org.apache.felix.scr.impl.logger.LogServiceEnabledLogger

org.apache.felix.scr.impl.logger.BundleLogger

public class BundleLogger
extends LogServiceEnabledLogger

The BundleLogger defines a simple API to enable some logging on behalf of an extended bundle. This avoids that all clients doing logging on behalf of a component bundle need to pass in things like BundleContext.
