Swiz Framework (quick tour)

Swiz is a framework for Flex, AIR and Flash that was created for the rapid development of RIA applications. The main features of swiz are:

• Control Inversion (IoC) / Dependency Injection
• Event management and mediators
• Simple life cycle for remote calls
• A framework that does not depend on your code.

Compared to other frameworks for Flex:

• No need for JEE patterns
• No need for a bunch of duplicate folders
• No heaps of copied pieces of code
• It is not necessary to inherit the framework classes.

The two basic principles of the framework describe these two diagrams:

Dependency injection

1. The controller using meta tags indicates the dependence on any service
   [Inject]
public var userDelegate:IUserDelegate;
   
2. Swiz finds the corresponding implementation of this interface.
3. Swiz inject required service to controller

Event mediation

1. The controller using meta tags indicates interest in any event.
   [Mediate(event="LoginEvent.LOGIN", properties="user")]
public function login(user:User):void
   
2. UI Displays a regular event with bubbling enabled
   (Best Practices imply the use of the Presentation Model which will dispatch events)
3. Swiz automatic executes commands in the controller that are interested in events.

Basic documentation is available on the developer’s website.
