public class MapAdapter
- extends IterableAdapter
A MapAdapter supports properties whose types implement the java.util.Map interface.
<property>
<name>People</name>
<xml-name>people</xml-name> <!-- defaults to <name> -->
<type>java.util.Map</type> <!-- defaults via reflection -->
<class>java.util.HashMap</class> <!-- defaults to <type> -->
<empty-is-null>true</empty-is-null> <!-- defaults to false -->
<element>
<xml-name>person</xml-name> <!-- required -->
<key>
<name>ssn</name> <!-- defaults to "key" -->
<xml-name>ssn</xml-name> <!-- defaults to <name> -->
<type>String</type> <!-- required -->
<adapter>...</adapter> <!-- optional -->
<...> <!-- for the type-specific adapter -->
</key>
<value>
<name>info</name> <!-- defaults to "value" -->
<xml-name>info</xml-name> <!-- defaults to <name> -->
<type>com...PersonBean</type> <!-- required -->
<adapter>...</adapter> <!-- optional -->
<...> <!-- for the type-specific adapter -->
</value>
</elelemt>
</property>
Example of map nested within collection tags:

<ssn>...</ssn>
<info>...</info>
</person>
<person>
<ssn>...</ssn>
<info>...</info>
</person>
...
