Patterns in SOME –Builder

Code in C#:

 namespace Builder_DesignPattern

{

     using System;

 

     // These two classes could be part of a framework,

     // which we will call DP

     // ===============================================

    

     class Director

                   abstractBuilder.BuildPartB();            

              }

              abstractBuilder.BuildPartC();            

         }

 

     }

 

     abstract class AbstractBuilder

     {

         abstract public void BuildPartA();

         abstract public void BuildPartB();

         abstract public void BuildPartC();

     }

 

     // These two classes could be part of an application

     // =================================================

 

     class ConcreteBuilder : AbstractBuilder

     {

         override public void BuildPartA()

         {

              // Create some object here known to ConcreteBuilder

              Console.WriteLine("ConcreteBuilder.BuildPartA called");

         override public void BuildPartB()

         {

         {

              Console.WriteLine("ConcreteBuilder.BuildPartC called");

         }

     }

Code in SOME:

  

CDirector

       Construct(AAbstractBuilder)

      

AAbstractBuilder

       a_BuildPartA()

       a_BuildPartB()

       a_BuildPartC()

 

CConcreteBuilder: AAbstractBuilder

       o_BuildPartA()

       o_BuildPartB()

       o_BuildPartC()

 

CClient

       main

      

CClient.main

{

       CConcreteBuilder concreteBuilder.();

       CDirector director.();

       director.Construct(concreteBuilder)

       {

              concreteBuilder.BuildPartA<CConcreteBuilder>()

              {

                     <% /*("CConcreteBuilder.BuildPartA called")*/ %>

              };

              concreteBuilder.BuildPartB<CConcreteBuilder>()

              {

                     <% /*("CConcreteBuilder.BuildPartA called")*/ %>

              };

              concreteBuilder.BuildPartC<CConcreteBuilder>()

              {

                     <% /*("CConcreteBuilder.BuildPartA called")*/ %>

              };

       };
