    • isHeaderValid

      public boolean isHeaderValid(AmqpHeader header, boolean authenticated)
      Given an AMQP header validate that the AMQP magic is present and if so that the version and protocol values align with what we support. In the case where authentication occurs the client sends us two AMQP headers, the first being the SASL initial header which triggers the authentication process and then if that succeeds we should get a second AMQP header that does not contain the SASL protocol ID indicating the connection process should follow the normal path. We validate that the header align with these expectations.
      Parameters:
      header - the header instance received from the client.
      authenticated - has the client already authenticated already.
      Returns:
      true if the header is valid against the current WireFormat.

    • getMinimallySupportedHeader

      public AmqpHeader getMinimallySupportedHeader()
      Returns an AMQP Header object that represents the minimally protocol versions supported by this transport. A client that attempts to connect with an AMQP version that doesn't at least meat this value will receive this prior to the connection being closed.
      Returns:
      the minimal AMQP version needed from the client.
