Java Source Code / Java Documentation » Cache » OSCache » com.opensymphony.oscache.extra   Source Cross Reference   Class Diagram   Java Document (Java Doc)   java.lang.Object    com.opensymphony.oscache.extra.StatisticListenerImpl StatisticListenerImpl public class StatisticListenerImpl implements CacheMapAccessEventListener,CacheEntryEventListener,ScopeEventListener(Code) A simple implementation of a statistic reporter which uses the event listeners. It uses the events to count the cache hit and misses and of course the flushes. We are not using any synchronized so that this does not become a bottleneck. The consequence is that on retrieving values, the operations that are currently being done won't be counted. Constructor Summary public   StatisticListenerImpl()      Constructor, empty for us. Method Summary public  void accessed(CacheMapAccessEvent event)      This method handles an event each time the cache is accessed. public  void cacheEntryAdded(CacheEntryEvent event)      Event fired when an entry is added to the cache. public  void cacheEntryFlushed(CacheEntryEvent event)      Event fired when an entry is flushed from the cache. public  void cacheEntryRemoved(CacheEntryEvent event)      Event fired when an entry is removed from the cache. public  void cacheEntryUpdated(CacheEntryEvent event)      Event fired when an entry is updated in the cache. public  void cacheFlushed(CachewideEvent event)      An event that is fired when an entire cache gets flushed. public  void cacheGroupFlushed(CacheGroupEvent event)      Event fired when a group is flushed from the cache. public  void cachePatternFlushed(CachePatternEvent event)      Event fired when a key pattern is flushed from the cache. public  int getEntriesAdded()      public  int getEntriesRemoved()      public  int getEntriesUpdated()      public  int getFlushCount()      public  int getHitCount()      public  int getHitCountSum()      public  int getMissCount()      public  int getMissCountSum()      public  int getStaleHitCount()      public  int getStaleHitCountSum()      public  void scopeFlushed(ScopeEvent event)      Event fired when a specific or all scopes are flushed. public  String toString()      Return the counters in a string form.
