The _bindingEdit field is used to determine whether the BeginEdit() method has been called already so any subsequent method calls can be ignored The _bindingEdit field is set to true when an edit process is started and to false when either CancelEdit() or ApplyEdit() is called The _neverCommitted field tracks whether the ApplyEdit() method has ever been called If it hasn t ever been called, and data binding attempts to cancel the edit operation, this flag is used to control whether the object should remove itself from its parent collection The _neverCommitted field starts out true and is set to false if ApplyEdit() is called With this mechanism in place, the implementation of IEditableObjectBeginEdit() calls only the real BeginEdit() method if no edit session is currently underway With the implementation of.

the n-level undo methods and System.ComponentModel.IEditableObject, business objects now provide full control over editing and undo capabilities, both to the UI developer and to Windows Forms data binding.

2 introduced the idea that a business object can be a root, parent, and/or child object. A definition of each can be found in Table 3-7. Table 3-7. Root, Parent, and Child Definitions

The other part of the equation for understanding the pluggable storage engine interface is the handler class. The handler class is derived from Sql_alloc, which means that all of the memory allocation routines are provided through inheritance. The handler class is designed to be the implementation of the storage handler. It provides a consistent set of methods for interfacing with the server via the handlerton structure. The handlerton and handler instances work as a unit to achieve the abstraction layer for the storage engine architecture. Figure 7-1 depicts these classes and how they are derived to form a new storage engine. The drawing shows the handlerton structure as an interface between the handler and the new storage engine.

But there are more preferences you can manage; you ll need to add them manually from the list in Table 11-1.

An object that can be directly retrieved or updated via the data portal An object that contains other business objects as part of its state An object that is contained by another business object

Figure 7-1. Pluggable storage engine class derivation A complete detailed investigation of the handler class is beyond the scope of this book. Instead, I ll demonstrate the most important and most frequently used methods of the handler class implementing the stages of the sample storage engine. I ll explain each of the methods implemented and called in a more narrative format later in this chapter. As a means of introduction to the handler class, I ve provided an excerpt of the handler class definition in Listing 7-2. Take a few moments now to skim through the class. Notice the many methods available for a wide variety of tasks, such as creating, deleting, altering tables and methods to manipulate fields and indexes. There are even methods for crash protection, recovery, and backup. Although the handler class is quite impressive and covers every possible situation for a storage engine, most storage engines do not use the complete list of methods. If you want to implement a storage engine with some of the advanced features provided, you should spend some time exploring the excellent coverage of the handler class in the MySQL reference manual. Once you become accustomed to creating storage engines, you can use the reference manual to take your storage engine to the next level of sophistication. Listing 7-2.

A root object may be a stand-alone object. It may also be a parent if it contains child objects. A child object could also be a parent if it, in turn, contains other child objects. An example of a root and parent object is an Invoice, while an example of a child object would be a LineItem object within that Invoice. Child objects are related to root objects via a containment relationship, as illustrated by the class diagram in Figure 3-3.

The business programmer makes the choice about whether an object is a child or not through code. By default, an object is a root object, and is only considered to be a child object if the MarkAsChild() method is called in the object s constructor. The MarkAsChild() method looks like this: protected void MarkAsChild() { _isChild = true; }
