* Patterns : Proxy Structural Pattern
2007-11-12 10:13:00 Proxy Structural Pattern or Proxy object can be used in multiple ways. Some of them could be following : Act as a simpler interface to a complex object. Can be used to transform call from one format to another. can be used to load balance multiple objects. can be used to track concurrency or object numbers. Consider this example where a Proxy Calculator is acting as interface to Real Calculator. Client makes all calls to Proxy and proxy's responsibility is to route the calls both ways. This proxy template can be used to perform any of the above mentioned tasks with some modifications. Client is aware of only ProxyCalculator. public class ProxyCalculator : ICalculator { #region ICalculator Members RealCalculator rc; public ProxyCalculator() { ; rc = new RealCalculator(); } &#x...

* Patterns : Flyweight Structural Pattern
2007-11-06 06:32:00 Flyweight Structural Pattern is used to manage large number of shared objects. They are maintained in a collection and same instances used whenever required. These objects have their own attributes/features but they can have a common feature also which can be externalized. Consider a scenario where a picture has to be drawn which consists of large numbers of polygons of different colors. All polygons have number of sides property which is very specific to them but all of them have a common property called color which can be externalized. Also for same polygon type like 'Square', number of sides remain same but color may change. Flyweight pattern helps in managing such kind of scenarios. Polygon factory manages the collection of polygons. Each concrete polygon stores number of sides but the color property is taken at runtime. Same instance of polygon can be used to draw any number of times with different color. The client code is following : namespace FlyWeight ... More About: Tutorials , Architecture , Sharp , Patterns

* Troubleshooting : Client Certificate Authentication
2007-10-25 12:06:00 You are doing a setup for Client Certificate Authentication for your web application. The client and server tools involved are : Internet Explorer 6 or 7 IIS 6.0 Windows 2003 After installing client and server certificates and enabling 'Accept Certificates' at IIS end, you may face one of these problems: You are not able to verify whether the client certificate is currently installed for 'Client Authentication' in my browser because 'Intended purpose' doesn't show 'Client Authentication' When I try to access the site which accepts client certificates, I get a popup in browser to select the client certificate but it does not list my browser certificate. Here are some things you can check: To get the 'Client Authentication' in 'Intended Purpose' drop down. Click 'Advanced..' button and uncheck 'Client Authentication'. Make sure that the CA of the client certificate is added to 'Trusted Root Certification Authorities' directory of web... More About: Security , Troubleshooting , Shoot

* Patterns : Facade Structural Pattern
2007-10-18 12:39:00 'Facade Structural Pattern ' is primarily used to unify and simply a set of interfaces of subsystems. This helps the client in using the interface with less effort. Consider the class diagram below : Above shows a typical scenario of a Bank where a new Customer approaches the Bank to open new account and also deposit some initial amount. The Core Banking subsystems provide two different interfaces for Customer and Account and two different calls are required for Account opening and deposit of amount. The Bank Facade shown above simplifies the new Customer creation, new Account Creation and deposit amount by providing a single interface/call to perform the required actions. The Bank facade has following code : // Acts as Facade public class Bank { Customer cust; Account acct; public void CreateCustomer(string name, string address, double initalDeposit) { ...

* Patterns : Decorator Structural Pattern
2007-10-15 12:22:00 The primary use of 'Decorator Structural Pattern ' is to add behaviors to object at runtime. It generally involves wrapping the original object with the decorator object which adds the new behaviors but keep the structure of original object intact. Multiple behaviors can be added out of given options based on decision criteria. Consider the class diagram below : There is a BookBase class which is extended based on subjects of books and types of books. FictionBook subclasses BookBase based on subject/category while VideoBookBase subclasses BookBase based on type of book. Now BookBase has a method called DisplayInfo() which is used to display about book. If DisplayInfo is called on FictionBook object it will display only the properties which are common to all display books, but suppose the fiction book is a video book and the DispayInfo should also display the duration, we use the above pattern as below : The client code looks like following : public class Client ...

