PreferencesFactory
| java.util.prefs.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.
