    • verifyHostName

      protected boolean verifyHostName

    • trace

      protected boolean trace
      trace=true -> the Transport stack where this TcpTransport object will be, will have a TransportLogger layer trace=false -> the Transport stack where this TcpTransport object will be, will NOT have a TransportLogger layer, and therefore will never be able to print logging messages. This parameter is most probably set in Connection or TransportConnector URIs.

      protected String logWriterName
      Name of the LogWriter implementation to use. Names are mapped to classes in the resources/META-INF/services/org/apache/activemq/transport/logwriters directory. This parameter is most probably set in Connection or TransportConnector URIs.

    • dynamicManagement

      protected boolean dynamicManagement
      Specifies if the TransportLogger will be manageable by JMX or not. Also, as long as there is at least 1 TransportLogger which is manageable, a TransportLoggerControl MBean will me created.

    • startLogging

      protected boolean startLogging
      startLogging=true -> the TransportLogger object of the Transport stack will initially write messages to the log. startLogging=false -> the TransportLogger object of the Transport stack will initially NOT write messages to the log. This parameter only has an effect if trace == true. This parameter is most probably set in Connection or TransportConnector URIs.
