Now that you ve defined the extension, you need to create the class you specified in the extension Create the class

If a client calls a method on a field or variable that is null, an exception may be raised, a system may crash, or similar problems may occur To protect our systems from such unwanted behavior, we write checks to prevent null fields or variables from being called and, if necessary, specify alternative behavior to execute when nulls are encountered: if (someObject != null) someObjectdoSomething(); else performAlternativeBehavior();

The LabelProvider class contains two methods that you will override: getImage and dispose Using the getImage method, you can specify your own icon and description instead of using the defaults (see Figure 143 earlier) Fill in the details of the class as shown in Example 145 You will associate the icon soapbindinggif with the WTP SOAP binding element This icon is available from the examples package from this book s accompanying Web site

Repeating such null logic in one or two places in a system isn't a problem, but repeating it in multiple places bloats a system with unnecessary code Compared with code that is free of null logic, code that is full of it generally takes longer to comprehend and requires more thinking about how to extend Null logic also fails to provide null protection for new code So if new code is written and programmers forget to include null logic for it, null errors can begin to occur [1] The Null Object pattern provides a solution to such problems It removes the need to check whether a field or variable is null by making it possible to always call the field or variable safely The trick is to assign the field or variable to the right object at the right time When a field or variable can be null, you can make it refer to an instance of a Null Object, which provides do-nothing, default, or harmless behavior Later, the field or variable can be assigned to something other than a Null Object Until that happens, all invocations safely route through the Null Object

Before we get to the code, con guration, and processes for implementing secure services, let s begin by introducing four major tenets of service security: authentication, authorization, con dentiality, and integrity With those de ned, we ll then describe the concepts of transport and message security as they apply to WCF

Bruce Anderson aptly named this patternactive nothing [Anderson] because a Null Object actively performs behavior that does nothing Martin Fowler described how a Null Object is an example of a broader pattern called Special Case [Fowler, PEAA] Ralph Johnson and Bobby Woolf described how null versions of patterns like Strategy [DP], Proxy [DP], Iterator [DP], and others are often used to eliminate null checksWoolf] [
