本文整理了Java中javax.jcr.Node.update()方法的一些代码示例，展示了Node.update()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Node.update()方法的具体详情如下：
包路径：javax.jcr.Node
类名称：Node
方法名：update

Node.update介绍

[英]If this node does have a corresponding node in the workspace srcWorkspace, then this replaces this node and its subgraph with a clone of the corresponding node and its subgraph.

If this node does not have a corresponding node in the workspace srcWorkspace, then the update method has no effect.

If the update succeeds the changes made are persisted immediately, there is no need to call save.

Note that update does not respect the checked-in status of nodes. An update may change a node even if it is currently checked-in (This fact is only relevant in an implementation that supports versioning).
[中]如果此节点在工作区srcWorkspace中确实有一个对应的节点，则会用对应节点及其子图的克隆来替换此节点及其子图。
如果此节点在工作区srcWorkspace中没有相应的节点，则update方法无效。
如果update成功，所做的更改将立即持久化，则无需调用save。
请注意，update不尊重节点的签入状态。update可能会更改节点，即使该节点当前已签入（此事实仅与支持版本控制的实现相关）。
