Riena is a client/server application framework based on OSGi and Eclipse RCP. It uses a tree-based navigation model and declarative XWT views. The document discusses how Riena's navigation model and dependency injection are related to the Eclipse e4 platform, and provides demos of Riena running on e4 with its navigation model and XWT views.

Riena in Eclipse 3.x
 RCP Workbench
 RCP Views, Perspectives, SWT, JFace
 Many Singletons i.e. PlatformUI
 Behaviour and look is inherited from Eclipse IDE
 Riena overwrites it (Presentation API) at some places
 Workspace has limitation in its extensibility

Riena Navigation Model/Processor
 Tree based Model
 Building blocks are…
 extensions („assemblies“)
 nodeBuilders (java code)
 Multiple instances per building block possible (i.e. multiple
customer records)
 Navigate from any give node in the tree to any other node
using a simple id
 Pass parameter, supply feedback with changelisteners
 Generic NavigationProcessor included to manage the tree

E4 – Workbench Model
 ECORE Model (based on EMF)
 Contains a Workbench Model based on the Eclipse IDE
 „Live“ Model
 Extensible
 Derive a „Riena Navigation Model“ from the „Eclipse Workbench
Model“

e4 – dependency injection
 Riena has Dependency Injection for OSGi Services and
Equinox Extensions for more than a year
 Implemented before e4 or JSR 330 was finished
 e4 now implements the JSR 330 standard and uses dependency
injection in many places
 e4 not only injects OSGi Services but Application Services and
other objects (i.e. parent Composite)
 both implementation (NOT surprisingly ) use annotations

e4
• method injection
• filtering & conditions
• method injection
• field injection
• constructor injection
• universal usable
• standard JSR 330

Riena - XWT
 Riena separates View and Controller
 View contains the definition of Widgets, Colors, Fonts, Layout
 Controller contains data binding, event listener, view logic
 The BindingId links the widgets in the view with the Ridget that
the Controller accesses.
 Action: Remove the Java View and replace it with a XWT View.

Conclusion
 e4 has many components that are interesting for Riena
 some are more stable than others 
 The Riena implementation gets a lot easier on e4 than on 3.x
 We will soon make a Riena build available for everyone to try
out.
