Package org.osgi.service.prefs
Interface PreferencesService
public interface PreferencesService
The Preferences Service.
Each bundle using this service has its own set of preference trees: one for system preferences, and one for each user.
A PreferencesService
object is specific to the bundle which
obtained it from the service registry. If a bundle wishes to allow another
bundle to access its preferences, it should pass its
PreferencesService
object to that bundle.
