java.util.prefs

public Interface PreferencesFactory

Known Direct Implementers: java.util.prefs.FileSystemPreferencesFactory
Imports: java.util.*

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.
