    Description copied from interface: Statistics

    Parameters:

```
public CacheRegionStatisticsImpl getCacheRegionStatistics(String regionName)
```
    Description copied from interface: Statistics
    Get statistics for either a domain-data or query-result region - this method checks both, preferring domain data region if one. Think of it as a cascading check to:
    1. Statistics.getDomainDataRegionStatistics(java.lang.String)
    2. Statistics.getQueryRegionStatistics(java.lang.String)
    Note that returning null is preferred here over throwing an exception when no region exists with that name.
    Specified by:
    
    getCacheRegionStatistics in interface Statistics
    
    Parameters:
    
    regionName - The unqualified region name
    
    Returns:
    
    Stats for the named region, or null if no such region exists
