JavaFX Series - Separation & Life Cycle

29 Dec 2012
Posted by Steven

With the last post of this series, I started experimenting with JavaFX. Since then, I figured out how to separate the user interface (UI) framework from the business logic and how the life cycle of the objects should be like.

First impressions

As I explained before, I want to write a small simulation in which some civilization uses growing resources to expand. The whole idea is pretty scetchy right now, but there should be a bord on which the whole simulation takes place and the mentioned resources. Because resources don't grow on their own, there are resource spawners that can be set programmatically and appear on the UI. These things spawn new resources every time the user clicks on them. The new resources (yellow thingies) are spread in a random fashion around the spawners (grey buttons):

I worked with Java Swing for quite some time now. However Swing is said to be dead since a couple of years, it seems that nobody notified some companies about that. I don't feel a siginificant movement away from Swing.

After thinking and reading about some promissing candidates, I decided to bring myself up to date with JavaFX.

Recently, I began reading Clean Code by Uncle Bob (again). In chapter 11 ("Systems"), he writes about a "Global Setup Strategy" of an application. As I understood it, it is the master plan for instantiation of objects and the references between them. Following such a strategy should separate the construction of a system from its usage.
