java.lang.Object
   javax.xml.bind.JAXBIntrospector

JAXBIntrospector
abstract public class JAXBIntrospector (Code)
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 .
See Also:   JAXBContext.createJAXBIntrospector
since:
   JAXB2.0





Method Summary
abstract public  QNamegetElementName(Object jaxbElement)
    

Get xml element qname for jaxbElement.


Parameters:
  jaxbElement - is an object that JAXBIntrospector.isElement(Object) returned true.
public static  ObjectgetValue(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.


Parameters:
  jaxbElement - object that #isElement(Object) returns true.
abstract public  booleanisElement(Object object)
    

Return true iff object represents a JAXB element.

Parameter object is a JAXB element for following cases:

  1. It is an instance of javax.xml.bind.JAXBElement.
  2. The class of object is annotated with @XmlRootElement.



Method Detail
getElementName
abstract public QName getElementName(Object jaxbElement)(Code)

Get xml element qname for jaxbElement.


Parameters:
  jaxbElement - is an object that JAXBIntrospector.isElement(Object) returned true. xml element qname associated with jaxbElement;null if jaxbElement is not a JAXB Element.


getValue
public static Object getValue(Object jaxbElement)(Code)

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.


Parameters:
  jaxbElement - object that #isElement(Object) returns true. The element value of the jaxbElement.


isElement
abstract public boolean isElement(Object object)(Code)

Return true iff object represents a JAXB element.

Parameter object is a JAXB element for following cases:

  1. It is an instance of javax.xml.bind.JAXBElement.
  2. The class of object is annotated with @XmlRootElement.
