2 OA Code Generation
OABuilder uses OACodeGen to generate full-stack code — including the object graph, UI templates, REST APIs, database access, and real-time sync.

Create model
3 Object Graph is now created
Once generated, the model becomes a live, reactive object graph — powering your app's logic, UI, sync, and data access in real time.
// select all of the Open Orders HubhubOrder = new Hub(): hubOrder.select(OrderPP.isOpen()); // create a Master-Detail Hub hubOrderItem = hubOrder.getDetailHub(Order.P_OrderItems); for (Order order : hubOrder) { // .. do something } // create filtered Hub for open Orders from Customers with large balances Hub hubOrderOverDue = new Hub(Order.class): HubFilter hf = new HubFilter(hubOrder, hubOrderOverDue); hf.addGreater(OrderPP.customer().currentBalance(), 5000); // hubOrderOverDue is now populated hubOrderOverDue.onAdd(onEvent -> { // custom code }); // sample order = hubOrder.findFirst(); hubOrder.setActiveObject(order); // this will auto populate hubOrderItem 4 Improve & Extend custom Libraries that work with OAObjectGraph
OA’s modular libraries can be extended or replaced. Build your own reusable components to match your architecture or business needs.
5 Customize in your IDE
Use your existing tools — IntelliJ, Eclipse, Maven, Git — to customize, test, and deploy as usual.

6 Run Full-Stack-App
Regenerate your app from the model anytime. OA ensures your code stays synchronized and fully runnable.
