Class LogEventAdapter

java.lang.Object

org.apache.felix.eventadmin.impl.adapter.AbstractAdapter

org.apache.felix.eventadmin.impl.adapter.LogEventAdapter

All Implemented Interfaces:

java.util.EventListener, org.osgi.framework.ServiceListener

public class LogEventAdapter
extends AbstractAdapter
implements org.osgi.framework.ServiceListener

This class registers itself as a listener for LogReaderService services with the framework and subsequently, a LogListener callback with any currently available LogReaderService. Any received log event is then posted via the EventAdmin as specified in 113.6.6 OSGi R4 compendium. Note that this class does not create a hard dependency on the org.osgi.service.log packages. The adaption only takes place if it is present or once it becomes available hence, combined with a DynamicImport-Package no hard dependency is needed.
