javax.xml.bind Class JAXBIntrospector

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

---

public abstract class JAXBIntrospector

extends 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().

从以下版本开始:

JAXB2.0
