- org.hibernate.stat.internal.QueryStatisticsImpl

所有已实现的接口:

Serializable, QueryStatistics
```

extends Object
implements QueryStatistics
```

修饰符和类型	方法	说明
`long`	`getCacheHitCount()`	Queries retrieved successfully from the cache
`long`	`getCacheMissCount()`	The number of cache misses for this query
`long`	`getCachePutCount()`	The number of cache puts for this query
`long`	`getExecutionAvgTime()`	average time in ms taken by the execution of this query onto the DB

  - getExecutionCount
```
public long getExecutionCount()
```
    queries executed to the DB
    
    指定者:
    
    getExecutionCount 在接口中 QueryStatistics
  - getCacheHitCount
```
public long getCacheHitCount()
```
    Queries retrieved successfully from the cache
    
    指定者:
    
    getCacheHitCount 在接口中 QueryStatistics
  - getCachePutCount
```
public long getCachePutCount()
```
    从接口复制的说明: QueryStatistics
    
    The number of cache puts for this query
    
    指定者:
    
    getCachePutCount 在接口中 QueryStatistics
  - getCacheMissCount
```
public long getCacheMissCount()
```
    从接口复制的说明: QueryStatistics
    
    The number of cache misses for this query
    
    指定者:
    
    getCacheMissCount 在接口中 QueryStatistics
  - getExecutionRowCount
```
public long getExecutionRowCount()
```
    Number of lines returned by all the executions of this query (from DB) For now, Query.iterate() and {@link org.hibernate.Query#scroll()()} do not fill this statistic
    
    指定者:
    
    getExecutionRowCount 在接口中 QueryStatistics
    
    返回:
    
    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.
  - getExecutionAvgTime
```
public long getExecutionAvgTime()
```
    average time in ms taken by the execution of this query onto the DB
    
    指定者:
    
    getExecutionAvgTime 在接口中 QueryStatistics

```
public double getExecutionAvgTimeAsDouble()
```
    average time in ms as double taken by the execution of this query onto the DB
    
    指定者:
    
    getExecutionAvgTimeAsDouble 在接口中 QueryStatistics
  - getExecutionMaxTime
```
public long getExecutionMaxTime()
```

    指定者:
    
    getExecutionMaxTime 在接口中 QueryStatistics
  - getExecutionMinTime
```
public long getExecutionMinTime()
```
    min time in ms taken by the execution of this query onto the DB
    
    指定者:
    
    getExecutionMinTime 在接口中 QueryStatistics
  - getExecutionTotalTime
```
public long getExecutionTotalTime()
```
    total time in ms taken by the execution of this query onto the DB
    
    指定者:
    
    getExecutionTotalTime 在接口中 QueryStatistics
  - getPlanCacheHitCount
```
public long getPlanCacheHitCount()
```
    Query plan successfully fetched from the cache
    
    指定者:
    
    getPlanCacheHitCount 在接口中 QueryStatistics
  - getPlanCacheMissCount
```
public long getPlanCacheMissCount()
```
    Query plan not fetched from the cache
    
    指定者:
    
    getPlanCacheMissCount 在接口中 QueryStatistics
  - getPlanCompilationTotalMicroseconds
```
public long getPlanCompilationTotalMicroseconds()

    Query plan overall compiled total
    
    指定者:
    
    getPlanCompilationTotalMicroseconds 在接口中 QueryStatistics
  - toString
```
public String toString()
```
    覆盖:
