/**
* Any object XML mappings map an attribute that contains a single object to an XML element.
* The referenced object may be of any type (including String), and does not need not be related
* to any other particular type through inheritance or a common interface. The corresponding
* object attribute value should be generic enough for all possible application values. Note that
* each of the referenced objects (except String) must specify a default root element on their
* descriptor.
*
*
Any object XML mappings are useful with the following XML schema constructs:
* - any
* - choice
* - substitution groups
*
*
* Setting the XPath: TopLink XML mappings make use of XPath statements to find the relevant
* data in an XML document. The XPath statement is relative to the context node specified in the descriptor.
* The XPath may contain node type, path, and positional information. The XPath is specified on the
* mapping using the setXPath method. Note that for XML Any Object Mappings the XPath is
* optional.
*
*
The following XPath statements may be used to specify the location of XML data relating to an object's
* name attribute:
*
*
*
* XPath
* Description
*
*
* contact-method
* The name information is stored in the contact-method element.
*
*
* contact-method/info
* The XPath statement may be used to specify any valid path.
*
*
* contact-method[2]
* The XPath statement may contain positional information. In this case the contact
* information is stored in the second occurrence of the contact-method element.
*
*
*
* Mapping an element of type xs:anyType as an Any Object Mapping:
*
*
*
XML Schema
*
* <?xml version="1.0" encoding="UTF-8"?>
* <xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema">
* <xsd:element name="customer" type="customer-type"/>
* <xsd:complexType name="customer-type">
* <xsd:sequence>
* <xsd:element name="contact-method" type="xsd:anyType"/>
* </xsd:sequence>
* </xsd:complexType>
* <xsd:element name="address">
* <xsd:complexType>
* <xsd:sequence>
* <xsd:element name="street" type="xsd:string"/>
* <xsd:element name="city" type="xsd:string"/>
* </xsd:sequence>
* </xsd:complexType>
* </xsd:element>
* <xsd:element name="phone-number" type="xsd:string"/>
* </xsd:schema>
*
*
*
Code Sample
*
* XMLAnyObjectMapping contactMethodMapping = new XMLAnyObjectMapping();
* contactMethodMapping.setAttributeName("contactMethod");
* contactMethodMapping.setXPath("contact-method");
*
