Examples of java.util.prefs.Preferences.sync()

java.util.prefs.Preferences.sync()
Ensures that future reads from this preference node and its descendants reflect any changes that were committed to the persistent store (from any VM) prior to the sync invocation. As a side-effect, forces any changes in the contents of this preference node and its descendants to the persistent store, as if the flush method had been invoked on this node. @throws BackingStoreException if this operation cannot be completeddue to a failure in the backing store, or inability to communicate with it. @throws IllegalStateException if this node (or an ancestor) has beenremoved with the {@link #removeNode()} method. @see #flush()
