- Method Detail
  - calculateUnits
```
int calculateUnits(Object oKey,
                   Object oValue)
```
    Calculate a cache cost for the specified cache entry key and value.
    
    Parameters:
    
    oKey - the cache key to evaluate for unit cost
    
    oValue - the cache value to evaluate for unit cost
    
    Returns:
    
    an integer value 0 or greater, with a larger value signifying a higher cost
    
    Throws:
    
    IllegalArgumentException - if any of the specified object types cannot be processed by this calculator
  - getName
```
String getName()
```
    Obtain the name of the unit calculator. This is intended to be human readable for use in a monitoring tool; examples include "SimpleMemoryCalculator" and "BinaryMemoryCalculator".
    
    Returns:
    
    the name of the unit calculator
