public javax.management.j2ee.statistics.Statistic	getStatistic(java.lang.String str) queries for a Statistic by name. return Statistic return baseStatsImpl.getStatistic(str);
public java.lang.String[]	getStatisticNames() returns an array of names of all the Statistics, that can be retrieved from this implementation of Stats return String[] return baseStatsImpl.getStatisticNames();
public javax.management.j2ee.statistics.Statistic[]	getStatistics() This method can be used to retrieve all the Statistics, exposed by this implementation of Stats return Statistic[] return baseStatsImpl.getStatistics();
