Name
PreferencesFactory
Synopsis
The
PreferencesFactory
interface defines the factory
methods used by the static methods of the
Preferences
class to obtain the root
Preferences
nodes for user-specific and
system-wide preferences hierarchies. Application programmers never
need to use this interface.
An implementation of the preferences API for a specific back-end data
store must include an implementation of this interface that works
with that data store. Sun’s implementation of Java
includes a default filesystem-based implementation, which you can
override by specifying the name of a
PreferencesFactory
implementation as the value of
the
“java.util.prefs.PreferencesFactory”
system property.
public interface PreferencesFactory { // Public Instance Methods Preferences systemRoot( ); Preferences userRoot( ); }
