public LocalIndexStatsImpl()
```
- Method Detail
  - getCreationTime
```
public long getCreationTime()
```
    Description copied from interface: LocalInstanceStats
    
    Returns the creation time of this distributed object instance on this member.
    
    Specified by:
    
    getCreationTime in interface LocalInstanceStats
  - setCreationTime
```
public void setCreationTime(long creationTime)
```
    Sets the creation of this stats to the given creation time.
    
    Parameters:
    
    creationTime - the creation time to set.
  - getQueryCount
```
public long getQueryCount()
```
    Description copied from interface: LocalIndexStats
    
    Returns the total number of queries served by the index.
    To calculate the index hit rate just divide the returned value by a value returned by LocalMapStats.getQueryCount().
    The returned value may be less than the one returned by LocalIndexStats.getHitCount() since a single query may hit the same index more than once.
    
    Specified by:
    
    getQueryCount in interface LocalIndexStats
  - setQueryCount
```
public void setQueryCount(long queryCount)
```
    Sets the query count of this stats to the given query count.
    
    Parameters:
    
    queryCount - the query count to set.
  - getHitCount
```
public long getHitCount()
```
    Description copied from interface: LocalIndexStats
    
    Returns the total number of hits into the index.
    The returned value may be greater than the one returned by LocalIndexStats.getQueryCount() since a single query may hit the same index more than once.
    
    Specified by:
    
    getHitCount in interface LocalIndexStats
  - setHitCount
```
public void setHitCount(long hitCount)
```
    Sets the hit count of this stats to the given hit count.
    
    Parameters:
    
    hitCount - the hit count to set.
  - getAverageHitLatency
```
public long getAverageHitLatency()
```
    Description copied from interface: LocalIndexStats
    
    Returns the average hit latency (in nanoseconds) for the index.
    
    Specified by:
    
    getAverageHitLatency in interface LocalIndexStats
  - setAverageHitLatency
```
public void setAverageHitLatency(long averageHitLatency)
```
    Sets the average hit latency of this stats to the given average hit latency.
    
    Parameters:
    
    averageHitLatency - the average hit latency to set.
  - getAverageHitSelectivity
```
public double getAverageHitSelectivity()
```
    Description copied from interface: LocalIndexStats
    
    Returns the average selectivity of the hits served by the index.
    The returned value is in the range from 0.0 to 1.0. Values close to 1.0 indicate a high selectivity meaning the index is efficient; values close to 0.0 indicate a low selectivity meaning the index efficiency is approaching an efficiency of a simple full scan.
    
    Specified by:
    
    getAverageHitSelectivity in interface LocalIndexStats
  - setAverageHitSelectivity
```
public void setAverageHitSelectivity(double averageHitSelectivity)
