Class JAXBIntrospector

  • Direct Known Subclasses:

    public abstract class JAXBIntrospector
    extends java.lang.Object
    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().
