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.

Have you noticed that the Command class has also reached for the AppModelLocator to be able to update the model?

Comparing Selected Flex Frameworks. Note To ensure that you have the latest instructions for installing CDB and running a sample application, we highly recommend that you read the appropriate section of the CDB User Guide.

There are different ways of flx this goal. Software architecture Free computer libraries. When your application grows, consider creating multiple EventMap objects to keep them manageable. In technical terms, the study strives to form a development mode of mobile autonomous learning information system. Does it support modularized applications? If you are looking for an example, here it is, fleex The first cairngrm of using Cairngorm should be creating the backbone of frame work.

Installing Eclipse JEE is just a matter of unzipping the downloaded file to a folder on your hard disk. Get unlimited access to videos, live online training, learning paths, books, tutorials, and more.

The View portion contains visual components required by your application, value objects, and Cairngorm-specific event classes used for communication with the Model and Controller tiers. The value objects of the application have been placed in the folder called vo. If I make the wrong choice, how long will it take to remove this framework from the application code?


Post the above mentioned considerations, merging Cairngorm specific modules and applications should be a hassle free process……. The Command class updates the model. An fairngorm object is registered with one or more observable objects that generate notifications to be consumed by the observer. Sign up using Facebook. Application developers have to write lots of boilerplate code. By using these callbacks the delegate will return to the command cairnhorm the result or error information of the execution of the command in glex.

One of the main Flex selling points is its MXML-to-ActionScript code generator, which spares application developers from manually writing lots of xairngorm. The Controller is the most sophisticated part of the Cairngorm architecture. So far, so good.

If your application uses Flex modules, Mate documentation suggests that you can place EventMap objects in the main application as well as in modules. The FrontController instance, which receives every View-generated event, dispatches the events to the assigned Command class based on the event’s declared type.

Frameworks Versus Component Libraries. Clear Toolkit is a collection of code generators, methodologies, and smart components. If you don’t do that, your command will never get executed.

Create a user called dba with the password sql and grant this user full access to the test database. EmployeeProxy; private tlex userProxy: Suppose you have 10 [Bindable] String variables in the ModelLocator. Object-oriented programming languages arrange event-driven communication between the objects by implementing the Observer design pattern.


The application developers are not forced to do all of their plumbing exclusively via Mate and are free to use standard Flex event processing along with the EventMap object offered by Mate.

Also, make sure that the test database exists. The next point of interest is the class LoadEmployeesCommand. Sep 3 ’13 at It was open sourced in the summer of After this build, the Java DTO and data access classes are generated and deployed in our Tomcat servlet container.

The other view work flow is similar to the above… The FB Project structure like: Because this application does cairntorm 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.

While merging Flex Modules and Application that are independently designed using Cairngorm Architecture, following classes should be paid attention to and handled as follows: Just simply renaming this variable in the ModelLocator will require changes in one or more views that are bound to it.

More on me on the home page. By using these callbacks the delegate will return to the command class the result or error information of the execution of the command in question.
