          long getReturnedCount()

    - #### getCreatedCount

          long getCreatedCount()

    - #### getReleasedCount

          long getReleasedCount()

    - #### purge

          void purge()

      Purges all connections in the pool. For connections currently in use, these connections will be purged when returned on the pool. This call also purges connections that are idle and in the pool To only purge used/active connections see `purgeOnReturn()`

    - #### purgeOnReturn

          void purgeOnReturn()

      Purges connections when they are returned from the pool. This call does not purge idle connections until they are used. To purge idle connections see `purge()`

    - #### resetStats

          void resetStats()

      reset the statistics of this pool.
