Cache for presentation by
 Cache.stats(). This is solely intended for consumption by Cache implementors.| Modifier and Type | Method and Description | 
|---|---|
| static StatsCounter | disabledStatsCounter()Returns an accumulator that does not record any cache events. | 
| static StatsCounter | guardedStatsCounter(StatsCounter statsCounter)Returns an accumulator that suppresses and logs any exception thrown by the delegate

 Use  recordEviction(int)instead. This method is scheduled for
     removal in version 3.0.0. | 
| default void | recordEviction(int weight)Records the eviction of an entry from the cache. | 
| void | recordHits(int count)Records cache hits. | 
| void | recordLoadFailure(long loadTime)Records the failed load of a new entry. | 
| void | recordLoadSuccess(long loadTime)Records the successful load of a new entry. | 
| void | recordMisses(int count)Records cache misses. | 
| CacheStats | snapshot()Returns a snapshot of this counter's values. | 
void recordHits(@Nonnegative int count)
count - the number of hits to recordvoid recordMisses(@Nonnegative int count)
Cache lookup methods with the same
 key on an absent value should result in a single call to either recordLoadSuccess or
 recordLoadFailure and multiple calls to this method, despite all being served by the
 results of a single load operation.count - the number of misses to recordvoid recordLoadSuccess(@Nonnegative long loadTime)
recordMisses(int), this method should only be called by the loading thread.loadTime - the number of nanoseconds the cache spent computing or retrieving the new valuevoid recordLoadFailure(@Nonnegative long loadTime)
