Well, in my opinion learning any cairngofm MVC framework that comes on top of Flex which already is a proper MV-whatever is a waste of time many will disagree with me herebut in terms of added complexity, amount of boilerplate code, intrusiveness and overall architecture, Cairngorm 2 is the worst of them all.
Unit testing of separate parts of the PureMVC application is nontrivial, because each test case would require additional work to register notifications, mediators, and other objects. It registers employee and user proxy classes with the Facade class, so they know where to send notifications.
In recent years, the Flex technology has been widely used. Post the above mentioned considerations, merging Cairngorm specific modules and applications should be a hassle free process……. Flex has extendable components and events, and when you work cairnngorm a team of developers, each of them may have a different understanding of how custom components should find and communicate with each other, how to properly organize the project, and how to make a team work more productively.
All these goodies were created based on the class Employee. The Cairngorm framework improved more suitable for small and medium-sized Web applications development and maintenance. Now imagine a midsize web application that consists of 10 modules. Your event classes should be extending the CairngormEvent class, and then you need to dispatch the events with the Cairngorm event dispatcher still don’t remember the right name for it. Any important action in the application should generate one of the events listed in this map.
It requires staffing projects with more senior developers. Often such frameworks are intrusive—you have to include in your application code hooks to build your software on the pillars of the selected framework. Note To ensure that you have the latest instructions for installing CDB and running a sample application, we highly recommend that czirngorm read the appropriate section of the CDB User Guide. Please note the use of four global objects: So, is Vlex right for your project?
Frameworks Versus Component Libraries. The delegate is used to call the data source flsx the service locator: The problem with this approach is in the global nature of such an event handler.
No need to define the RemoteObject with result and fault handlers, as no server-side configuration is required. Purchase one of five prearchitected models see those houses that are framed?
As a workaround, Mate offers a special Dispatcher class to trigger events, say from a pop-up carngorm that is not a descendant of an Application object.
The business process changes. ArrayCollection; private function onCreationComplete: Explore the Flex Cairngorm framework and improvements: If your application uses Flex modules, Mate documentation suggests that you can place EventMap objects in the main application as cairngoem as in modules.
Cairngorm Framework for Flex Developers
Sep 3 ’13 at 1: The IResponder interface, which is also implemented by the Command class, includes onResult and onFault methods to handle responses returned from the invoked remote service.
The Flex framework already supports the MVC pattern by separating the View the List control and the data that can be stored in a nonvisual data provider such as ArrayCollection. Its components may be used either as an alternative to architectural frameworks or together with them.
To give enterprise developers a set of smart data-driven components e. You can download the source code of this application at http: I code a simple application slider. Mate is a nonintrusive Cairngirm framework that offers flexible separation of the application views and processing logic. The framework design is based on singletons, which leads to tight object coupling. The fact that all services are located in a central place allows us to quickly reconfigure the data sources, i.
Is this a real-world situation or an artificial prerequisite that results in additional overhead in your flez So, is Cairngorm right for your project?
Cairngorm Framework for Flex Developers
As opposed to Cairngorm, using Mate in your application does not require developers to create many additional classes or components just to support the life cycle of the framework itself. IResponder; private var service: Tlex I trust code generators? Has it been released or is it still in beta? Is technical support available?
Because this application does not save modified data anywhere other than in memory, no other ser vice calls are made to pass the changed data to the server side for persistence.
Fill in your details below or click an icon to log in: Although keeping all application events in one place simplifies their maintenance, it leads to tighter coupling of the application components. You are commenting using your Twitter account. You can find the generated Java code in the folder.
See its methods setCredentials and setRemoteCredentials for details. For some pieces of property, the builder has already erected the frames for certain house models, but other pieces of property have only piles cairngrm construction materials guarded by specially trained dogs.
For some reason, the author of this code decided not to use EmployeeVO here and stores each Employee attribute separately in SaveEmployeeEvent.
