本文整理了Java中org.eclipse.persistence.internal.oxm.XPathFragment类的一些代码示例，展示了XPathFragment类的具体用法。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。XPathFragment类的具体详情如下：
包路径：org.eclipse.persistence.internal.oxm.XPathFragment
类名称：XPathFragment

XPathFragment介绍

[英]INTERNAL:

Purpose: Represents a token from an XPath statement.

For example the following XPath statment a/b[2]/text() corresponds to three XPathFragments: "a", "b[2]", and "text()".

Responsibilities:

• Maintain name, namespace, and prefix information.
• Maintain information about the corresponding node type.
• Maintain index information if any. The XPathFragment corresponding to b[2] would have an index value of 2.
  [中]内部：
  用途：表示XPath语句中的标记。
  例如，下面的XPath语句a/b[2]/text（）对应于三个XPathFragments：“a”、“b[2]”和“text（）。
  责任：
  *维护名称、命名空间和前缀信息。
  *维护有关相应节点类型的信息。
  *维护索引信息（如有）。对应于b[2]的XPathFragment的索引值为2。
