c++命名 (转)
匈牙利命名法规则
一般情况下,变量的取名方式为:
<scope_> + <prefix_> + <qualifier>。
范围前缀_,类型前缀_,限定词。
特殊的类型命名,前缀表示:
类、接口
|
前缀 |
类型 |
例子 |
备注 |
|
Lm |
Class |
LmObject |
表示类型本身 |
|
I |
Interface 接口 |
IUnknown |
注:类名前缀改为Lm,对于非全局的类最好有语义表示其所属模块。类的实例命名与类名大致相同,只是类名语义表示类的通用含义,而类名表示此实例的具体语义。如类名LmSketPoint表示草图点的类定义,而它的两个实例 _StartPoint,_EndPoint分别代表起点和终点的语义。类的实例命名带上前缀_。
特殊约定:
a. MouseTool的派生类的前缀为_Mt.
b. 对话框类的前缀为CDlg.
c. 橡皮条类的前缀为_Rb.
凡围前缀:

|
|
m_ |

注:编程时尽量少用全程变量,对于全程变量还应在类型前缀后加上如下关键字:
特征模块 : Fea
草图模块 : Sket
装配模块 : Asm
工程图模块: Lay
曲面模块 : Surf
界面模块 : Ui
