The Prism Library can be used in a WPF, Silverlight, or Windows Phone 7 application. There are Prism binaries for desktop, Silverlight, and Windows Phone in the Bin folder where Prism is installed. The binaries in the Desktop folder target WPF. The Prism Library targeted for desktop applications consists of four assemblies: Microsoft.Practices.Prism. This assembly contains interfaces and components to help build composite applications. These components include the EventAggregator, ModuleManager, ModuleCatalog, and Bootstrapper. Additionally, this assembly contains components that relate to the presentation layer of the desktop application. These include CompositeCommand, DelegateCommand, CompositePresentationEvent, RegionManager, and NotificationObject. Microsoft.Practices.Prism.Interactivity. This assembly contains behaviors and actions for interactions with the UI based on Microsoft Expression Blend Behaviors (available in the Blend SDK), largely in support of the MVVM pattern. This includes InteractionRequest, InteractionRequestTrigger, Confirmation, and Notification. Microsoft.Practices.Prism.UnityExtensions. This assembly provides components for using the Unity Application Block (Unity) with the Prism Library. These components include UnityBootstrapper and UnityServiceLocatorAdapter. Microsoft.Practices.Prism.MefExtensions. This assembly provides components for using Managed Extensibility Framework (MEF) with the Prism Library. These components include MefBootstrapper and MefServiceLocatorAdapter. The Prism Library targeted for Silverlight applications consists of four assemblies. The following describes additional functionality in each component specific to Silverlight: Microsoft.Practices.Prism. For Silverlight, this assembly includes classes that handle remote module loading, such as the FileDownloader and XapModuleTypeLoader. It also accounts for some behavioral differences in controls for regions with additional adapters and behaviors, such as TabControlRegionAdapter and TabControlRegionSyncBehavior. Microsoft.Practices.Prism.Interactivity. The Silverlight version contains TriggerActions to respond to InteractionRequests, such as ConfirmationChildWindow, NotificationChildWindow, and PopupChildWindowAction. Microsoft.Practices.Prism.UnityExtensions. This assembly provides components to use Unity for Silverlight with the Prism Library. These components include UnityBootstrapper and UnitServiceLocatorAdapter. Microsoft.Practices.Prism.MefExtensions. This assembly provides components to use MEF with the Prism Library. These components include MefBootstrapper and MefServiceLocatorAdapter.

As orders flow through this pipeline, entries are added to a new database table called audit. These entries can be examined to see what has happened to an order and are an excellent way to identify problems if they occur. Each entry in the orders table is also flagged with a status, identifying which point in the pipeline it has reached. To process the pipeline, you ll create classes representing each stage. These classes carry out the required processing and then modify the status of the order in the orders table to advance the order. You ll also need a coordinating class (or processor), which can be called for any order and executes the appropriate pipeline stage class. This processor is called once when the order is placed and, in normal operation, is called twice more once for stock confirmation and once for shipping confirmation. To make life easier, you ll also define a common interface supported by each pipeline stage class. This enables the order processor class to access each stage in a standard way. You ll also define several utility functions and expose several common properties in the order processor class, which will be used as necessary by the pipeline stages. For example, the ID of the order should be accessible to all pipeline stages, so to save code duplication, you ll put that information in the order processor class. Now, let s get on to the specifics. You ll build a number of files in the business folder containing all the new classes, which you ll reference from HatShop. The new files you ll create are the following: OrderProcessor: Main class for processing orders. IPipelineSection: Interface definition for pipeline sections. PsInitialNotification, PsCheckFunds, PsCheckStock, PsStockOk, PsTakePayment, PsShipGoods, PsShipOk, PsFinalNotification: Pipeline section classes. We ll create these classes in 14; here we ll use a dummy (PsDummy) class instead. The progress of an order through the pipeline as mediated by the order processor relates to the pipeline shown earlier (see Figure 13-3).

Listing 4-5. Saving an Address Address address = new Address(); ... Session session = null; Transaction tx = null; try { session = factory.openSession(); tx = session.beginTransaction(); session.persist(address); tx.commit(); } catch (Exception e) { if (tx != null) tx.rollback(); } finally { session.close(); } The code in Listing 4-5 follows the pattern you ll use when interacting with Hibernate mapped objects in a simple J2SE application. Behind the scenes the Hibernate Session just opened is given a JDBC connection for the database set in the SessionFactory configuration (this connection might be a new connection or might come from a pool of existing connections available to Hibernate). Once the Session is opened it acts as cache for mapped object entities, that is, any object you retrieve or save via the opened Session will now be in the Session cache. So, if you were to load the same object twice, in the first call Hibernate will issue a SQL statement to load the state of the object, but in any subsequent calls using the same Session, the object would be retrieved from the Session s internal cache and no database access would occur. If the code in Listing 4-5 executes successfully, the Address instance that was passed to the persist method will now have its Id field populated with the identifier generated by the database and there will be a new row in the ADDRESS table. Hibernate s Session object provides several methods that persist the state of an object to the database, including persist, save, update, and saveOrUpdate. If an object s primary key attribute isn t set, Hibernate will detect this and automatically generate a primary key for the object based on the strategy selected on the id element. This will make the underlying operation a SQL INSERT.
