Examples of CacheStats

com.google.common.cache.CacheStats
Statistics about the performance of a {@link Cache}. Instances of this class are immutable.
Cache statistics are incremented according to the following rules:
- When a cache lookup encounters an existing cache entry {@code hitCount} is incremented.
- When a cache lookup first encounters a missing cache entry, a new entry is created.
  - After successful creation {@code missCount} and {@code createSuccessCount} areincremented, and the total creation time, in nanoseconds, is added to {@code totalCreateTime}.
  - When an exception is thrown during creation {@code missCount} and {@code createExceptionCount} are incremented, and the total creation time, in nanoseconds, isadded to {@code totalCreateTime}.
  - Cache lookups that encounter a missing cache entry that is pending creation will await creation (whether successful or not) and then increment {@code missCount}.
- When an entry is evicted from the cache, {@code evictionCount} is incremented.
- No stats are modified when a cache entry is invalidated or manually removed.
- No stats are modified by operations invoked on the {@linkplain Cache#asMap asMap} view ofthe cache.
