro?.
2.- Is there any workaround so that the names of the functions are
expanded to a name with the first letter following Set or Get capital?, i
mean:
GetCaracter and SetCaracter instead of Getcarater and Setcaracter.
I want to use caracter rather than Caracter inside the member
functions of A.
Thank you in advance and excuse my bad english.解决方案Manzanita wrote:

This is officially one of the worst ideas I''ve ever seen posted on this
group.

This is better.
class A
{
public:
char character;
};
but this is very bad and your version is very, very bad. I think you need to
do some revision in object oriented design.

I agree that his macro was ugly (and bad code), but I''m not sure there''s
anything intrinsically wrong with get/set methods. I often find them
quite useful.
The problem comes when the get/set methods are tied to implementation
details on a one-to-one basis (like in the macro).
