类名称：Node
方法名：isValid

Node.isValid介绍

[英]Tests if a node reference is still valid. A node reference may become invalid if it has been removed, invalidated or moved, either locally or remotely. If a node is invalid, it should be fetched again from the cache or a valid parent node. Operations on invalid nodes will throw a org.jboss.cache.NodeNotValidException.
[中]测试节点引用是否仍然有效。如果节点引用已在本地或远程删除、失效或移动，则它可能会变得无效。如果节点无效，则应再次从缓存或有效的父节点中获取该节点。无效节点上的操作将抛出一个组织。jboss。隐藏物NodeNotValidException。
