设计模式之C#实现(一)--AbstractFactory（补） |
|
|
|
|
|
|
GOF书中的例子用C#实现的源码：
using System;
namespace AbstractFactory_Maze{
using Maze;
public interface AbstractFactory{
MazeClass MakeMaze();
Wall MakeWall();
Room MakeRoom(int n);
Door MakeDoor(Room oneRoom,Room otherRoom);
}
public class MazeFactory : AbstractFactory{
public MazeClass MakeMaze(){
return new MazeClass();
}
public Wall MakeWall(){
return new Wall();
}
public Room MakeRoom(int n){
return new Room(n);
}
public Door MakeDoor(Room oneRoom,Room otherRoom){
return new Door(oneRoom,otherRoom);
}
}
// this is a client
public class MazeGame{
public MazeClass MazeCreate(AbstractFactory factory){
MazeClass aMaze = factory.MakeMaze();
Room r1 = factory.MakeRoom(1);
Room r2 = factory.MakeRoom(2);
Door aDoor = factory.MakeDoor(r1,r2);
aMaze.AddRoom(r1);
aMaze.AddRoom(r2);
r1.SetSide(Direction.North,factory.MakeWall());
r1.SetSide(Direction.East,aDoor);
r1.SetSide(Direction.South,factory.MakeWall());
r1.SetSide(Direction.West,factory.MakeWall());
r2.SetSide(Direction.North,factory.MakeWall());
r2.SetSide(Direction.East,factory.MakeWall());
r2.SetSide(Direction.South,factory.MakeWall());
r2.SetSide(Direction.West,aDoor);
return aMaze;
}
}
}
namespace Maze{
using System.Collections;
public class MapSite{
public virtual void Enter(){}
}
public enum Direction {North,South,East,West}
public class Room : MapSite{
public string Print(){
string result = "";
for(int i = 0 ;i |
