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

 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 – 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

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.
