java.lang.Object javax.xml.bind.JAXBIntrospector
public abstract class JAXBIntrospector
Provide access to JAXB xml binding data for a JAXB object.
Intially, the intent of this class is to just conceptualize how
a JAXB application developer can access xml binding information,
independent if binding model is java to schema or schema to java.
Since accessing the XML element name related to a JAXB element is
a highly requested feature, demonstrate access to this
binding information.
The factory method to get a JAXBIntrospector
instance is
JAXBContext.createJAXBIntrospector()
.

public abstract boolean isElement(java.lang.Object object)
Return true iff object
represents a JAXB element.
Parameter object
is a JAXB element for following cases:
javax.xml.bind.JAXBElement
.object
is annotated with
@XmlRootElement
.
getElementName(Object)
public abstract javax.xml.namespace.QName getElementName(java.lang.Object jaxbElement)
Get xml element qname for jaxbElement
.
jaxbElement
- is an object that isElement(Object)
returned true.
jaxbElement
is not a JAXB Element.public static java.lang.Object getValue(java.lang.Object jaxbElement)
Get the element value of a JAXB element.
Convenience method to abstract whether working with either a javax.xml.bind.JAXBElement instance or an instance of @XmlRootElement annotated Java class.
jaxbElement
- object that #isElement(Object) returns true.
