Method Summary

Modifier and Type	Method and Description
RangeTombstoneMarker	applyToMarker(RangeTombstoneMarker marker) Applied to any RTM we encounter in a rows/unfiltered iterator

Row	applyToRow(Row row) Applied to any row we encounter in a rows iterator
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
