The Advent of Cairngorm
Cairngorm started life in the year 2002 in the form of an ActionScript library meant for building applications which relate a form of the MVC (Model-View-Controller) pattern. It went on for some time until the project turned open-source in the year 2004. During this time, numerous third-party frameworks too were developed plus released and so, a trend did emerge towards IoC (Inversion-of-Control) frameworks.
However, in the year 2009, Cairngorm’s scope increased, thus, changing the framework of MVC into a wider foundation of tools, guidelines, and libraries which apply all across several frameworks. For a person to get started with Cairngorm, he must start on the page of Cairngorm Guidelines where he will come across a few introductory materials plus a sample application. Hence, it doesn’t come as a surprise that whenever students buy assignment help online on Cairngorm from us, they get flying colors in their assignment papers.
What is the Cairngorm Architectural Framework?
Cairngorm follows the belief of segregating the business and view logic which is recognized as the MVC (Model-View-Controller) pattern. The following list displays the various components which form the framework:
- View – It comprises UI controls and displays the models’ data state.
- Model Locator – This does its job in the form of a centralized repository for data which is required in the application.
- Value Object – VO is a class which possesses properties for storing values. It comprises no logic or method and works as a data container only.
- Event – Everything must be mapped to events in Cairngorm. At times, when a user has an interaction with the view or when an action happens, then an event should be dispatched.
- Command – Commonly, commands do a major part of application work. It is the job of the commands to receive an event and implement the logic an.
- Front Controller – Front Controller stretches the FrontController class of Cairngorm and maps the posted events to the corresponding commands.
- Service Locator – It is implemented in the form of a singleton and it comprises references to every service that an application will utilize.
- Business Delegates – They form a layer of abstraction between the chief fronted application and server-side services.
- Responder – A responder does receive a service call’s results and implement fronted-logic similar to a command.
