Implement "GOF's Bridge pattern" Using C++(Series of Gof patterns using C++ 3rd article)

The Gof has 23 design patterns , but in most of  the design books , the E.G is written in Java , So  from now on , I will write about 23 articles to implement them using C++ , the design pattern itself is discussible , so welcome everyone to give his excelent idea to me , My QQ: 286259397 And My MSN : [email protected].
Welcome every one to express his ideas!

 

This is the  Third Arcticle:  Bridge PATTERN

The Bridge pattern separate the impelment part  and the abstract part , so that they can variant each other



                                 3.1          Bridge -Pattern  UML Diagram
Referring the UML , The C# Codes goes Here:

 1namespace BridgeDesignPattern
 2{
 3    abstract class TSquare
 4    {
 5        public abstract void OnKey();
 6        public abstract void Conflict();
 7        public abstract void Glitter();
 8    };

10    class TSquareHole : TSquare
11    {

16        }
17        public override void OnKey()
18        {
19            _imp.OnKey();
20        }

22        {
23            _imp.Conflict();
24        }
25        public override void Glitter()
26        {
27            _imp.Glitter();
28        }
29    };

43
44        }

46        {
47            Console.WriteLine("TPCSquareHoleImp Conflict");
48        }
49        public override void Glitter()
50        {
51            Console.WriteLine("TPCSquareHoleImp Glitter");
52        }
53    };
54    class TMobileSquareHoleImp:TSquareImp
55    {
56            public override void OnKey()
57            {

59
60            }

69    };
            

  static   void  Main( string [] args)
            {
                  BridgeDesignPattern.TMobileSquareHoleImp _imp = new BridgeDesignPattern.TMobileSquareHoleImp();
                  BridgeDesignPattern.TSquareHole _hole = new BridgeDesignPattern.TSquareHole(_imp);
                  _hole.OnKey();

               Console.Read();
        }
