原型模式

【1】什么是原型模式？

原型模式即复制，或者克隆模式。

【2】原型模式代码示例：

代码示例1：

 1 #include <iostream>
 2 #include <string>
 3 using namespace std;
 4 
 5 class Prototype
 6 {
 7 private:
 8     string str;
 9 public:
10     Prototype(string s)
11     {
12         str = s;
13     }
14     Prototype()
15     {
16         str = "";
17     }
18     void show()
19     {
20         cout << str << endl;
21     }
22     virtual Prototype *clone() = 0;
23 };
24 
25 class ConcretePrototype1 : public Prototype
26 {
27 public:
28     ConcretePrototype1(string s) : Prototype(s)
29     {}
30     ConcretePrototype1(){}
31     virtual Prototype *clone()
32     {
33         ConcretePrototype1 *p = new ConcretePrototype1();
34         *p = *this;
35         return p;
36     }
37 };
38 
39 
40 class ConcretePrototype2 : public Prototype
41 {
42 public:
43     ConcretePrototype2(string s) : Prototype(s)
44     {}
45     ConcretePrototype2(){}
46     virtual Prototype *clone()
47     {
48         ConcretePrototype2 *p = new ConcretePrototype2();
49         *p = *this;
50         return p;
51     }
52 };
53 
54 int main()
55 {
56     ConcretePrototype1 *test = new ConcretePrototype1("小李");
57     ConcretePrototype2 *test2 = (ConcretePrototype2 *)test->clone();
58     test->show();
59     test2->show();
60     return 0;
