/**
 * Implementation {@link StatisticInfo} This does not contains associated

 * 
 * This has been created client(E.g GFMon2.0), where we actually don't need

 * can reduce the overhead of data transfer across network and
 * serialization/dserialization
 * 
 * on server side , {@link StatAlertsManager} create instance of
 * {@link StatisticInfoImpl} class with help of this class instance
