NodeChangeEvent

public class NodeChangeEvent
extends EventObject

java.lang.Object
    java.util.EventObject
      java.util.prefs.NodeChangeEvent


Preferences节点发出的事件,指示该节点的子节点已被添加或删除。

请注意,虽然NodeChangeEvent从java.util.EventObject继承了Serializable接口,但它并不是可序列化的。 实施适当的序列化方法来抛出NotSerializableException。
