Class TemporalRow

java.lang.Object

org.apache.cassandra.db.view.TemporalRow

public class TemporalRow
extends java.lang.Object

Represents a single CQL Row in a base table, with both the currently persisted value and the update's value. The values are stored in timestamp order, but also indicate whether they are from the currently persisted, allowing a TemporalRow.Resolver to resolve if the value is an old value that has been updated; if it sorts after the update's value, then it does not qualify.
