public class CollectionAdapter
A CollectionAdapter supports properties whose types implement the java.util.Collection interface.
<property>
<name>People</name>
<xml-name>people</xml-name> <!-- defaults to <name> -->
<type>java.util.Collection</type> <!-- defaults via reflection -->
<class>java.util.LinkedList</class> <!-- defaults to <type> -->
<empty-is-null>true</empty-is-null> <!-- defaults to false -->
<element>
<xml-name>person</xml-name> <!-- optional, nests the elements -->
<type>com...PersonBean</type> <!-- required -->
<adapter>...</adapter> <!-- optional -->
<...> <!-- for the type-specific adapter -->
</element>
</property>
Example of collection nested within collection tags:
<doc>
<people>
<person>
<...>
</person>
<person>
<...>
</person>
