Class RequiredConfigurationPluginTracker

java.lang.Object

org.apache.felix.cm.impl.RequiredConfigurationPluginTracker

All Implemented Interfaces:

org.osgi.util.tracker.ServiceTrackerCustomizer<org.osgi.service.cm.ConfigurationPlugin,org.osgi.service.cm.ConfigurationPlugin>

public class RequiredConfigurationPluginTracker
extends Object
implements org.osgi.util.tracker.ServiceTrackerCustomizer<org.osgi.service.cm.ConfigurationPlugin,org.osgi.service.cm.ConfigurationPlugin>

This tracker tracks existence of configuration plugins which have a PROPERTY_NAME property. The tracker checks just for existence of a plugin and tries to get it. However, this is not a guarantee that the plugin can and actually is used by the configuration admin as the admin has a separate tracker.
