Hi all,
Suppose I have an XML Schema with (among others) a declaration like
<xs:complexType name="foobar">
<xs:sequence>
<xs:element name="a" type="xs:int"/>
<xs:element name="b" type="xs:int" minOccurs="0"/>
</xs:sequence>
</xs:complexType>
From this, JAXB generates the interface Foobar
public interface Foobar {
int getA();
void setA(int value);
int getB();
void setB(int value);
}
with a matching implementation in FoobarImpl. When I unmarshal XML documents
based on this schema they will always contain an <a> element and may or may
not contain a <b> element.
My question is: Given a Foobar instance, how do I determine wether or not
element <b> occurred in a document?
FYI, for the same schema, Apache Axis will generate a Java class for <foobar>
which maps <b> to java.lang.Integer, allowing the getter to return null when
<b> does not occur in the unmarshalled document.
Kind regards,
Jacob
