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

Node.getNodes介绍

[英]Returns all child nodes of this node accessible through the current Session. Does not include properties of this Node. The same reacquisition semantics apply as with #getNode(String). If this node has no accessible child nodes, then an empty iterator is returned.
[中]返回可通过当前Session访问的此节点的所有子节点。不包括此Node的属性。与#getNode（String）相同的重新获取语义也适用。如果该节点没有可访问的子节点，则返回一个空迭代器。

propIter.nextProperty().accept(this);
NodeIterator nodeIter = node.getNodes();
while (nodeIter.hasNext()) {
  nodeIter.nextNode().accept(this);
  nextQueue.addLast(propIter.nextProperty());
NodeIterator nodeIter = node.getNodes();
while (nodeIter.hasNext()) {
  nextQueue.addLast(nodeIter.nextNode());
