In 9, you learned how to implement the IComparable interface in order to compare the relationship between two like objects. You can, in fact, also overload the comparison operators (<, >, <=, and >=) for the same class. As with the equality operators, C# demands that if you overload <, you must also overload >. The same holds true for the <= and >= operators. If the Point type overloaded these comparison operators, the object user could now compare Points as follows: // Using the overloaded < and > operators. static void Main(string[] args) { ... Console.WriteLine("ptOne < ptTwo : {0}", ptOne < ptTwo); Console.WriteLine("ptOne > ptTwo : {0}", ptOne > ptTwo); Console.ReadLine(); } Assuming you have implemented the IComparable interface, overloading the comparison operators is trivial. Here is the updated class definition: // Point is also comparable using the comparison operators. public class Point : IComparable { ... public int CompareTo(object obj) { if (obj is Point) { Point p = (Point)obj; if (this.X > p.X && this.Y > p.Y) return 1; if (this.X < p.X && this.Y < p.Y) return -1; else

Creating a basic chat application is a good way to understand how to use the Flex mx.Producer and mx.Consumer components to exchange real-time messages using the BlazeDS server. Although the example just exchanges simple text messages, you can apply the same implementation and configuration techniques to an application that exchanges more complex objects, such as data model entity objects. In order to create the chat application example, you need to create a Maven project that contains the BlazeDS dependencies. Then you need to create the BlazeDS configuration files in order to configure the channels and adapters for working with real-time messages. When you are happy with your server setup, you can create a simple Flex project using just MXML application classes containing the mx.Consumer and mx.Producer components, and TextArea and TextInput components, in order to send and receive messages.

The number of items in the current session collection. Identifies whether this session is tracked with a cookie or with modified URLs. Identifies whether this session was just created for the current request. If there is currently no information in session state, ASP.NET won t bother to track the session or create a session cookie. Instead, the session will be re-created with every request. Provides an enumerated value that explains how ASP.NET stores session state information. This storage mode is determined based on the web.config configuration settings discussed later in this chapter. Provides a string with the unique session identifier for the current client. Provides a collection of read-only session items that were declared by <object runat=server> tags in the global.asax. Generally, this technique isn t used and is a holdover from ASP programming that is included for backward compatibility. The current number of minutes that must elapse before the current session will be abandoned, provided that no more requests are received from the client. This value can be changed programmatically, giving you the chance to make the session collection longer term when required for more important operations. Cancels the current session immediately and releases all the memory it occupied. This is a useful technique in a logoff page to ensure that server memory is reclaimed as quickly as possible. Removes all the session items but doesn t change the current session identifier.

Like any C# programming element, overloaded operators are represented using specific CIL syntax. To begin examining what takes place behind the scenes, open the OverloadedOps.exe assembly using ildasm.exe. As you can see from Figure 12-1, the overloaded operators are internally expressed via hidden methods (such as op_Addition(), op_Subtraction(), op_Equality(), and so on).

Now, if you were to examine the specific CIL instructions for the op_Addition method (the one that takes two Point parameters), you would find that the specialname method decoration has also been inserted by the compiler: .method public hidebysig specialname static class OverloadedOps.Point op_Addition(class OverloadedsOps.Point p1, class OverloadedOps.Point p2) cil managed { ... } The truth of the matter is that any operator that you may overload equates to a specially named method in terms of CIL. Table 12-2 documents the C# operator-to-CIL mapping for the most common C# operators. Table 12-2. C# Operator-to-CIL Special Name Road Map
