internal long Login()
        {
            _loginReqMsg = (ReqMsg) new LoginMessage(this.connection.Config).Create();
            _ommItemIntSpecLogin = new OMMItemIntSpec { Msg = new LoginMessage(this.connection.Config).Create() };

        }
        internal void Pause(long loginHandle)
        {
            _loginReqMsg.InteractionType = ReqMsg.InteractionTypeFlag.Pause;
            _ommItemIntSpecLogin.Msg = _loginReqMsg;
            connection.OmmConsumer.ReissueClient(loginHandle, _ommItemIntSpecLogin);
        }
        internal void Resume(long loginHandle)
        {
            _loginReqMsg.InteractionType = ReqMsg.InteractionTypeFlag.InterestAfterRefresh;
            _ommItemIntSpecLogin.Msg = _loginReqMsg;
            connection.OmmConsumer.ReissueClient(loginHandle,_ommItemIntSpecLogin);
        }
