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

java.util.prefs.Preferences.removeNode()
Removes this preference node and all of its descendants, invalidating any preferences contained in the removed nodes. Once a node has been removed, attempting any method other than {@link #name()}, {@link #absolutePath()}, {@link #isUserNode()}, {@link #flush()} or{@link #node(String) nodeExists("")} on the correspondingPreferences instance will fail with an IllegalStateException. (The methods defined on {@link Object}can still be invoked on a node after it has been removed; they will not throw IllegalStateException.)
The removal is not guaranteed to be persistent until the flush method is called on this node (or an ancestor).
If this implementation supports stored defaults, removing a node exposes any stored defaults at or below this node. Thus, a subsequent call to nodeExists on this node's path name may return true, and a subsequent call to node on this path name may return a (different) Preferences instance representing a non-empty collection of preferences and/or children. @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 alreadybeen removed with the {@link #removeNode()} method. @throws UnsupportedOperationException if this method is invoked on the root node. @see #flush()
