Gain hands-on adventure with PureMVC, the preferred open resource framework for constructing maintainable functions with a Model-View-Controller structure. during this concise consultant, PureMVC author Cliff corridor teaches the basics of PureMVC improvement by means of strolling you thru the development of a whole non-trivial Adobe AIR application.
Through transparent factors and diverse ActionScript code examples, you’ll study top practices for utilizing the framework’s periods on your daily paintings. detect how PureMVC helps you to specialise in the aim and scope of your software, whereas the framework looks after the plumbing in a maintainable and transportable way.
- Get an in depth review of the PureMVC method for constructing your application
- Model the area via designing the schema and developing framework-agnostic worth objects
- Implement framework-agnostic View parts that divulge an API of occasions and properties
- Use the Proxy development to maintain song of price items and conceal carrier interaction
- Facilitate two-way conversation among a View part and the remainder of the application
- Stitch the version and think about ranges including command items within the Controller
- Manage complicated View part lifestyles cycles, and the way to reuse the version tier

Learn about the basics—in this case, writing fiction—before proceeding. Fortunately, our discovery phase in the previous section has provided us with valuable clues about the domain model for StoryArchitect. Reflecting on the various forms that fiction comes packaged in, we can easily arrive at some proposed entities. No matter what the length—from a six scene fable about three pigs and a wolf to a sweeping, multi-episode saga of galactic empire and rebellion—a Story is made of Scenes. Scenes would seem to be the atomic Story unit, but remember that a Scene may have multiple Drafts, only one of which will be considered the current Draft.
I might draft some scenes I have planned in order to get a better feel for my cast and milieu, or jot down some notes about a character’s personality and motivations, which I find a challenge. I did find a helpful site describing personality types and their related “emotional centers” and “development levels” which can inform a more believable character. A bit later, I have a bunch of folders filled with all of these bits of story stuff. I can create a new draft of a scene by copying the file and tweaking it.
It would be easy to simply dictate the feature set and implementation without preamble or explanation. But the choices we make at the code level are influenced by what we know or do not know about the domain, in this case, writing fiction. In the previous section, we were provided two of the most important inputs into a new software project that a developer could know: what the user is trying to do and how they are doing it now. Unless it is to be a copy of a competitor’s application or a variation on a product class, the developer will usually be working from what the client says they want, and most companies who wisely pay to have software written for them by professionals have core competencies in areas other than software design.
