public abstract class JAXBIntrospector
extends java.lang.Object
Initially, the intent of this class is to just conceptualize how
a Jakarta XML Binding 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 Jakarta XML Binding element is
a highly requested feature, demonstrate access to this
binding information.
The factory method to get a JAXBIntrospector instance is
JAXBContext.createJAXBIntrospector().

protected JAXBIntrospector()
public abstract boolean isElement(java.lang.Object object)
Return true if object represents a Jakarta XML Binding element.
Parameter object is a Jakarta XML Binding element for following cases:
jakarta.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 JAXBElement.public static java.lang.Object getValue(java.lang.Object jaxbElement)
Get the element value of a Jakarta XML Binding element.
Convenience method to abstract whether working with either
a jakarta.xml.bind.JAXBElement instance or an instance of
@XmlRootElement annotated Java class.
jaxbElement - object that #isElement(Object) returns true.jaxbElement.
