Package org.apache.felix.cm.impl

Class Activator

java.lang.Object

org.apache.felix.cm.impl.Activator

All Implemented Interfaces:

org.osgi.framework.BundleActivator

public class Activator
extends Object
implements org.osgi.framework.BundleActivator

Activator for the configuration admin implementation. When the bundle is started this activator:

• Sets up the logger Log.
• A FilePersistenceManager instance is registered as a default PersistenceManager.
• Creates and sets up the ConfigurationManager.

The default FilePersistenceManager is configured with a configuration location taken from the felix.cm.dir framework property. If this property is not set the config directory in the current working directory as specified in the user.dir system property is used.
