Structuring your flex application with swiz
2 likes754 views
The document discusses the Swiz framework for structuring Flex applications. It covers presentation patterns like MVC, dependency injection using Swiz, event mediation, services, mocks and metadata processors. Swiz enables microarchitecture and dependency injection to remove concrete dependencies and make applications extensible. It provides utilities like service helpers, global error handling and tools for event handling and metadata processing.

- 6. Model View PresenterUses contract to read/write view dataViewPresenterRead/writemodelModel
- 8. Model View ControllerResponds to user eventsViewControllerUpdatesmodelModelNotifies view
- 12. [Bindable] : dispatcheseventon state changesessionuserpersonListtaskListselectedPerson
- 13. View: Presentation and InteractionViewModelReferencespersonlisttaskdetailsNotifiesPresents model to the user
- 14. Responds to model changes, ({} databinding)
- 15. Responds to user actions, (Declarativeeventhandling)
- 17. Invokes services

- 24. MircoArchitectureFramework“Enables, but not restricts, in the implementation of an application following any given architecture”
- 25. Swiz in a nutshellDependency InjectionEvent MediationUtilitiesServiceHelperGlobal exception handlerAnd more…MetaData processors
- 26. DependencyInjection 1How can a given object obtain a reference to another object?
- 27. DependencyInjection 2Object AObject BDepends on
- 28. DependencyInjection 3Object ADI frameworkObject BObject AObject BApplicationContext
- 29. Dependencyinjection 4[Inject]public var userController:UserController;<?xml version="1.0" encoding="utf-8"?><swiz:BeanProvider <controller:UserController/></swiz:BeanProvider>
- 30. Dependencyinjection 5Typically inject by typeSpecify Bean ID if necessaryWorks with interfaces and inheritance
- 31. WhyDependencyInjection?Removes dependencies on concrete implementationsNo ServiceLocatorEasy to see dependencies
- 32. EventMediationdispatcher.dispatchEvent(new TaskEvent(TaskEvent.SAVE_TASK_SUCCESS, true));[Mediate(event="TaskEvent.SAVE_TASK_SUCCESS")]publicfunction saveTaskSuccess():void { this.closeTaskDetailsWindow(); taskController.retrieveTasks();}
- 33. EventMediation[Mediate(event="UserWindow.SAVE_CLICKED", properties="user")]public function saveUser(user:User):void { userController.addUser(user);}
- 34. ServiceHelperserviceHelper.executeServiceCall(taskService.addTask(task), onAddTaskResult, [task]);<swiz:SwizConfigid="mySwizConfig"eventPackages="nl.qnh.addressbook.event"viewPackages="nl.qnh.addressbook.view"defaultFaultHandler="{genericFault}"/>
- 35. MockDelegateHelpervar result:XML = <tasks> <task> <id>1</id> <name>This is a task</name> </task> </tasks>returnnew MockDelegateHelper().createMockResult(result);
- 36. MetaData ProcessorsEasily create your own metadata tags[Log]publicvar log:ILogger;/** Code Omitted **/log.error(“An error occured”);[MediateView(“PersonView”)]public var personView:PersonView;
- 37. MetaData ProcessorsExtend BaseMetadataProcessorImplement setUpMetadataTag and tearDownMetadataTagAdd “-keep-as3-metadata+=Log” to compiler arguments
