Preferences' systemRoot and userRoot are stored in HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Prefs and HKEY_CURRENT_USER\Software\JavaSoft\Prefs correspondingly. author:    Konstantin Kladko version:    1.24, 05/05/07 See Also:   Preferences See Also:   PreferencesFactory since:    1.4 Field Summary final static  Preferences systemRoot      System root node. final static  Preferences userRoot      User root node.

Field Detail systemRoot final static Preferences systemRoot(Code) System root node. userRoot final static Preferences userRoot(Code) User root node. Method Detail childSpi protected AbstractPreferences childSpi(String name)(Code) Implements AbstractPreferences childSpi() method. Constructs a child node with a given name and creates its underlying Windows registry node, if it does not exist. Logs a warning message, if Windows Registry is unavailable. childrenNamesSpi protected String[] childrenNamesSpi() throws BackingStoreException(Code) Implements AbstractPreferences childrenNamesSpi() method. Calls Windows registry to retrive children of this node. Throws a BackingStoreException and logs a warning message, if Windows registry is not available. flush public void flush() throws BackingStoreException(Code) Implements Preferences flush() method. Flushes Windows registry changes to disk. Throws a BackingStoreException and logs a warning message if Windows registry is not available. flushSpi protected void flushSpi() throws BackingStoreException(Code) Empty, never used implementation of AbstractPreferences.flushSpi(). getSpi protected String getSpi(String javaName)(Code) Implements AbstractPreferences getSpi() method. Gets a string value from the underlying Windows registry node. Logs a warning, if Windows registry is unavailable. See Also:   WindowsPreferences.putSpi(String,String) keysSpi protected String[] keysSpi() throws BackingStoreException(Code) Implements AbstractPreferences keysSpi() method. Gets value names from the underlying Windows registry node. Throws a BackingStoreException and logs a warning, if Windows registry is unavailable. putSpi protected void putSpi(String javaName, String value)(Code) Implements AbstractPreferences putSpi() method. Puts name-value pair into the underlying Windows registry node. Logs a warning, if Windows registry is unavailable. See Also:   WindowsPreferences.getSpi(String) removeNodeSpi public void removeNodeSpi() throws BackingStoreException(Code) Implements AbstractPreferences removeNodeSpi() method. Deletes underlying Windows registry node. Throws a BackingStoreException and logs a warning, if Windows registry is not available. removeSpi protected void removeSpi(String key)(Code) Implements AbstractPreferences removeSpi() method. Deletes a string name-value pair from the underlying Windows registry node, if this value still exists. Logs a warning, if Windows registry is unavailable or key has already been deleted. sync public void sync() throws BackingStoreException(Code) Implements Preferences sync() method. Flushes Windows registry changes to disk. Equivalent to flush(). See Also:    flush() syncSpi protected void syncSpi() throws BackingStoreException(Code) Empty, never used implementation of AbstractPreferences.flushSpi().
