      public JAXBElementProvider()

  • Method Details

    • isReadWritable

      protected boolean isReadWritable(Class<?> type, Type genericType, Annotation[] annotations, MediaType mediaType)
      Specified by:
      isReadWritable in class AbstractJAXBProvider<JAXBElement<?>>

    • 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.

      In case the entity input stream is empty, the reader is expected to either return a Java representation of a zero-length entity or throw a NoContentException in case no zero-length entity representation is defined for the supported Java type. A NoContentException, if thrown by a message body reader while reading a server request entity, is automatically translated by JAX-RS server runtime into a BadRequestException wrapping the original NoContentException and rethrown for a standard processing by the registered exception mappers.

      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 instance 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. In case the entity input stream is empty, the reader is expected to either return an instance representing a zero-length entity or throw a NoContentException in case no zero-length entity representation is defined for the supported Java type.
      Throws:
      IOException - if an IO error arises. In case the entity input stream is empty and the reader is not able to produce a Java representation for a zero-length entity, NoContentException is expected to be thrown.

    • 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 message. The message 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 message body.
      Specified by:
      writeTo in interface MessageBodyWriter<JAXBElement<?>>
      Overrides:
      writeTo in class AbstractJAXBProvider<JAXBElement<?>>
      Parameters:
      t - the instance to write.
      type - the class of instance that is to be written.
      genericType - the type of instance to be written. GenericEntity provides a way to specify this information at runtime.
      annotations - an array of the annotations attached to the message entity instance.
      mediaType - the media type of the HTTP entity.
      httpHeaders - a mutable map of the HTTP message headers.
      outputStream - the OutputStream for the HTTP entity. The implementation must not close the output stream.
      Throws:
      IOException - if an IO error arises.

    • asyncWriteTo

      public CompletionStage<Void> asyncWriteTo(JAXBElement<?> t, Class<?> type, Type genericType, Annotation[] annotations, MediaType mediaType, MultivaluedMap<String,Object> httpHeaders, AsyncOutputStream outputStream)
      Description copied from interface: AsyncMessageBodyWriter
      Write a type to an HTTP message using async IO. The message header map is mutable but any changes must be made before writing to the async output stream since the headers will be flushed prior to writing the message body.
      Parameters:
      t - the instance to write.
      type - the class of instance that is to be written.
      genericType - the type of instance to be written. GenericEntity provides a way to specify this information at runtime.
      annotations - an array of the annotations attached to the message entity instance.
      mediaType - the media type of the HTTP entity.
      httpHeaders - a mutable map of the HTTP message headers.
      outputStream - the AsyncOutputStream for the HTTP entity. The implementation should not close the output stream.
      Returns:
      a CompletionStage indicating completion
