long getPutCount()
```
    The number of cache puts into the region since the last Statistics clearing
  - getHitCount

  - getElementCountInMemory
```
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 ExtendedStatisticsSupport. If the provider does not support extended stats, NO_EXTENDED_STAT_SUPPORT_RETURN is returned instead.
  - getElementCountOnDisk
```
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 ExtendedStatisticsSupport. If the provider does not support extended stats, NO_EXTENDED_STAT_SUPPORT_RETURN is returned instead.
  - getSizeInMemory
```
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 ExtendedStatisticsSupport. If the provider does not support extended stats, NO_EXTENDED_STAT_SUPPORT_RETURN is returned instead.
