Class ImplicitCollectionFieldMapping

java.lang.Object
  org.apache.shindig.protocol.conversion.xstream.ImplicitCollectionFieldMapping

All Implemented Interfaces:

com.thoughtworks.xstream.mapper.Mapper.ImplicitCollectionMapping

public class ImplicitCollectionFieldMapping
extends Object
implements com.thoughtworks.xstream.mapper.Mapper.ImplicitCollectionMapping

ItemFieldMapping defines a mapping of a class within a class to an element name. Where classes are tested, the must implement or extend the specified classes, unlike the standard behaviour of XStream they dont need to be the classes in question.

The structure is used for implicit collections of the form *

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

or

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

would be specified with NewItemFieldMapping(Person.class, "emails", ListField.class, "emails");
