Class JAXBIntrospector

  • public abstract class JAXBIntrospector
    extends Object
    Provide access to Jakarta XML Binding xml binding data for a Jakarta XML Binding 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().
