    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>
