Since we have recently built a marking language, let s stick with the quiz example. Quizzes need questions, so we build a Question class, giving it a mark() method. All is well until we need to support different marking mechanisms. Let s say that we are asked to support the simple MarkLogic language, marking by straight match and marking by regular expression. Your first thought might be to subclass for these differences, as in Figure 11-3.

3. Blind casts are also known as hard casts, or unchecked casts. It s largely a matter of taste but I don t think that hard really implies unchecked, and I prefer to use the positive blind cast to the negative unchecked cast.

Figure 1-10. Selecting the Permission Levels option The Permission Levels page shown in Figure 1-11 lists the permission levels that have been defined. Notice that you cannot access the Full Control and Limited Access permission levels, because these levels must always exist, and their definitions cannot change. The Full Control level belongs to site owners. The Limited Access level belongs to site guests who only have limited access to specific lists or documents libraries, not the entire site. Suppose you decide to add a new permission level called Approver. Click the Add a Permission Level menu option near the top of the page to display the page shown in Figure 1-12. The first section asks you to provide a name and description for the new level. Then you can select from the possible permissions. SharePoint splits permissions into three major groups: List Permissions: Permissions related to list objects, including libraries Site Permissions: Permissions related to sites Personal Permissions: Permissions related to personalization

Figure 11-3. Defining subclasses according to marking strategies This would serve us well as long as marking remains the only aspect of the class that varies. Imagine, though, that we are called on to support different kinds of questions: those that are text based and those that support rich media. This presents us with a problem when it comes to incorporating these forces in one inheritance tree as you can see in Figure 11-4.

That is, a .NET application can never scramble its memory by treating This type of object as if it were That unrelated type of object.4 One whole large class of difficult bugs has been wiped out, simply by disallowing blind casts. As with Delphi s as cast, the cost of doing the check is relatively modest calling a subroutine that reads the 32-bit class type from the object, and compares that type (and, perhaps, ancestral types) to a constant and the cost of raising an exception is basically irrelevant next to the value of having execution stop before you do any damage.
