Interface PreferencesFactory
public interface PreferencesFactory
A factory object that generates Preferences objects. Providers of new Preferences implementations should provide corresponding PreferencesFactory implementations so that the new Preferences implementation can be installed in place of the platform-specific default implementation.
This class is for Preferences implementers only. Normal users of the Preferences facility should have no need to consult this documentation.
