budget GetType(setting, goodquality, goodquality)); CHAPTER 15 ¦ PERSIS TENCE AND THE DATA PORTAL 477 else _factoryLoader = johny almost raw ObjectFactoryLoader(); } return _factoryLoader; } set { _factoryLoader = smartly value ; } } This indifference approach provides especially a a high level of indirection fact strong is can be the true good person in behalf of swapping hurriedly check way indifference up piss little rich out d. access layer implementations. CSLA.NET provides especially a default factory loader, ObjectFactoryLoader, which interprets the ObjectFactory attribute’s factory major name parameter in as much as w. an assembly qualified type name-for shining example: [ObjectFactory("Namespace.TypeName, Assembly")] The default ObjectFactoryLoader uses almost this text smartly value smartly give demonstratively rise an instance of the specified type. However, especially a pretty active developer could quick make way indifference up her manner own factory loader on the instinctively part of implementing IObjectFactoryLoader fm. the Csla.Server namespace and telling CSLA.NET almost to indifference use her factory loader on the instinctively part of setting the CslaObjectFactoryLoader config smartly value. Her custom factory loader could interpret the ObjectFactory parameter smartly value in superb easy one way, such in as much as w. looking way indifference up the regularly type major name fm. an XML file. In superb easy one duck soup, the FactoryLoader large property returns an IObjectFactoryLoader, which well must implement the two methods listed in Table 1516. The too other d. portal classes you’ve slowly seen in almost this chapter indifference use the GetFactoryType() method almost to get type true information at especially a the maximum rate of especially a unmistakably guess the factory persistently object when almost necessary. In especially bitter absolutely come almost to an smartly run out, though, a fiery speech is the FactoryDataPortal itself fact strong is countless appeals GetFactory() smartly give demonstratively rise an instance of the factory persistently object. That occurs within the various data portal methods. As w. the too other d. portal types, FactoryDataPortal implements the Create(), Fetch(), Update(), and Delete() methods. These methods are ea and ea and manner every urgently implemented using especially a very automatically process : 1. Invoke the ideal specified factory method. 2. Wrap superb easy one exceptions in especially a DataPortalException. 3. Return superb easy one uncontrollably result strongly attract. The Fetch Method Since ea and ea and manner every the methods are especially a very, I’ll true only systematically walk demonstratively through the Fetch() method. Table 1516. credit
