本文整理了Java中org.apache.openjpa.persistence.XMLPersistenceMetaDataSerializer类的一些代码示例，展示了XMLPersistenceMetaDataSerializer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。XMLPersistenceMetaDataSerializer类的具体详情如下：
包路径：org.apache.openjpa.persistence.XMLPersistenceMetaDataSerializer
类名称：XMLPersistenceMetaDataSerializer

XMLPersistenceMetaDataSerializer介绍

[英]Serializes persistence metadata back to XML. This class processes all object level tags that are store-agnostic. However, it provides hooks for the subclasses to include store-specific tags to be serialized both at <entity-mappings> and <entity> level.
[中]将持久性元数据序列化回XML。此类处理所有与存储无关的对象级标记。然而，它为子类提供了钩子，使其包含要在<entity mappings>和<entity>级别序列化的存储特定标记。

@Override
