abstract long org.objectweb.cjdbc.common.monitor.cache.AbstractCacheStatsDataCollector.getValue (  Object  cache  )  [pure virtual]
 

We have the cache object so let's get the value we want from ot

Parameters:
cache as an object to allow it through RMI, but IS a AbstractResultCache
Returns:
the collected value

Implemented in org.objectweb.cjdbc.common.monitor.cache.CacheEntriesCollector, org.objectweb.cjdbc.common.monitor.cache.CountHitsCollector, org.objectweb.cjdbc.common.monitor.cache.CountInsertCollector, org.objectweb.cjdbc.common.monitor.cache.CountSelectCollector, and org.objectweb.cjdbc.common.monitor.cache.HitsRatioCollector.
