Here are two approaches -- I'm sure there are others.
If your subclasses will contain only methods and transient data,
then it is very easy.
If Foo.java and FooDescriptor.java were code generated, then
code this:
public class FooSub extends Foo {
//put your transient stuff here
}
also create one of these:
package same.package.as.FooSub;
//THe class name MUST end in 'Descriptor' and
//start with your subclass name.
public class FooSubDescriptor extends FooDescriptor {
//don't put any code here
}
A second way is to model your hierarcy in the schema.
HEre is an example from Roger Costello's xml schema tutorial:
<xsd:complexType name="Publication">
<xsd:sequence>
<xsd:element name="Title" type="xsd:string"
maxOccurs="unbounded"/>
<xsd:element name="Author" type="xsd:string"
maxOccurs="unbounded"/>
<xsd:element name="Date" type="xsd:gYear"/>
</xsd:sequence>
</xsd:complexType>
<xsd:complexType name="BookPublication">
<xsd:complexContent>
<xsd:extension base="Publication" >
<xsd:sequence>
<xsd:element name="ISBN" type="xsd:string"/>
<xsd:element name="Publisher" type="xsd:string"/>
</xsd:sequence>
</xsd:extension>
</xsd:complexContent>
</xsd:complexType>
Castor will generate these two classes:
public class Publication
public class BookPublication extends Publication
OPtionally, you could move BookPublication to a separate
schema if you want to avoid re-gen'ing on top of your custom code in the
subclass.
