类名称：XMLChoiceCollectionMapping

XMLChoiceCollectionMapping介绍

[英]PUBLIC:

Purpose:Provide a mapping that can map a single attribute to a number of different elements in an XML Document. This will be used to map to Choices or Substitution Groups in an XML Schema

Responsibilities:

• Allow the user to specify XPath -> Type mappings
• Handle reading and writing of XML Documents containing a collection of choice or substitution group elements

The XMLChoiceCollectionMapping is the collection version of the XMLChoiceMapping. This mapping allows the user to specify a number of different xpaths, and types associated with those xpaths. When any of these elements are encountered in the XML Document, they are read in as the correct type and added to the collection.

Setting up XPath mappings:Unlike other OXM Mappings, instead of setting a single xpath, the addChoiceElement method is used to specify an xpath and the type associated with this xpath.
xmlChoiceCollectionMapping.addChoiceElement("mystring/text()", String.class);
xmlChoiceCollectionMapping.addChoiceElement("myaddress", Address.class);
[中]公众：
目的：提供一种映射，可以将单个属性映射到XML文档中的多个不同元素。这将用于映射到XML模式中的选项或替换组
责任：
*允许用户指定XPath->Type映射
*处理包含选择或替换组元素集合的XML文档的读写
XMLChoiceCollectionMapping是XMLChoiceMapping的集合版本。此映射允许用户指定许多不同的XPath，以及与这些XPath关联的类型。在XML文档中遇到这些元素时，它们将作为正确的类型读入并添加到集合中。
设置XPath映射：与其他OXM映射不同，addChoiceElement方法用于指定XPath以及与此XPath关联的类型，而不是设置单个XPath。
xmlChoiceCollectionMapping。addChoiceElement（“mystring/text（）”，字符串。阶级）；
xmlChoiceCollectionMapping。addChoiceElement（“myaddress”，Address.class）；
