public class ArrayAdapter

extends IterableAdapter

An ArrayAdapter supports properties of Java array types (not including arrays of primitive types).

 <property>
   <name>People</name>
   <xml-name>people</xml-name>         <!-- defaults to <name> -->
   <type>com...Person[]</type>         <!-- defaults via reflection -->
   <class>com...Person[]</class>       <!-- defaults from <type> -->
   <sparse>true</sparse>               <!-- defaults to false -->
   <empty-is-null>true</empty-is-null> <!-- defaults to false -->
   <element>                           <!-- optional -->
     <xml-name>person</xml-name>       <!-- optional, nests the elements -->
     <type>com...Person</type>         <!-- auto-set from <property><class> -->
     <adapter>...</adapter>            <!-- optional -->
     <...>                             <!-- for the type-specific adapter -->
   </element>
 </property>
 

Example of collection nested within collection tags:

   <doc>
     <people>
       <person>
         <...>
       </person>
       <person>
         <...>
       </person>
       ...
     </people>
   </doc>
