All Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`void`	`executed(long rows, long time)`	add statistics report of a DB query
`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
`double`	`getExecutionAvgTimeAsDouble()`	average time in ms as double taken by the execution of this query onto the DB
`long`	`getExecutionCount()`	queries executed to the DB

public QueryStatisticsImpl(String query)
```
- Method Detail
  - getExecutionCount
```
public long getExecutionCount()
```
    queries executed to the DB
    
    Specified by:
    
    getExecutionCount in interface QueryStatistics
  - getCacheHitCount
```
public long getCacheHitCount()
```
    Queries retrieved successfully from the cache
    
    Specified by:
    
    getCacheHitCount in interface QueryStatistics
  - getCachePutCount
```
public long getCachePutCount()
```
    Description copied from interface: QueryStatistics
    
    The number of cache puts for this query
    
    Specified by:
    
    getCachePutCount in interface QueryStatistics
  - getCacheMissCount
```
public long getCacheMissCount()
```
    Description copied from interface: QueryStatistics
    
    The number of cache misses for this query
    
    Specified by:
    
    getCacheMissCount in interface QueryStatistics
  - getExecutionRowCount
```
public long getExecutionRowCount()
```
    Number of lines returned by all the executions of this query (from DB) For now, Query.stream()} and Query.scroll() do not fill this statistic
    
    Specified by:
    
    getExecutionRowCount in interface QueryStatistics
    
    Returns:
    
    The number of rows cumulatively returned by the given query; stream and scroll queries do not effect this total as their number of returned rows is not known at execution time.
