Method Detail

applyToPartitionKey

public abstract DecoratedKey applyToPartitionKey(DecoratedKey key)

Description copied from class: Transformation

Applied to the partition key of any rows/unfiltered iterator we are applied to

Overrides:

applyToPartitionKey in class Transformation

applyToPartition

public abstract UnfilteredRowIterator applyToPartition(UnfilteredRowIterator partition)

applyToPartition

public abstract SearchIterator<Clustering<?>,Row> applyToPartition(SearchIterator<Clustering<?>,Row> partition)

applyToPartition

public abstract java.util.Iterator<Row> applyToPartition(java.util.Iterator<Row> partition)

applyToDeletionInfo

public abstract DeletionInfo applyToDeletionInfo(DeletionInfo deletionInfo)

applyToRow

public abstract Row applyToRow(Row row)

Description copied from class: Transformation

Applied to any row we encounter in a rows iterator

Overrides:

applyToRow in class Transformation

applyToStatic

public abstract Row applyToStatic(Row row)

Description copied from class: Transformation

Applied to the static row of any rows iterator. NOTE that this is only applied to the first iterator in any sequence of iterators filled by a MoreContents; the static data for such iterators is all expected to be equal

Overrides:

applyToStatic in class Transformation

applyToMarker

public abstract RangeTombstoneMarker applyToMarker(RangeTombstoneMarker marker)

Description copied from class: Transformation

Applied to any RTM we encounter in a rows/unfiltered iterator

Overrides:

applyToMarker in class Transformation
