Look at the resultset of that query, shown in figure 13.6. This resultset contains lots of redundant data. Item 1 has three bids and two images, item 2 has one bid and one image, and item 3 has no bids and no images. The size of the product depends on the size of the collections you re retrieving: 3 times 2, 1 times 1, plus 1, total 8 result rows.

Notice how we use Ant properties within this configuration file. We use the built-in ${ant.project.name} property to insert the project name into the subject of the emails sent, allowing us to easily identify which project is being reported at a quick glance. Our example build file to demonstrate the MailLogger is: code 39 c# class Code 39 C# Control - Code 39 barcode generator with free C# sample

The size of this result may well be several megabytes. Considerable processing time and memory are required on the database server to create this resultset. All the data must be transferred across the network. Hibernate immediately removes all the duplicates when it marshals the resultset into persistent objects and collections redundant information is skipped. Three queries are certainly faster! You get three queries if you map the parallel collections with fetch="subselect"; this is the recommended optimization for parallel collections. However, for every rule there is an exception. As long as the collections are small, a product may be an acceptable fetching strategy. Note that parallel single-valued associations that are eagerly fetched with outer-join SELECTs don t create a product, by nature. Finally, although Hibernate lets you create Cartesian products with fetch="join" on two (or even more) parallel collections, it throws an exception if you try to enable fetch="join" on parallel <bag> collections. The resultset of a product can t be converted into bag collections, because Hibernate can t know which rows contain duplicates that are valid (bags allow duplicates) and which aren t. If you use bag collections (they are the default @OneToMany collection in Java Persistence), don t enable a fetching strategy that results in products. Use subselects or immediate secondary-select fetching for parallel eager fetching of bag collections. c# code 39 checksum Code 39 C# SDK Library - Code 39 barcode image generator using ...

To generate Code 39 linear barcode images in Visual C# class library, you only need to add this barcode control to your project reference at first, and then copy the following C# sample code to your barcoding project for a test! All Code 39 barcode settings below are adjustable. BarCode code39 = new BarCode (); <project name="MailLogger example" default="test"> <target name="test"> <echo message="hello out there"/> </target> <target name="fail"><fail/></target> </project> Global and dynamic fetching strategies help you to solve the n+1 selects and Cartesian product problems. Hibernate offers another option to initialize a proxy or a collection that is sometimes useful. Forcing proxy and collection initialization A proxy or collection wrapper is automatically initialized whenever any of its methods are invoked (except for the identifier property getter, which may return the identifier value without fetching the underlying persistent object). Prefetching and eager join fetching are possible solutions to retrieve all the data you d need. You sometimes want to work with a network of objects in detached state. You retrieve all objects and collections that should be detached and then close the persistence context. In this scenario, it s sometimes useful to explicitly initialize an object before closing the persistence context, without resorting to a change in the global fetching strategy or a different query (which we consider the solution you should always prefer). You can use the static method Hibernate.initialize() for manual initialization of a proxy: From the command line, we specify the configuration file and invoke the fail target: Session session = sessionFactory.openSession(); Transaction tx = session.beginTransaction(); Item item = (Item) session.get(Item.class, new Long(1234)); Hibernate.initialize( item.getSeller() ); tx.commit(); session.close(); processDetached( item.getSeller() ); ... Hibernate.initialize() may be passed a collection wrapper or a proxy. Note that if you pass a collection wrapper to initialize(), it doesn t initialize the tar- > ant -f buildmail.xml -logger org.apache.tools.ant.listener.MailLogger -DMailLogger.properties.file=maillogger.properties fail Buildfile: buildmail.xml fail: BUILD FAILED C:\AntBook\Sections\Extending\listeners\buildmail.xml:7: No message Total time: 1 second get entity objects that are referenced by this collection. In the previous example, Hibernate.initalize( item.getBids() ) wouldn t load all the Bid objects inside that collection. It initializes the collection with proxies of Bid objects! Explicit initialization with this static helper method is rarely necessary; you should always prefer a dynamic fetch with HQL or Criteria. Now that you know all the options, problems, and possibilities, let s walk through a typical application optimization procedure. Because we have MailLogger.success.notify set to off, we only receive build failure emails. Setting ANT_ARGS with the appropriate -logger and -DMailLogger.properties.file settings allows us to invoke Ant simply as ant -f buildmail.xml fail.
