Although I can not see how this information in the super class is used, I
accept that it could be useful during marshalling/unmarshalling. Thanks for
the explanation.
I would also like to bring up a question posted in an earlier mail on a
different topic (JavaNaming). This time I'll ask the question in a different
way:
Suppose the xsd is:
...
<xsd:complexType name="top" abstract ="true">
<xsd:sequence min occurs="0" maxOccurs="unbounded">
<xsd:element name="text" type="xsd:string">
<xsd:element name="price" type="xsd:decimal">
</xsd:sequence>
</xsd:complexType>
<xsd:complexType name="derived">
<xsd:complexContent>
<xsd:extension base="top">
<xsd:sequence min occurs="0" maxOccurs="unbounded">
<xsd:element name="discount" type="xsd:decimal">
</xsd:sequence>
</xsd:complexContent>
</xsd:complexType>
<xsd:element name="Store">
<xsd;complexType>
<xsd:sequence>
<xsd:element name="item" maxOccurs="unbounded" type="top">
</xsd:sequence>
</xsd:complexType>
</sxd:complexType>
Suppose one xml based on the above xsd is:
...
<Store ...>
<item xsi:type="derived">
<text>BottleOfJellyBeans</text>
<price>1</text>
</item>
<item xsd:type="derived">
<text>Jam</text>
<price>3</text>
<discount>0.20</discount>
</item>
</Store>
I would expect that instances of "derived" class will be instantiated when
the above xml is being unmarshalled. However, the unmarshal code actually
instantiates a "top" class. Do I miss something here?
Thanks,
Wei
