Cairngorm is based on Model View Controller (MVC) framework, specifically designed to facilitate complex state and data synchronization. Over the past few years, Cairngorm architecture has been hugely embraced for developing enterprise Flex applications. While there are a lot of. For the love of GOD, don’t use Cairngorm (2) as a framework. Use either RobotLegs or Parsley. Both of which has awesome documentation.

Your goal remains the same: Value objects must implement the Cairngorm ValueObject interface. EmployeeDTO; Bindable] public var collection: Now archotecture the Ant script daoflex-build. Post the above mentioned considerations, merging Architecure specific modules and applications should be a hassle free process……. Adobe Flash Media Server. Its components may be used either as an alternative to architectural frameworks or together with them.

We recommend you to take a close look at Swiz and Parsley, which are light MVC frameworks that implement the Inversion of Control design pattern. The Controller is the most sophisticated part of the Cairngorm architecture. In Cairngorm everything should be mapped to an event. Cairngorm follows the principle of separating the view and business logic which is known as the Model-View-Controller pattern MVC.

Now imagine a midsize web application that consists of 10 modules. A static reference arhitecture the ModelLocator singleton instance is used by the View layers to locate the required data. This site uses cookies.

Flex architecture

Somehow almost all the service return information should have an object in the Model locator. After the controller tier that routes commands come the proxy classes that deal with both—data models and the service calls if need be.

Each of these frameworks has the same goal: The other benefit is reusability of the modules. Do I trust code generators?


You can download Eclipse JEE at http: Developers have to write lots of additional classes, which adds to the project timeline. Brief description of Flex Modules: Start Free Trial No credit card required.

Mate is the youngest of all frameworks reviewed in this chapter. Using a centralized ModelLocator also makes multiple components dependent on the knowledge of the properties of the model. There are tons of articles and diagram to discuss about. In Mate, as opposed to Cairngorm, an application developer can configure multiple handlers for each event and specify the sequence in which they should be invoked by assigning priorities in the event handler.

The benefits are obvious: The delegate is created within a command object. The View portion of the employee list gets updated automatically as a result of data binding.

Mate also uses singletons, but they do not have to be instantiated by application developers. Posted by Rajesh Yadav at 1: If you have to develop a project without experienced Flex developers on your team, however, Cairngorm can give your project a structure that will prevent it from failing.

You can download the source code of this application at http: Contains UI controls for user interaction and displays the state of the models data. It allows only one-to-one mapping between events and commands.

Adobe Flex provides you with an extendable framework that you can use as a solid starting point for your business application. Please note that the code for the six participants mentioned earlier is organized in separate packages folders.

Flex MVC Architecture (CAIRNGORM)

From the learning curve perspective, none of the reviewed frameworks is overly difficult to master. The above solution should cater to those still using Cairngorm 2 and facing problems with singletons ….

All these singletons, managers, and event maps are a way to establish communication between the cairnggorm parts. For example, you have to create additional event and command classes for every event that can be dispatched in your application. On the same note, changes in the UI are propagated to the server side through this business layer. It does not support automatic data synchronization between the client and the server LCDS Data Management Service and would require manual programming in this area.


It cairngrom developers to write lots of additional classes, which adds to project timeline. It does not have to load all modules when it starts, nor does it have to load any modules if the user does not interact with them. A 6-part series by Adobe Professional Services cairnogrm explains the why and how to build an application with Cairngorm.

The title of this section is a bit of a misnomer, because Flex itself is a framework. Your team is working on a flex project that is part of the bigger picture a baseline Flex Application. The method execute must have an argument—the instance of the CairngormEvent object that may or may not encapsulate some application data for example, some value object that is not used in our scenario.

Create a common ancestor to all your commands and define the fault method there to avoid repeating the same code in each command class. View Because each model located inside the ModelLocator is bound to a UI control, its content gets updated automatically. It was developed by iteration:: You are commenting using your Facebook account.

If one of them will get updated, not only will its listener get notified ni update the view, but the other 9 will get this event, too. Cairngorm has been around longer than any other Flex framework.
