stop

@DontInline
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

stopInPartition

@DontInline
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

attachTo

protected void attachTo(BasePartitions partitions)

attachTo

protected void attachTo(BaseRows rows)

onClose

protected void onClose()

Description copied from class: Transformation

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

Overrides:

onClose in class Transformation<I extends BaseRowIterator<?>>

onPartitionClose

protected void onPartitionClose()

Description copied from class: Transformation

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

Overrides:

onPartitionClose in class Transformation<I extends BaseRowIterator<?>>
