本文整理了Java中org.nuxeo.common.xmap.XMap类的一些代码示例，展示了XMap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。XMap类的具体详情如下：
包路径：org.nuxeo.common.xmap.XMap
类名称：XMap

XMap介绍

[英]XMap maps an XML file to a java object.

The mapping is described by annotations on java objects.

The following annotations are supported:

  • XObject Mark the object as being mappable to an XML node

  • XNode Map an XML node to a field of a mappable object

  • XNodeList Map an list of XML nodes to a field of a mappable object

  • XNodeMap Map an map of XML nodes to a field of a mappable object

  • XContent Map an XML node content to a field of a mappable object

  • XParent Map a field of the current mappable object to the parent object if any exists The parent object is the mappable object containing the current object as a field
    The mapping is done in 2 steps:

  • The XML file is loaded as a DOM document

  • The DOM document is parsed and the nodes mapping is resolved
    [中]XMap将XML文件映射到java对象。
    映射由java对象上的注释描述。
    支持以下注释：
    *XObject将对象标记为可映射到XML节点
    *XNode将XML节点映射到可映射对象的字段
    *XNodeList将XML节点列表映射到可映射对象的字段
    *XNodeMap将XML节点映射到可映射对象的字段
    *XContent将XML节点内容映射到可映射对象的字段
    *XParent将当前可映射对象的字段映射到父对象（如果存在）。父对象是包含当前对象作为字段的可映射对象
    映射分两步完成：
    *XML文件作为DOM文档加载
    *解析DOM文档并解析节点映射
