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

Node.getReferences介绍

[英]This method returns all REFERENCE properties that refer to this node and that are accessible through the current Session. Equivalent to Node.getReferences(null).

If this node has no referring REFERENCE properties, an empty iterator is returned. This includes the case where this node is not referenceable.
[中]此方法返回引用此节点的所有REFERENCE属性，这些属性可通过当前[$1$]访问。相当于Node.getReferences(null)。
如果此节点没有引用REFERENCE属性，则返回一个空迭代器。这包括此节点不可引用的情况。
