本文整理了Java中javax.jcr.Node.checkout()方法的一些代码示例，展示了Node.checkout()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.checkout()方法的具体详情如下：
包路径：javax.jcr.Node
类名称：Node
方法名：checkout

Node.checkout介绍

[英]Sets this versionable node to checked-out status by setting its jcr:isCheckedOut property to true. Under full versioning it also sets the jcr:predecessors property to be a reference to the current base version (the same value as held in jcr:baseVersion). These changes are made by worksapce-write and therefore do require a save.

The part of the subgraph of this node that is affected by the checked-out status of this node becomes no longer read-only.

If this node is already checked-out, this method has no effect.
[中]通过将其jcr:isCheckedOut属性设置为true，将此可版本化节点设置为签出状态。在完全版本控制下，它还将jcr:predecessors属性设置为对当前基本版本的引用（与jcr:baseVersion中的值相同）。这些更改由worksapce write进行，因此确实需要save。
此节点的子图中受此节点的签出状态影响的部分不再是只读的。
如果此节点已签出，则此方法无效。
