The process of taking a snapshot of each field value in an object is a bit tricky. Reflection is used to walk through all the fields in the object. During this process, each field is checked to determine if it has the [NotUndoable()] attribute. If so, the field is ignored. The big issue is that field names may not be unique within an object. To see what I mean, consider the following two classes: public class BaseClass { int _id; } public class SubClass : BaseClass { int _id; } Here, each class has its own field named _id and in most circumstances, that s not a problem. However, when using reflection to walk through all the fields in a SubClass object, it will return two _id fields: one for each of the classes in the inheritance hierarchy. To get an accurate snapshot of an object s data, CopyState() needs to accommodate this scenario. In practice, this means prefixing each field name with the name of the class to which it belongs. Instead of two _id fields, the result is BaseClass!_id and SubClass!_id. The use of an exclamation point for a separator is arbitrary, but some character is necessary to separate the class name from the field name. As if this weren t complex enough, reflection works differently with classes that are subclassed from other classes in the same assembly, than with classes that are subclassed from classes in a different assembly. If in the example above, BaseClass and SubClass are in the same assembly, one technique can be used, but if they re in different assemblies, a different technique will be necessary. Of course, CopyState() should deal with both scenarios, so the business developer doesn t have to worry about these details.

Consider the following pseudo code that tries to do this without savepoints: Step 1: Log the message "beginning transaction at <timestamp>" Step 2: Do the transaction If there is an error then go to step 3 Otherwise go to Step 4 Step 3: Since a rollback will undo the changes done by Step 1, we do the following: Step 3a Redo the step 1 hopefully, we have saved the original timestamp Step 3b Log the transaction failure message Step 3c Commit and raise an exception Step 4: Log the transaction success message Step 5: Commit the transaction Notice how in the case of a transaction failure, we need to redo the work done by step 1 Now if we use savepoints, the pseudo code changes to the following: Step 1: Log the message "beginning transaction at <timestamp>" Step 2: Create a savepoint save_point1 Step 3: Do the transaction.

All classes are created automatically with a Class declaration, alias the classDeclaration method, and serve the following purpose: It specifies the scope and name of the class. It can specify that it extends another class. You can use it to declare class variables but not initialize them. New is the default constructor of the class where you can perform whatever initialization is required. Finalize is the destructor and is not invoked automatically, that is, you must explicitly invoke it on the class when you want to clean up. Your own methods fall into two categories: Object methods: Each instance of this object type has the method and they are invoked using the pattern myClass.myObjMethod(). Class methods: These are declared with the static keyword, and there is only one instance of such methods. They are called using a different notation from object methods, that is, myClass::myClassMethod(). If you define a Main method, you can call it from a menu item, and it is the only class or object method that can be called from a menu item. Note that if you have a 3-tier setup, then you should set classes to execute on the server as much as possible, as it's very costly for the AOS to retrieve them from the AOD and pass them to the client for execution.
