public class ClassFieldMapping
extends Object

This represents the mapping between a class and a field, potentially with a parent element. It is used to define the element names that are used to serialize the contents of a class. eg

 <outerobject>
 <listcontainer>
    <listelement>
       <objectcontent>
    </listelement>
 </listcontainer>
 ...
 </outerobject>
 

or (not currently used in OS)

 <person>
    <emails>
       <email>
          <type></type>
          <value></value>
       </email>
       ...
    </emails>
    ...
 </person>
