    • isWriteable

      public boolean isWriteable(Class<?> type, Type genericType, Annotation[] annotations, MediaType mediaType)
      Description copied from interface: MessageBodyWriter
      Ascertain if the MessageBodyWriter supports a particular type.
      Specified by:
      isWriteable in interface MessageBodyWriter<List<EntityPart>>
      Parameters:
      type - the class of instance that is to be written.
      genericType - the type of instance to be written, obtained either by reflection of a resource method return type or via inspection of the returned instance. 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.
      Returns:
      true if the type is supported, otherwise false.
    • writeTo

      public void writeTo(List<EntityPart> entityParts, Class<?> type, Type genericType, Annotation[] annotations, MediaType mediaType, MultivaluedMap<String,Object> httpHeaders, OutputStream entityStream) throws IOException, WebApplicationException
      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<List<EntityPart>>
      Parameters:
      entityParts - 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.
      entityStream - the OutputStream for the HTTP entity. The implementation must not close the output stream.
      Throws:
      IOException - if an IO error arises.
      WebApplicationException - if a specific HTTP error response needs to be produced. Only effective if thrown prior to the message being committed.
    • asyncWriteTo

      public CompletionStage<Void> asyncWriteTo(List<EntityPart> entityParts, Class<?> type, Type genericType, Annotation[] annotations, MediaType mediaType, MultivaluedMap<String,Object> httpHeaders, AsyncOutputStream entityStream)
      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.
      Specified by:
      asyncWriteTo in interface AsyncMessageBodyWriter<List<EntityPart>>
      Parameters:
      entityParts - 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.
      entityStream - the AsyncOutputStream for the HTTP entity. The implementation should not close the output stream.
      Returns:
      a CompletionStage indicating completion
