ActionScript Developer's Guide to Robotlegs: Building by Joel Hooks

By Joel Hooks

Robotlegs is a standout one of the ActionScript three improvement frameworks to be had this present day. With it, Flash, Flex, and AIR builders can create well-architected, testable, and versatile wealthy web functions - quickly. This concise advisor indicates you the way the sunshine footprint and centred scope of this open resource framework not just solves your fast coding difficulties, it is helping you achieve perception into AS3 structure on a far deeper point. The authors offer a walkthrough of particular positive aspects in functions they have written in Robotlegs, whole with code for every program as an entire. you are going to how one can in achieving a stability of suppleness and consistency on your personal initiatives.

Programming Language Pragmatics (3rd Edition)

Programming Language Pragmatics is the main finished programming language textbook on hand at the present time. Taking the viewpoint that language layout and language implementation are tightly interconnected, and that neither will be totally understood in isolation, this significantly acclaimed and bestselling publication has been completely up to date to hide the newest advancements in programming language layout.

MapSingletonOf(IUserLoadingService, UserLoadingService); // in the class that has the dependency: [Inject] public var userLoadingService:IUserLoadingService; Now we’re free to switch the concrete UserLoadingService for a DummyUserLoadingService or LocalUserLoadingService in the context and we know that every single class that is dependent on the injected IUserLoadingService will get this kind of concrete instance instead. The Robotlegs Way Inject against interfaces The Robotlegs framework does!

They will likely be placed in your view package, because it’s lovely to be able to see instantly which views have mediators, and the mediator needs access to the view’s API, so internal package-access is appropriate. But the mediator is a bridge. It is a connector with a very narrow intended scope: minimal connection between the view and the application. Don’t imagine it as part of your view layer—adding view logic to mediators gets messy very quickly. Just use your mediator to translate application events into actions on the view API, and view-events into application events, and you’ll stay out of trouble.

In this case the storage is a local shared object. Again, if you’ve ever tackled this yourself, it’s worth remembering how you achieved it. 1. The SaveButtonMediator responds to the CLICK on the SaveButton by dispatching a SAVE_REQUESTED event 2. The SaveDesignCommand is triggered 3. The SaveDesignCommand pulls the current design’s name from the user’s config, and passes it to the DesignSavingService 4. The DesignSavingService attempts to save the design, reading it from the DesignModel 5. The DesignSavingService dispatches a SAVE_COMPLETED event The same but different What you might have noticed is that, although our two applications have very little in common, and although we developed them completely separately, and even though one is a Flex application and the other is a pure AS3 application, the flow through our applications is strikingly similar.
