## 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.

  Since:
    1.4
