Instead of defining your own enum for the levels, you are using the syslog-defined levels. The code for this is pretty straightforward. You could modify this code to be able to handle any output you wanted, and these side effects would be invisible to the OCaml code that calls it.

Android allows you to define custom permissions with your application. For example, if you wanted to prevent certain users from starting one of the activities in your application, you could do that by defining a custom permission. To use custom permissions, you first declare them in your AndroidManifest.xml file. Once you ve defined a permission, you can then refer to it as part of your component definition. We ll show you how this works. Let s create an application containing an activity that not everyone is allowed to start. Instead, to start the activity, a user must have a specific permission. Once you have the application with a privileged activity, you can write a client that knows how to call the activity. First, create the project with the custom permission and activity. Open the Eclipse IDE and select New New Project Android Project. This will open the New Android Project dialog box. Enter CustomPermission as the project name, select the Create new project in workspace radio button, and mark the Use default location check box. Enter Custom Permission as the application name, com.cust.perm as the package name, CustPermMainActivity as the activity name, and select a Build Target. Click the Finish button to create the project. The generated project will have the activity you just created, which will serve as the default (main) activity. Let s also create a so-called privileged activity an activity that requires a special permission. In the Eclipse IDE, go

to the com.cust.perm package, create a class named PrivActivity whose superclass is android.app.Activity, and copy the code shown in Listing 7 4.

Android 1.1 test harness that we built in 10. By simply adding the AbstractRenderer to the classes in 1.5, you will arrive at the equivalent of the 10 test harness. You can use this resulting 1.5 test harness for most of your beginning needs. As you become more skilled with OpenGL, you can derive classes similar to AbstractRenderer as necessary. Or you can just ignore the AbstractRenderer and implement that functionality directly in the class you derive from the Renderer.

Inheritance isn t the only way to provide functionality in a class; you can also use composition. Composition is when you have a class that has some feature (instead of being some feature). If you refer to the extended_random number class from the inheritance examples, there is an example of composition. You will define a new class that uses composition instead of inheritance to provide functionality. The extended_random class provides a new method that mimics a single die with an arbitrary number of sides. The new class (using composition) uses this class to provide a craps simulation.

public class PrivActivity extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); LinearLayout view = new LinearLayout(this); view.setLayoutParams(new LayoutParams( LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT)); view.setOrientation(LinearLayout.HORIZONTAL); TextView nameLbl = new TextView(this); nameLbl.setText("Hello from PrivActivity"); view.addView(nameLbl); setContentView(view); } }
