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

Node.getNode介绍

[英]Returns the node at relPath relative to this node.

If relPath contains a path element that refers to a node with same-name sibling nodes without explicitly including an index using the array-style notation ([x]), then the index [1] is assumed (indexing of same name siblings begins at 1, not 0, in order to preserve compatibility with XPath).

Within the scope of a single Session object, if a Node object has been acquired, any subsequent call of getNode reacquiring the same node must return a Node object reflecting the same state as the earlier Node object. Whether this object is actually the same Node instance, or simply one wrapping the same state, is up to the implementation.
[中]返回相对于此节点位于relPath的节点。
如果relPath包含一个path元素，该元素引用具有同名同级节点的节点，而没有使用数组样式表示法（[x]显式包含索引，则假定索引[1]（同名同级节点的索引从1开始，而不是从0开始，以保持与XPath的兼容性）。
在单个Session对象的范围内，如果已获取Node对象，则任何后续调用getNode重新获取同一节点时，都必须返回一个Node对象，该对象反映的状态与之前的Node对象相同。这个对象实际上是同一个Node实例，还是仅仅是一个包装相同状态的实例，取决于实现。
