Cairngorm is a lightweight micro-architecture framework for Rich Internet Applications built in Flex or AIR, defining best-practices for a RIA. Instead of adding/mapping commands in AppController ‘s constructor. Declare it in initialize() function. Example is given below for your reference. public class. Cairngorm is based on Model View Controller (MVC) framework, specifically designed to facilitate complex state and data synchronization.

It’s been more than 5 years since I last used Cairngorm this is Cairngorm 2 right? I tlex posted a post with an example. To make some of the columns editable, change the editable attribute of these DataGridColumn s to true. But it is complicate and hard to csirngorm and maintain. Modularizing Flex applications is one of the major ways of minimizing the size of the downloadable Shockwave Flash SWF files.

If you are a development manager starting a Flex project with a team that has at least one senior Flex architect, using Clear Toolkit is the productive way to go.

It analyzes general system architecture and application developing frameworks and puts them into practice. For example, employee startDate will be stored as a string and will require code to convert it to Date if any date manipulations will be needed. It allows separate responsibilities of developers.

cairnngorm It also implements the interface IResponderwhich requires you to add the result and fault methods. Is it well documented? Sign up using Email and Password. Do I need to modularize the application to be developed? Because each model located lfex the ModelLocator caorngorm bound to a UI control, its content gets updated automatically.

In such scenarios, if the module does not have much dependency on the parent application then the module-application integration is many a times postponed till cairnform module starts bearing the fruits, thereby delaying the bitter task of merging architectures This should generally be a task that should be initiated as soon as you analyze the module design. Case C gives you complete freedom of choice, as long as you have all the components and the know-how to put them together.

Mate does not force you to extend any classes. The command folder is for Command classes; control is for events and FrontController ; the ModelLocator is located in the model folder; and the view folder has visual components as shown in Figures through The global ModelLocator object defines multiple bindable variables representing different models, and the Flex compiler may generate additional EventDispatcher objects on the class level this depends on the types of the variables.

The execute method can update the central Model, as well as invoke a Service class which typically involves communication with a remote server. It is specifically designed to facilitate complex state and data synchronization between the client and the server, while keeping the programming of the View layer detached from the data implementation.

Czirngorm merging Flex Modules and Application that are independently designed using Cairngorm Architecture, following classes should be paid attention to and handled as follows: The delegate is used to call the data source through the service locator: Clear Toolkit is not an architectural framework; it is a set of open source Flex components and utilities that may be called an application framework.

Application components are also instantiated by the framework as per MXML tags included in the EventMap object, which also performs the role of a class factory with lazy instantiation—if the event that required an instance of EmployeeManager was never triggered, the instance is not created.

The event object may include additional data if required by the developer. The Clex Controller object serves as a central registry of all Cairngorm events.

Cairngorm Framework for Flex Developers

Any important action in the application should generate one of the events listed in this map. To eliminate the need to import CairngormEventDispatcher in every view, starting from Cairngorm 2.

Hmm, not sure about the version of the framework. After this build, the Java DTO and data access classes are generated and deployed in our Tomcat servlet container.

Cairngorm separates business- and UI-related work into different layers, which means that the work of the project team can be split between developers responsible for the visual portion and those who are coding just the business logic of the application.

Kindly post your sample for Cairngorm 3. Because this application does not save modified data anywhere other than in memory, no other service calls are made to pass the changed data to the server side for persistence. Modularizing Flex applications is one of the major ways of minimizing the size of the downloadable Shockwave Flash SWF files. Explore the Flex Cairngorm framework and improvements: The Command class just needs to be modified a bit to read these parameters. Read Chapters 2and 6and then decide whether you prefer working with the components described cairngogm or one of the architectural MVC frameworks.

Just simply renaming this variable in the ModelLocator will require changes in one or more views that are bound to it. If your project cakrngorm start growing, the ModelLocator may not scale well. The Command class then processes the event by running the Command class’ execute method, which is an ICommand interface method.

It allows only one-to-one mapping between events and commands. Mate also uses singletons, but they do not have to be instantiated by application cairngkrm. Do I trust code generators?
