As briefly mentioned earlier in this chapter (and fully examined in 6), the has-a relationship allows us to compose new classes by defining member variables of existing classes. For example, assume you now have a Rectangle class, which makes use of the Point type to represent its upper-left/bottomright coordinates. Since automatic properties set all internal class variables to null, you will implement this new class using traditional property syntax: class Rectangle { private Point topLeft = new Point(); private Point bottomRight = new Point(); public Point TopLeft { get { return topLeft; } set { topLeft = value; } } public Point BottomRight { get { return bottomRight; } set { bottomRight = value; } } public void DisplayStats() { Console.WriteLine("[TopLeft: {0}, {1}, {2} BottomRight: {3}, {4}, {5}]", topLeft.X, topLeft.Y, topLeft.Color, bottomRight.X, bottomRight.Y, bottomRight.Color); } } Using object initialization syntax, you could create a new Rectangle variable and set the inner Points as follows: // Create and initialize a Rectangle. Rectangle myRect = new Rectangle { TopLeft = new Point { X = 10, Y = 10 }, BottomRight = new Point { X = 200, Y = 200} };

The whole ASP.NET application. May also be accessed by other applications. Fairly secure, because although data is never transmitted, it is stored in a database that could be compromised. Large amounts of data can be stored easily, but there may be a nontrivial overhead in retrieving and writing the data for each request. Store customer account information.

Again, the benefit of object initialization syntax is that it basically decreases the number of keystrokes (assuming there is not a suitable constructor). Here is the traditional approach to establishing a similar Rectangle: // Old-school approach. Rectangle r = new Rectangle(); Point p1 = new Point(); p1.X = 10; p1.Y = 10; r.TopLeft = p1; Point p2 = new Point(); p2.X = 200; p2.Y = 200; r.BottomRight = p2; While you might feel object initialization syntax can take a bit of getting used to, once you get comfortable with the code, you ll be quite pleased at how quickly you can establish the state of a new objectwith minimal fuss and bother. To wrap up this chapter, allow me to close with three bite-sized topics which will round out your understanding of building well encapsulated classes, specifically constant data, read only fields, and partial class definitions.

The DAO layer of the user manager example application consists of the UserDao interface, implemented by the UserDaoImpl class, which will deal directly with the XML file to retrieve and add users. Using the UserDao interface, you will be able to keep the same interface data type, even if you change the underlying DAO. For example, in 10, you will implement the same UserDao interface in your Hibernate DAO, so you won t need to adapt any classes that refer to the UserDao data types. To keep the application scalable and tidy, you will create two packages, as shown in Figure 9-7: The com.apress.usermanager.dao package will store all interfaces of the DAO layer. The com.apress.usermanager.dao.xml package will store all DAO implementation classes dealing with XML.

Clearly, there s no shortage of choices for managing state in ASP.NET! Fortunately, most of these state management systems expose a similar collection-based programming interface. The two exceptions are the query string (which is really a way of transferring information, not maintaining it) and profiles. This chapter explores all the approaches to state management shown in Table 6-1 and Table 6-2 but not those in Table 6-3. 11 covers caching, an indispensable technique for optimizing access to limited resources such as databases. 24 covers profiles, a higher-level model for storing userspecific information that works in conjunction with ASP .NET authentication. However, before you can tackle either of these topics, you ll need to have a thorough understanding of state management basics. In addition, you can always write your own custom state management code and use back-end server-side resources to store information. The most common example is one or more tables in a database. The drawback with using server-side resources is that they tend to slow down performance and can hurt scalability. For example, opening a connection to a database or reading information from a file takes time. In many cases, you can salvage these approaches by using caching to supplement your state management system. You ll explore your options for using and enhancing database access in Part 2.
