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

Node.getPrimaryItem介绍

[英]Returns the primary child item of this node. The primary node type of this node may specify one child item (child node or property) of this node as the primary child item. This method returns that item.

In cases where the primary child item specifies the name of a set same-name sibling child nodes, the node returned will be the one among the same-name siblings with index [1].

The same reacquisition semantics apply as with #getNode(String).
[中]返回此节点的主子项。此节点的主节点类型可以将此节点的一个子项（子节点或属性）指定为主子项。此方法返回该项。
如果主子项指定了一组同名同级子节点的名称，则返回的节点将是索引为[1]的同名同级节点中的节点。
与#getNode(String)相同的重新获取语义也适用。
