Methods Summary
void	executed(long rows, long time) add statistics report of a DB query param rows rows count returned param time time taken if (time < executionMinTime) executionMinTime = time; if (time > executionMaxTime) executionMaxTime = time; executionAvgTime = ( executionAvgTime * executionCount + time ) / ( executionCount + 1 ); executionCount++; executionRowCount += rows;
public long	getCacheHitCount() Queries retrieved successfully from the cache return cacheHitCount;
public long	getCacheMissCount() return cacheMissCount;
public long	getCachePutCount() return cachePutCount;
public long	getExecutionAvgTime() average time in ms taken by the excution of this query onto the DB return executionAvgTime;
public long	getExecutionCount() queries executed to the DB return executionCount;
public long	getExecutionMaxTime() max time in ms taken by the excution of this query onto the DB return executionMaxTime;
public long	getExecutionMinTime() min time in ms taken by the excution of this query onto the DB return executionMinTime;
public long	getExecutionRowCount() Number of lines returned by all the executions of this query (from DB) For now, {@link org.hibernate.Query#iterate()} and {@link org.hibernate.Query#scroll()()} do not fill this statistic return The number of rows cumulatively returned by the given query; iterate and scroll queries do not effect this total as their number of returned rows is not known at execution time. return executionRowCount;
