@Provider
public class JAXBElementProvider
extends AbstractJAXBProvider<JAXBElement<?>>

A JAXB Provider which handles parameter and return types of JAXBElement. This provider will be selected when the resource is declared as:

@POST
@Consumes("applictaion/xml")
@Produces("applictaion/xml")
public JAXBElement<Contact> getContact(JAXBElement<Contact> value);

isReadWritable

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

Description copied from class: AbstractJAXBProvider

FIXME Comment this

Specified by:

isReadWritable in class AbstractJAXBProvider<JAXBElement<?>>

Returns:

readFrom

public JAXBElement<?> readFrom(Class<JAXBElement<?>> type,
                      Type genericType,
                      Annotation[] annotations,
                      MediaType mediaType,
                      MultivaluedMap<String,String> httpHeaders,
                      InputStream entityStream)
                        throws IOException

Description copied from interface: MessageBodyReader

Read a type from the InputStream.

Specified by:

readFrom in interface MessageBodyReader<JAXBElement<?>>

Overrides:

readFrom in class AbstractJAXBProvider<JAXBElement<?>>

Parameters:

type - the type that is to be read from the entity stream.

genericType - the type of object to be produced. E.g. if the message body is to be converted into a method parameter, this will be the formal type of the method parameter as returned by Method.getGenericParameterTypes.

annotations - an array of the annotations on the declaration of the artifact that will be initialized with the produced instance. E.g. if the message body is to be converted into a method parameter, this will be the annotations on that parameter returned by Method.getParameterAnnotations.

mediaType - the media type of the HTTP entity.

httpHeaders - the read-only HTTP headers associated with HTTP entity.

entityStream - the InputStream of the HTTP entity. The caller is responsible for ensuring that the input stream ends when the entity has been consumed. The implementation should not close the input stream.

Returns:

the type that was read from the stream.

Throws:

IOException - if an IO error arises

writeTo

public void writeTo(JAXBElement<?> t,
           Class<?> type,
           Type genericType,
           Annotation[] annotations,
           MediaType mediaType,
           MultivaluedMap<String,Object> httpHeaders,
           OutputStream outputStream)
             throws IOException

Description copied from interface: MessageBodyWriter

Write a type to an HTTP response. The response header map is mutable but any changes must be made before writing to the output stream since the headers will be flushed prior to writing the response body.

Specified by:

writeTo in interface MessageBodyWriter<JAXBElement<?>>

Overrides:

writeTo in class AbstractJAXBProvider<JAXBElement<?>>

Parameters:

t - the instance to write.

type - the class of object that is to be written.

genericType - the type of object to be written, obtained either by reflection of a resource method return type or by inspection of the returned instance. GenericEntity provides a way to specify this information at runtime.

annotations - an array of the annotations on the resource method that returns the object.

mediaType - the media type of the HTTP entity.

httpHeaders - a mutable map of the HTTP response headers.

outputStream - the OutputStream for the HTTP entity. The implementation should not close the output stream.

Throws:

IOException - if an IO error arises
