All Implemented Interfaces:

EventListener, org.osgi.framework.BundleListener, org.osgi.util.tracker.ServiceTrackerCustomizer<Object,Object>

class ExtLogManager
extends ScrLogManager

Implements an extension to the SCR log manager that uses logger names to create a hierarchy of loggers. All messages will be logged via the SCR logger's bundle unlike the classic scr log manager that used the bundle's logger.

• An ScrLogger will log with the name
• A BundleLogger will log with the name + the bundle symbolic name
• A ComponentLogger will log with the name + the bundle symbolic name + "." + component name
