      Modifier and Type Method Description
      protected void attachTo​(BasePartitions partitions)  
      protected void attachTo​(BaseRows rows)  
      protected void onClose()
      Run on the close of any (logical) partitions iterator this function was applied to We stipulate logical, because if applied to a transformed iterator the lifetime of the iterator object may be longer than the lifetime of the "logical" iterator it was applied to; if the iterator is refilled with MoreContents, for instance, the iterator may outlive this function
      protected void onPartitionClose()
      Run on the close of any (logical) rows iterator this function was applied to We stipulate logical, because if applied to a transformed iterator the lifetime of the iterator object may be longer than the lifetime of the "logical" iterator it was applied to; if the iterator is refilled with MoreContents, for instance, the iterator may outlive this function
      protected void stop()
      If invoked by a subclass, any partitions iterator this transformation has been applied to will terminate after any currently-processing item is returned, as will any row/unfiltered iterator
      protected void stopInPartition()
      If invoked by a subclass, any rows/unfiltered iterator this transformation has been applied to will terminate after any currently-processing item is returned
