Examples of org.springframework.messaging.simp.stomp.BufferingStompDecoder.decode()

org.springframework.messaging.simp.stomp.BufferingStompDecoder.decode()

Decodes one or more STOMP frames from the given {@code ByteBuffer} into alist of {@link Message}s.

If there was enough data to parse a "content-length" header, then the value is used to determine how much more data is needed before a new attempt to decode is made.

If there was not enough data to parse the "content-length", or if there is "content-length" header, every subsequent call to decode attempts to parse again with all available data. Therefore the presence of a "content-length" header helps to optimize the decoding of large messages. @param newBuffer a buffer containing new data to decode @return decoded messages or an empty list @throws StompConversionException raised in case of decoding issues

      BufferingStompDecoder decoder = this.decoders.get(session.getId());
      if (decoder == null) {
        throw new IllegalStateException("No decoder for session id '" + session.getId() + "'");
      }


      messages = decoder.decode(byteBuffer);
      if (messages.isEmpty()) {
        if (logger.isTraceEnabled()) {
          logger.trace("Incomplete STOMP frame content received in session " +
              session + ", bufferSize=" + decoder.getBufferSize() +
              ", bufferSizeLimit=" + decoder.getBufferSizeLimit() + ".");