* Patterns : Composite Structural Pattern
2007-10-09 06:38:00 Composite Structural Pattern is applicable when you need to deal with whole-part kind of relationships or tree kind of structures. It helps client to deal with individual or composite objects in a uniform manner and thus abstracts the client from complexities of internal structure. Consider the following class diagram : In the above diagram Book is a simple type but LibrarySection is a complex type and is composed of Book type instances. But both have same base which is BookBase and so both the simple type and composite type have same methods exposed to client. The client code will look like following : public class Client { Book cSharp Book,vbBook,historyBook,religion; LibrarySection techBooks, nonTechBooks, library; public void Run() { ; cSharpBook = new Book("CSharp Book"); ...

* Patterns : Bridge Structural Pattern
2007-10-05 07:24:00 Bridge Structural Pattern decouples an abstraction from its implementation so that the two can vary independently. Multiple variants of abstraction can be created provided they implement the common interface. Similarly, multiple variants of implementations can be created provided they implement the common interface. Given the option of multiple abstraction variants and multiple implementation variants, clients have the flexibility of using any abstraction class with any implementation. Consider the class diagram below : There is one variant of abstraction called AbstractionX and two variants of implementation ImplementationA and ImplementationB. The client code looks like following : public class Client { AbstractionBase absBase; public void Run() { ; ImplementationA implA = new ImplementationA(); ...

* Patterns : Adapter Structural Pattern
2007-10-03 10:10:00 Adapter pattern also called as Wrapper pattern lets client adapt a framework/service with different call definitions than what client has been designed for. Clients continue using the original definitions and adapter takes care of transformation. Consider the class diagram below : Client calls the ClientBase class which is client's default framework. Now Client is supposed to use FrameworkBase which has Print method instead of PrintString method. Now instead of changing the client, an Adapter class is created which take care of transforming the method calls. Provided the methods in ClientBase are virtual, Adapter class can use ClientBase class as base class to provide the transformation functionality. public class Adapter : ClientBase { private FrameworkBase frmkBase; public Adapter() { ; frmkBase = new FrameworkBase(); } ...

* Singleton Creational Pattern
2007-09-28 06:40:00 One of the most popular creational pattern. It is used to restrict the number of instances of a type to one and so all clients use the same instance. Consider the following class diagram : Client creates two variables of type Singleton, s1 and s2. The client code looks like following : public class Client { Singleton s1,s2; public void Run() { // s1 = new Singleton(); // new cannot be called. s1 = Singleton.GetInstance(); s1.ID = 999; s2 = Singleton.GetInstance(); Console.WriteLine("ID = " + s2.ID); } }The output of s2.ID is '999' which shows that both s1 and s2 are referring to same instance of Singleton. Also note that default constructor has been protected.The code for actual 'Singleton' class looks like following : public class Singleton { public int ID; private static Singleton Instance; // Constructor is protected so that new cannot be cal...

* Patterns : Prototype Creational Pattern
2007-09-24 09:19:00 Prototype Creational Pattern provides an interface which can be used by client to get access to already existing instance of a type which can be used as prototype by client to create new instance. Client can clone the existing object using deep or shallow copy and use it. It is used mainly when inherent cost of creating a new object is high. Consider the following class diagram : Above scenario goes like this : Client needs the updated list of managers. ListAdmin can provide the list but its not latest. Now, client instead of creating the list from scratch which can be very resource consuming, picks the list from ListAdmin, creates a shallow copy of it and updates it for further use. public class Client { public static void Run() { ManagersList managersList = ListAdmin.getManagersList(); Console.WriteLine("Printing managersList ...."); DisplayList(managersList); ManagersList list = (ManagersList)managersList.Clone();...

* Patterns : Factory Method Creational Pattern
More articles from this author:2007-09-24 06:46:00 It provides an interface for creating an object but lets subclass decide which class to instantiates. So, it can also be called as virtual constructor. Consider the following class diagram : ShapeCreator class provides an factory method to create objects of BaseShape. Client always uses ShapeCreator and BaseShape type variables to work on instances of derives classes. The client looks like following : public class Client { ShapeCreator createsShape; public void Run() { BaseShape shape; createsShape = new CircleCreator(); shape = createsShape.CreateShape(); shape.WhoAmI(); } }The code of CircleCreator looks like following : public class CircleCreator : ShapeCreator { public override BaseShape CreateShape() { return new CircleShape(); } }The CircleCreator decides which class to instantiate in response to CreateShape() method.Download full source code from here : ...
