Package org.apache.druid.segment

Class RowPointer

java.lang.Object

org.apache.druid.segment.TimeAndDimsPointer

org.apache.druid.segment.RowPointer

All Implemented Interfaces:

Comparable<TimeAndDimsPointer>

public final class RowPointer
extends TimeAndDimsPointer

Extension of TimeAndDimsPointer, that keeps "row number" of the current data point in some collection of data points, that actually makes this data point to be called "row", and the collection, thus, "collection of rows". However, "row number" doesn't affect the TimeAndDimsPointer.compareTo(org.apache.druid.segment.TimeAndDimsPointer) contract. RowPointers could be compared to TimeAndDimsPointers interchangeably.
