Q: What API does e4 use from OSGi?

slide-28

e4 OSGi API useage

SLIDE 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);

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"); }
