question: public void addRecord ( String messageId , int i , double d ) { if ( m_msgData == null ) { m_msgData = new TreeMap < String , LogNormalScore . MsgData > ( ) ; m_minLambda = 1 ; } final MsgData data = new MsgData ( ) ; data . m_totalLogCounts = i ; data . m_lambda = d ; m_msgData . put ( messageId , data ) ; m_minLambda = Math . min ( data . m_lambda , m_minLambda ) ; m_totalIntervalCount = 1 ; }
target:  Add in a new record i.e. a new MsgData into the mapping.
