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.
