Shagami FrontController allows you to map only one command per event, yet your application may need to have several event listeners per command. 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. Cairngorm was designed to ensure that UI components do not need to know where data is located. Model Locator carries all the transport information between the components It is a Bindable object. Another line of business has to be handled by your application. You are commenting using your Facebook account.

Cairngorm[ edit ] Cairngorm is one of the primary open-source software frameworks for application architecture in Adobe Flex. It was developed by iteration::two, which was acquired by Macromedia in It is part of the Adobe Engagement Platform. Adobe Labs features Cairngorm as the architectural framework for Rich Internet Application programmers. Cairngorm is based on the MVC model. 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.
The role of the View layer in a Cairngorm application is to throw events and bind to data stored in the Model. Components on the View can bind to Value Objects or other properties in the Model data layer. In a Cairngorm Model, related data are stored in Value Objects VOs , while simple variables can be stored as direct properties of the ModelLocator class.
A static reference to the ModelLocator singleton instance is used by the View layers to locate the required data. The Controller is the most sophisticated part of the Cairngorm architecture.
The Controller layer is implemented as a singleton FrontController. The event object may include additional data if required by the developer. The execute method can update the central Model, as well as invoke a Service class which typically involves communication with a remote server.
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.
