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

org.glassfish.jersey.jaxb.internal.AbstractJaxbProvider<JAXBElement<?>>

org.glassfish.jersey.jaxb.internal.AbstractJaxbElementProvider

All Implemented Interfaces:

MessageBodyReader<JAXBElement<?>>, MessageBodyWriter<JAXBElement<?>>

Direct Known Subclasses:

XmlJaxbElementProvider

public abstract class AbstractJaxbElementProvider
extends AbstractJaxbProvider<JAXBElement<?>>

An abstract provider for JAXBElement.

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).

Method Detail

isReadable

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

isWriteable

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

readFrom

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

Throws:

IOException

readFrom

protected abstract JAXBElement<?> readFrom(Class<?> type,
                                           MediaType mediaType,
                                           Unmarshaller unmarshaller,
                                           InputStream entityStream)
                                    throws JAXBException

Read JAXB element from an entity stream.

Parameters:

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

mediaType - the media type of the HTTP entity.

unmarshaller - JAXB unmarshaller to be used.

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:

JAXB element representing the entity.

Throws:

JAXBException - in case entity unmarshalling fails.

writeTo

public final void writeTo(JAXBElement<?> t,
                          Class<?> type,
                          Type genericType,
                          Annotation[] annotations,
                          MediaType mediaType,

                          OutputStream entityStream)
                   throws IOException

Throws:

IOException

writeTo

protected abstract void writeTo(JAXBElement<?> element,
                                MediaType mediaType,
                                Charset charset,
                                Marshaller marshaller,
                                OutputStream entityStream)
                         throws JAXBException

Write JAXB element to an entity stream.

Parameters:

element - JAXB element to be written to an entity stream.

mediaType - the media type of the HTTP entity.

charset - character set to be used.

marshaller - JAXB unmarshaller to be used.

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.

Throws:

JAXBException - in case entity marshalling fails.
