org.glassfish.jersey.message.internal.AbstractMessageReaderWriterProvider<T>

org.glassfish.jersey.jaxb.internal.AbstractJaxbProvider<Object>

org.glassfish.jersey.jaxb.internal.AbstractRootElementJaxbProvider

All Implemented Interfaces:

MessageBodyReader<Object>, MessageBodyWriter<Object>

Direct Known Subclasses:

JettisonRootElementProvider, XmlRootElementJaxbProvider

public abstract class AbstractRootElementJaxbProvider
extends AbstractJaxbProvider<Object>

An abstract provider for JAXB types that are annotated with XmlRootElement or XmlType.

Implementing classes may extend this class to provide specific marshalling and unmarshalling behaviour.

When unmarshalling a UnmarshalException will result in a WebApplicationException being thrown with a status of 400 (Client error), and a JAXBException will result in a WebApplicationException being thrown with a status of 500 (Internal Server error).

When marshalling a JAXBException will result in a WebApplicationException being thrown with a status of 500 (Internal Server error).

isWriteable

public boolean isWriteable(Class<?> type,
                           Type genericType,
                           Annotation[] annotations,
                           MediaType mediaType)

readFrom

public final Object readFrom(Class<Object> type,
                             Type genericType,
                             Annotation[] annotations,

                             InputStream inputStream)
                      throws IOException

Throws:

IOException

readFrom

protected Object readFrom(Class<Object> type,
                          MediaType mediaType,
                          Unmarshaller u,
                          InputStream entityStream)
                   throws JAXBException

Unmarshal a JAXB type.

Implementing classes may override this method.

Parameters:

type - the JAXB type

mediaType - the media type

u - the unmarshaller to use for unmarshalling.

entityStream - the input stream to unmarshal from.

Returns:

an instance of the JAXB type.

Throws:

JAXBException - in case the JAXB unmarshalling fails.

writeTo

                          OutputStream entityStream)
                   throws IOException

Throws:

IOException

writeTo

protected void writeTo(Object t,
                       MediaType mediaType,
                       Charset c,
                       Marshaller m,
                       OutputStream entityStream)
                throws JAXBException

Marshal an instance of a JAXB type.

Implementing classes may override this method.

Parameters:

t - the instance of the JAXB type.

mediaType - the media type.

c - the character set to serialize characters to.

m - the marshaller to marshaller the instance of the JAXB type.

entityStream - the output stream to marshal to.

Throws:

JAXBException - in case the JAXB marshalling fails.
