public CacheRegionStatisticsImpl getCacheRegionStatistics(String regionName)
```
    Description copied from interface: Statistics
    Obtain the statistics for either a domain data or query result cache region.
    This method checks both, preferring the domain data region if there is one. Think of it as a cascading check to:
    
    Statistics.getDomainDataRegionStatistics(java.lang.String)
    
    Statistics.getQueryRegionStatistics(java.lang.String)
    
    Note that null is returned instead of throwing an exception when no region exists with the given name.
    Specified by:
    
    getCacheRegionStatistics in interface Statistics
    
    Parameters:
    
    regionName - The unqualified region name
    
    Returns:
    
    the statistics for the named region, or null if there is no region with the given name
