NO_EXTENDED_STAT_SUPPORT_RETURN	back to summary
public static final long NO_EXTENDED_STAT_SUPPORT_RETURN The value returned from `getElementCountInMemory`, `getElementCountOnDisk()` and `getSizeInMemory()` for cache providers that do not support such "extended" statistics.

Method Detail

getElementCountInMemory	back to summary
public long getElementCountInMemory() The number of elements currently in memory within the cache provider. This is an optional value contingent upon the underlying cache provider providing extended stats support via `org.hibernate.cache.spi.ExtendedStatisticsSupport`. If the provider does not support extended stats, `NO_EXTENDED_STAT_SUPPORT_RETURN` is returned instead.

getElementCountOnDisk	back to summary
public long getElementCountOnDisk() The number of elements currently stored to disk within the cache provider. This is an optional value contingent upon the underlying cache provider providing extended stats support via `org.hibernate.cache.spi.ExtendedStatisticsSupport`. If the provider does not support extended stats, `NO_EXTENDED_STAT_SUPPORT_RETURN` is returned instead.

getHitCount	back to summary
public long getHitCount() The number of successful cache look-ups against the region since the last Statistics clearing

getMissCount	back to summary
public long getMissCount() The number of unsuccessful cache look-ups against the region since the last Statistics clearing

getPutCount	back to summary
public long getPutCount() The number of cache puts into the region since the last Statistics clearing

getRegionName	back to summary
public String getRegionName()

getSizeInMemory	back to summary
public long getSizeInMemory() The size that the in-memory elements take up within the cache provider. This is an optional value contingent upon the underlying cache provider providing extended stats support via `org.hibernate.cache.spi.ExtendedStatisticsSupport`. If the provider does not support extended stats, `NO_EXTENDED_STAT_SUPPORT_RETURN` is returned instead.
