javax.xml.bind

Provides a runtime binding framework for client applications including unmarshalling, marshalling, and validation capabilities.

JAXBContext is the client-entry point to the runtime binding framework.

An instance of this class maintains the association between XML nodes of an infoset preserving view and a JAXB representation of an XML document.

The javaType binding declaration can be used to customize the binding of an XML schema datatype to a Java datatype.

The DatatypeConverterInterface is for JAXB provider use only.

Methods defined in this class are convenience methods that combine several basic operations in the JAXBContext , Unmarshaller , and Marshaller . They are designed to be the prefered methods for developers new to JAXB.

The JAXBContext class provides the client's entry point to the JAXB API.

JAXB representation of an Xml Element.

This class represents information about an Xml Element from both the element declaration within a schema and the element instance value within an xml document with the following properties

• element's xml tag name
• value represents the element instance's atttribute(s) and content model
• element declaration's declaredType (xs:element @type attribute)
• scope of element declaration
• boolean nil property.

The ValidationEventHandler can cause this exception to be thrown during the marshal operations.

The Marshaller class is responsible for governing the process of serializing Java content trees back into XML data.

This exception can be thrown by the generated setter methods of the schema derived Java content classes.

The ValidationEventHandler can cause this exception to be thrown during the unmarshal operations.

Applications can use this interface to use their JAXB provider as a component in an XML pipeline.

If an application needs to implement customized event handling, it must implement this interface and then register it with either the Unmarshaller.setEventHandler(ValidationEventHandler) Unmarshaller , the Validator.setEventHandler(ValidationEventHandler) Validator , or the Marshaller.setEventHandler(ValidationEventHandler) Marshaller .

The ValidationEventLocator indicates where the ValidationEvent occurred.

The ValidationEventHandler can cause this exception to be thrown during the validate operations.

The Validator class is responsible for controlling the validation of content trees during runtime.

Three Forms of Validation

Unmarshal-Time Validation

This form of validation enables a client application to receive information about validation errors and warnings detected while unmarshalling XML data into a Java content tree and is completely orthogonal to the other types of validation.
