AbstractFactory Pattern

AbstractFactory模式用来解决这类问题：要创建一组相关或者相互依赖的对象。

AbstractFactory Pattern结构图

实现：

 1 #ifndef _PRODUCT_H_ 
 2 #define _PRODUCT_H_
 3 class AbstractProductA 
 4 { 
 5 public: 
 6     virtual ~AbstractProductA();
 7 protected: 
 8     AbstractProductA();
 9 private:
10 };
11 
12 class AbstractProductB 
13 { 
14 public: 
15     virtual ~AbstractProductB();
16 protected: 
17     AbstractProductB();
18 private:
19 };
20 
21 class ProductA1:public AbstractProductA 
22 { 
23 public: 
24     ProductA1();
25     ~ProductA1();
26 protected:
27 private:
28 }
29 
30 class ProductA2:public AbstractProductA 
31 {
32 public: 
33     ProductA2();
34     ~ProductA2();
35 protected:
36 private:
37 };
38 
39 class ProductB1:public AbstractProductB 
40 { 
41 public: 
42     ProductB1();
43     ~ProductB1();
44 protected:
45 private:
46 };
47 
48 class ProductB2:public AbstractProductB 
49 { 
50 public: 
51     ProductB2();
52     ~ProductB2();
53 protected:
54 private:
55 };
56 
57 #endif
