Hello, I am new to castor and have a question about the setting attribute
'base' in the schema file. Using the following as a guide...
<xs:complexType>
<xs:sequence>
<xs:element name="dataset" maxOccurs="unbounded">
<xs:complexType>
<xs:sequence>
<xs:element name="category" maxOccurs="unbounded">
<xs:complexType>
<xs:sequence>
<xs:element name="view" maxOccurs="unbounded">
<xs:complexType>
<xs:complexContent>
<xs:extension base="viewType"/>
</xs:complexContent>
</xs:complexType>
</xs:element>
</xs:sequence>
<xs:attribute name="type" type="xs:string" use="required"/>
</xs:complexType>
</xs:element>
</xs:sequence>
<xs:attribute name="type" type="xs:string" use="required"/>
</xs:complexType>
</xs:element>
</xs:sequence>
</xs:complexType>
Above, there is the <xs:extension base="viewType"/> element, the viewType is
a complexType defined is the schema (not shown here). When I run this schema
through source gen it created ...
class Category {
...
public void addView(com.volant.adapters.pidm.model.configuration.View vView)
throws java.lang.IndexOutOfBoundsException
{
_viewList.addElement(vView);
} //-- void addView(com.volant.adapters.pidm.model.configuration.View)
...
}
... for <xs:element name="category" maxOccurs="unbounded"> which is what was
expected. When I tried to marshal my XML I received a ClassCastException. I
traced the exception to the CategoryDescriptor constructor where it created
a handler for Views ...
handler = (new org.exolab.castor.xml.XMLFieldHandler() {
public java.lang.Object getValue( java.lang.Object object )
throws IllegalStateException
{
Category target = (Category) object;
return target.getView();
}
public void setValue( java.lang.Object object, java.lang.Object
value)
throws IllegalStateException, IllegalArgumentException
{
try {
Category target = (Category) object;
target.addView(
(com.volant.adapters.pidm.model.configuration.View) value);
}
catch (java.lang.Exception ex) {
throw new IllegalStateException(ex.toString());
}
}
public java.lang.Object newInstance( java.lang.Object parent ) {
return new
com.volant.adapters.pidm.model.configuration.View();
}
} );
In the setValue method of the handler there is line of code ...
target.addView( (com.volant.adapters.pidm.model.configuration.View);
Why does the source gen try to cast it to a View? How do I tell the source
gen
To cast it to a ViewType which is the base class of View and instead of
addView(com.volant.adapters.pidm.model.configuration.View vView) it should
be
addView(com.volant.adapters.pidm.model.configuration.ViewType vViewType)
Thanks
J
