    • getCacheHits

      public long getCacheHits()
      Specified by:
      getCacheHits in interface javax.cache.management.CacheStatisticsMXBean
      Returns:
      the number of hits

    • getCacheHitPercentage

      public float getCacheHitPercentage()
      Returns cache hits as a percentage of total gets.
      Specified by:
      getCacheHitPercentage in interface javax.cache.management.CacheStatisticsMXBean
      Returns:
      the percentage of successful hits, as a decimal

    • getCacheMisses

      public long getCacheMisses()
      Specified by:
      getCacheMisses in interface javax.cache.management.CacheStatisticsMXBean
      Returns:
      the number of misses

    • getCacheMissPercentage

      public float getCacheMissPercentage()
      Returns cache misses as a percentage of total gets.
      Specified by:
      getCacheMissPercentage in interface javax.cache.management.CacheStatisticsMXBean
      Returns:
      the percentage of accesses that failed to find anything

    • getCacheGets

      public long getCacheGets()
      The total number of requests to the cache. This will be equal to the sum of the hits and misses.

      A "get" is an operation that returns the current or previous value.

      Specified by:
      getCacheGets in interface javax.cache.management.CacheStatisticsMXBean
      Returns:
      the number of hits

    • getCachePuts

      public long getCachePuts()
      The total number of puts to the cache.

      A put is counted even if it is immediately evicted. A replace includes a put and remove.

      Specified by:
      getCachePuts in interface javax.cache.management.CacheStatisticsMXBean
      Returns:
      the number of hits

    • getCacheRemovals

      public long getCacheRemovals()
      The total number of removals from the cache. This does not include evictions, where the cache itself initiates the removal to make space.

      Specified by:
      getCacheRemovals in interface javax.cache.management.CacheStatisticsMXBean
      Returns:
      the number of removals

    • getCacheEvictions

      public long getCacheEvictions()
      Specified by:
      getCacheEvictions in interface javax.cache.management.CacheStatisticsMXBean
      Returns:
      the number of evictions from the cache

    • getAverageGetTime

      public float getAverageGetTime()
      The mean time to execute gets.

      In a read-through cache the time taken to load an entry on miss is not included in get time.

      Specified by:
      getAverageGetTime in interface javax.cache.management.CacheStatisticsMXBean
      Returns:
      the time in µs

    • getAveragePutTime

      public float getAveragePutTime()
      The mean time to execute puts.
      Specified by:
      getAveragePutTime in interface javax.cache.management.CacheStatisticsMXBean
      Returns:
      the time in µs

    • getAverageRemoveTime

      public float getAverageRemoveTime()
      The mean time to execute removes.
      Specified by:
      getAverageRemoveTime in interface javax.cache.management.CacheStatisticsMXBean
      Returns:
      the time in µs

    • increaseCacheHits

      public void increaseCacheHits(long number)

    • addGetTimeNano

      public void addGetTimeNano(long duration)
