Let s now discuss how we can implement the above requirements. To enforce a common standard for report delivery, you can lay out the following rules: Each custom extension type must expose a method that the Report Server will invoke to distribute the report. This method must have at least one argument that the Report Server will use to pass the report notification object. Given the above specifications, figure 15.1 shows how two custom delivery extensions could be implemented. Let s say that the first extension supports report delivery to a printer similarly to the sample that comes with RS, while the second can be used to distribute reports to a Web service. In the first case, you ve decided to encapsulate the delivery logic in a method called Deliver, while in the latter, in a method called Distribute. Once the custom extensions are registered with the Report Server, you can define subscriptions that use these extensions, as we discussed in chapter 14. During runtime, the Report Server will instantiate the appropriate extension and delegate the report delivery to it. Everything looks great! Or does it 15.1.2 Working with interface inheritance Upon further inspection, several issues surface. First, the Report Server has to know beforehand not only the type name of the extension but also the name of the method responsible for the report delivery. One possible workaround would be to save the method name in the configuration file too, but this will present a maintenance issue. Another solution would be to change the specification and stipulate that all delivery methods must have the same name, for example, Deliver. However, this approach

Although you will sometimes see the layers of the TCP/IP model assigned their own numbers independent of the OSI model, this book s terminology reflects the layer number usage that is far more current.

Figure 15.1 Without interfaces, it is difficult to achieve standardization. For example, this figure shows two possible implementation approaches to implement custom delivery extensions. Because they don t follow a single standard, it is difficult for the Report Server to integrate them.

Layer 2, also called the Network Interface Layer or Data Link Layer, is the step in the communication process that describes a specific set of standards for network adapters, hardware addresses (such as MAC addresses) assigned to those adapters, cabling type, hubs, switches, associated physical standards, and associated messaging protocols. The function of this layer is to deliver messages from one device to the next, and its protocols allow communications to occur between computers separated only by hubs, switches, and cabling. Examples of standards defined at the Network Interface Layer include Ethernet and Token Ring.

is not easily enforceable, especially by people who are as opinionated and strong-willed as developers tend to be. Second, the Report Server won t be able to easily inspect the signature of the delivery method in advance to check to see if it follows the specification. For example, what if the developer has neglected to specify an argument for the notification object This will certainly result in a runtime exception. Finally, there is no easy way for the Report Server to invoke the delivery method. Interface inheritance The above issues can be easily overcome by using interface inheritance. At this point, you may be curious as to what an interface really is. We can loosely define an interface as a set of methods, properties, and events that define an object s characteristics and behavior. You define an interface similarly to the way you define a class. For example, in the above scenario, this is what the delivery extension interface may look like in C#:

If you are designing a network for a given number of computers, you might have to determine an appropriate subnet mask for that network. For example, if you are building a new departmental local area network (LAN) with 20 computers that will be connected to the corporate network, you need to plan for that LAN by requesting a /27 or larger address block from a network engineer in charge of addressing in your company. (This is because a /27 network can accommodate 32 addresses and 30 computers.) The network engineer can then assign you a block such as 10.25.0.224/27 within a larger address space, such as 10.0.0.0 /8 used by the corporate network. To determine block size requirements in terms of a subnet mask, first determine the number of addresses needed by adding two to the number of computers. Then, you can use the halving-and-doubling technique to find the smallest address block that can accommodate your network requirements.
