List of hitRate() Examples

Examples of hitRate()

com.google.common.cache.CacheStats.hitRate()
Returns the ratio of cache requests which were hits. This is defined as {@code hitCount / requestCount}, or {@code 1.0} when {@code requestCount == 0}. Note that {@code hitRate + missRate =~ 1.0}.

Examples of com.google.common.cache.CacheStats.hitRate()

    subtree.addInt("missCount", stats.missCount());
    subtree.addInt("requestCount", stats.requestCount());
    subtree.addInt("totalLoadTime", stats.totalLoadTime());


    subtree.addFloat("averageLoadPenalty", stats.averageLoadPenalty());
    subtree.addFloat("hitRate", stats.hitRate());
    subtree.addFloat("loadExceptionRate", stats.loadExceptionRate());
    subtree.addFloat("missRate", stats.missRate());
  }
