Activator (OpenNMS 2022.1.1 API)

java.lang.Object
- org.opennms.osgi.internal.Activator

All Implemented Interfaces:

EventListener, org.osgi.framework.BundleActivator, org.osgi.framework.BundleListener, org.osgi.framework.SynchronousBundleListener
```
public class Activator
extends Object
implements org.osgi.framework.BundleActivator, org.osgi.framework.SynchronousBundleListener
```
Each opennms-bundle which uses vaadin wants to listen to Session-Events (such as sessionInitialized and sessionDestroyed), In addition we need a OnmsServiceManager service. This bundle registers a EventRegistry and a OnmsServiceManager to the OSGI-Container at bundle activation when the property "OnmsAutoExportServices" is set in the MANIFEST.MF file.
