类名称：XPathNode

XPathNode介绍

[英]INTERNAL:

Purpose: XPathNodes are used together to build a tree. The tree is built from all of the XPath statements specified in the mapping metadata (mappings and policies). This tree is then navigated by an EventObjectBuilder to perform marshal and unmarshal operations.

The XPaths "a/b" and "a/c" would result in a tree with the root "a" and two child nodes "b" and "c".

Responsibilities:

• All tree relationships must be bi-directional.
• Reference a NodeValue, XPathNodes without a Node value represent grouping elements.
• Reference an XPathFragment, XPathFragments contain name and namespace information.
• Must differentiate between child nodes that correspond to elements and those that do not.
• Must represent special mapping situations like any and self mappings.
  [中]内部：
  用途：XPathNodes一起用于构建树。树是根据映射元数据（映射和策略）中指定的所有XPath语句构建的。然后，EventObjectBuilder将导航此树，以执行封送和解封操作。
  XPath“a/b”和“a/c”将生成一个根为“a”的树以及两个子节点“b”和“c”。
  责任：
  *所有树关系都必须是双向的。
  *引用NodeValue时，没有节点值的XPathNodes表示分组元素。
  *引用XPathFragment时，XPathFragments包含名称和命名空间信息。
  *必须区分对应于元素的子节点和不对应于元素的子节点。
  *必须表示特殊的映射情况，如任何映射和自映射。
