    • MessageChunksBuffer

      public MessageChunksBuffer(int maxContentLength, int allChunksTimeout, int maxChunks)
      Creates a new instance.
      Parameters:
      maxContentLength - the maximum cumulative length of the aggregated message. If the length of the buffered content exceeds this value, a {@link TooLongFrameException)} will be thrown.
      allChunksTimeout - time in milliseconds after receiving the first chunk to wait for remaining chunks. Upon timeout, received chunks will be discarded. A value of 0 deactivates the timeout function.
      maxChunks - maximum number of chunks to collect. If the more chunks are required to aggregate the message, all chunks will be discarded.
