/**
 * 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 {@literal ->} 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); * */ public class XMLChoiceCollectionMapping extends DatabaseMapping implements ChoiceCollectionMapping, XMLMapping { private Map fieldToClassMappings;
