    • closeAsync

      public CompletableFuture<Void> closeAsync()
      Specified by:

    • getCnxIfReady

      protected ClientCnx getCnxIfReady()
      Hook method for testing. By returning null, it's possible to prevent messages being delivered to the broker.
      Returns:
      cnx if OpSend messages should be written to open connection. Caller must verify that the returned cnx is not null before using reference.

    • recoverChecksumError

      protected void recoverChecksumError(ClientCnx cnx, long sequenceId)
      Checks message checksum to retry if message was corrupted while sending to broker. Recomputes checksum of the message header-payload again.
      • if matches with existing checksum: it means message was corrupt while sending to broker. So, resend message
      • if doesn't match with existing checksum: it means message is already corrupt and can't retry again. So, fail send-message by failing callback
      Parameters:
      cnx -
      sequenceId -

    • recoverNotAllowedError

      protected void recoverNotAllowedError(long sequenceId, String errorMsg)

    • verifyLocalBufferIsNotCorrupted

      protected boolean verifyLocalBufferIsNotCorrupted(ProducerImpl.OpSendMsg op)
      Computes checksum again and verifies it against existing checksum. If checksum doesn't match it means that message is corrupt.
      Parameters:
      op -
      Returns:
      returns true only if message is not modified and computed-checksum is same as previous checksum else return false that means that message is corrupted. Returns true if checksum is not present.
