3 Q: Tom can you reflect a bit on the Eclipse 4?

4 The compat layer

5 The combat layer

6 e4 spec ed world The Brain Application Model Nervous system (OSGi) Service Components & DI-Container Sense organ UI (SWT/FX/ )

7 combat world The (split) Brain Application Model $n - Registries Nervous system DI & Service Compat- Layer Sense organ UI (SWT/ FX/ ) Legacy

8 Q:Tom what s your take on e4 core and DI components?

9 How OSGi spec ed the world Service-Impl 1 (requires Equinox, ) Service-Impl $N (requires Felix, ) Service-API (requires NOTHING) Consumer (requires Service-API)

10 How e4 core implemented it Service-Impl 1 Service-API (requires Equinox) Consumer (requires Service-API & transitive Equinox)

14 Q: Tom what s your take on OSGi in e4 APIs?

27 Q: What API does e4 use from OSGi?

28 e4 OSGi API useage

29 e4 OSGi API useage Pattern 1 - Debug/Log import org.eclipse.osgi.framework.log.frameworklog; import org.eclipse.osgi.framework.log.frameworklogentry; FrameworkLog log = FrameworkLogEntry logentry = new FrameworkLogEntry("org.eclipse.core.e4.di", FrameworkLogEntry.ERROR, 0, "I m an error", 0, e, null);

30 e4 OSGi API useage Pattern 1 - Debug/Log import org.eclipse.osgi.framework.log.frameworklog; import org.eclipse.osgi.framework.log.frameworklogentry; FrameworkLog log = FrameworkLogEntry logentry = new FrameworkLogEntry("org.eclipse.core.e4.di", FrameworkLogEntry.ERROR, 0, "I m an error", 0, e, null); Pattern 2 - Accessing OSGi-Service BundleContext bundlecontext = FrameworkUtil.getBundle(BlaBla.class).getBundleContext(); ServiceReference<ComponentA> servicereference = bundlecontext.getservicereference(greetservice.class); if( servicereference!= null ) { bundlecontext.getservice(servicereference).greet("hello Tom");

31 Q: Ok. Got you. But can anything be done against that
