/**
 * 

Composite object XML mappings represent a relationship between two classes. In XML, the "owned" * class may be nested with the element tag representing the "owning" class. This mapping is, by * definition, privately owned. * *

Composite object XML mappings can be used in the following scenarios:

    *
  • Mapping into the Parent Record
  • *
  • Mapping to an Element
  • *
  • Mapping to Different Elements by Element Name
  • *
  • Mapping to Different Elements by Element Position
  • *
* *

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 path and positional information; the last node in the XPath forms the local * root node for the composite object. The XPath is specified on the mapping using the setXPath * method. * *

The following XPath statements may be used to specify the location of XML data relating to an object's * name attribute: * *

* * * * * * * * * * * * * * * * * * * * *
XPathDescription
.Indicates "self".
phone-numberThe phone-number information is stored in the phone-number element.
contact-info/phone-numberThe XPath statement may be used to specify any valid path.
phone-number[2]The XPath statement may contain positional information. In this case the phone-number * information is stored in the second occurrence of the phone-number element.
* *

Mapping into the Parent Record: The composite object may be mapped into the parent * record in a corresponding XML document. * * * *

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="first-name" type="xsd:string"/>
*       <xsd:element name="last-name" type="xsd:string"/>
*       <xsd:element name="street" type="xsd:string"/>
*       <xsd:element name="city" type="xsd:string"/>
*     </xsd:sequence>
*   </xsd:complexType>
* </xsd:schema> *
* *

Code Sample
* * XMLCompositeObjectMapping addressMapping = new XMLCompositeObjectMapping();
* addressMapping.setAttributeName("address");
* addressMapping.setXPath(".");
* addressMapping.setReferenceClass(Address.class);
*
* *

Mapping to an Element: The composite object may be mapped to an element in a corresponding * XML document. * * * *

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="first-name" type="xsd:string"/>
*       <xsd:element name="last-name" type="xsd:string"/>
*       <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:sequence>
*   </xsd:complexType>
* </xsd:schema>

* * XMLCompositeObjectMapping addressMapping = new XMLCompositeObjectMapping();

* addressMapping.setXPath("address");
