public abstract class JAXBIntrospector extends 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()
.
JAXBContext.createJAXBIntrospector()
